Do or did ceramic or porcelain wall or floor tiles contain asbestos or lead?

Do or did tile grout, tile bedding compounds, thin-set mortars, or tile mastic used with ceramic tiles contain asbestos or lead?

We explain the ingredients in ceramic floor tiles, cite authoritative research on the presence or absence of asbestos in these ceramic tile, or its absence, and we point to sources of confusion about the question of which ceramic products (tiles, pottery, filters) contain or ever contained asbestos as a filler or as a fiber strengthener.

We include research citations indicating various hazards in the production of some tile products.

We report on an international survey of certified asbestos testing laboratories who were asked for their experience in receiving ceramic tile samples or mortar/grout samples and testing them for asbestos content.

Does Ceramic Floor Tile or Ceramic Wall Tile Contain Asbestos?

Is asbestos found non-resilient flooring such as ceramic floor tiles?

Our page top photo illustrates a fragment-section of old ceramic floor tile. At left we show a side-view or cross-section of how this old ceramic floor tile was installed by bedding it directly into concrete. We would not expect to find evidence of asbestos in this tile installation.

[Click to enlarge any image]

This example was found in a pile of demolition debris left at a building renovation site. The tile was set into and well bonded to concrete, and was removed under wet conditions.

The short answer for now appears to be "yes and no" depending on the tile and tile grout age and source, as follows:

• Artists materials including ceramics, clays, glazes often contain a variety of hazardous materials including arsenic, asbestos, lead, silica.
  
  See ASBESTOS in CERAMIC MATERIALS
• Ceramic floor and wall tile produced in North America would not be expected to contain asbestos.
  
  However you may find asbestos in some tile grouts and thinset tile mastics and possibly in hand-made tiles made as part of an art project using art clay.
• Ceramic floor and wall tile produced outside of North America may contain asbestos depending on where it was produced and what additives were intentionally or accidentally included by the manufacturer.
  
  This may be true particularly for files produced in the Mediterranean area [44] and for some ceramic tiles made in China, as we discuss in more detail
  
  at CHINESE CERAMIC TILE ASBESTOS

• Ceramic tile grout may contain asbestos as we discuss
  
  at CERAMIC TILE GROUT ASBESTOS
• Non-ceramic floor tiles such as terrazzo floor tiles (and possibly some unglazed ceramic quarry tiles), produced both in the U.S. and from other countries may contain asbestos depending on its formula.
  
  Some "manmade" "terrazzo" consisting of concrete, marble, and/or epoxy alone won't contain asbestos.

Details, including authoritative citations and an ongoing survey of the results of tile testing at asbestos testing labs in the U.S., Canada, Japan, Korea, the U. K. and other locales are provided below.

OPINION: researching this question we find that the dominant opinion among experts and amateurs is that ceramic tiles are made of clay subjected to high temperatures and finished with a hard glazed surface. Not asbestos.

If there are some ceramic tiles whose clay source included asbestos or to which asbestos was added [a topic of ongoing research that we report and update below] the tiles are nevertheless a non-friable material that would not normally be a hazardous source of asbestos in buildings.

Non-friable materials are hard and do not easily release particles into the indoor environment.

Watch out: grinding, tile-saw cutting, sanding or similar activities performed on ceramic tiles of any composition could produce fine dust and debris that should be controlled and treated as a respiratory hazard, asbestos-containing or not.

Do Ceramic Floor or Wall Tiles Contain Dangerous Levels of Asbestos or Not ? - research question status

Deliberate Inclusion of Asbestos as an Add-in to Ceramic Tiles?

Asbestos could have been included in some ceramic floor tile formulas into the 1970's as a filler or in fiber form as a strengthener.

At least one asbestos testing lab director reports that asbestos is found in ceramic tiles made in some parts of the world such as the Mediterranean area and in unglazed terrazzo (non-ceramic) tiles.[44]

Below at CHINESE CERAMIC TILE ASBESTOS we discuss reports of asbestos in some recent Chinese ceramic tile and flooring products.

Don't Confuse Asphalt-based or Vinyl-based Asbestos-containing Floor Tiles with Ceramic Tile Products

In our flooring photograph at left, the floor and stair tiles may be vinyl-asphalt or vinyl-asbestos floor tiles but they are not a ceramic product. For information about asbestos-containing vinyl or asphalt-based floor tiles,

see ASBESTOS FLOORING IDENTIFICATION.

Certainly as we see in Rosato [23], the asbestos industry was constantly looking for uses of asbestos mining waste products that included granular asbestos dust and short asbestos fibers.

Although we cite field and lab reports and research in this article, we have not yet located an authoritative reference source (text, journal article, government document) that documents the deliberate or accidental inclusion of asbestos material added to modern (20th century and later) ceramic floor or wall tiles made in North America. Please contact us if you have such information.

In contrast, it is certain asbestos was used in those forms in vinyl-asbestos flooring (a different material from ceramic tiles). And as we document below, asbestos was used in mixture with ceramic fibers (for certain products such as filters) and in ancient pottery applications.

Our photo above illustrates a floor tile installation in Barcelona, Spain. These floor tiles are estimated at more than 50 years old.

Do new ceramic tiles from China contain asbestos?

The ceramic tile that we purchased for our bathroom wall was made in China. What are the chances that it would contain asbestos? - question from Anon by private email 2017/03/24

A quick search for "Asbestos in Tile from China" intended to collect results on asbestos in ceramic tile made in China found these interesting and suggestive results, giving a definite possibility that your Chinese-made ceramic tiles could contain asbestos.

The most strongly-worded material comes from news reports, after which I cite some more-scholarly research on asbestos in Chinese ceramic tiles used on walls and floors.

• "Asbestos warning on tiles from China", ABC News Australia, 14 Feb 2010, retrieved 2017/03/24, original source: http://www.abc.net.au/news/2010-02-15/asbestos-warning-on-tiles-from-china/331176, Quoting:
  
  A safety alert has been issued about wall tiles imported from China which may contain a deadly form of asbestos. WorkCover New South Wales says the decorative white natural stone tiles may contain tremolite - a form of asbestos.
  
  WorkCover says importers should contact their suppliers to check that the tiles do not contain the substance. If the tiles do contain tremolite, they should be disposed of at an approved asbestos waste facility.
  
  WorkCover says importers and retailers who suspect they may have tiles containing tremolite should contact WorkCover immediately. - This is a news report not a scholarly-research article - Ed.

What is the Composition of Ceramic Tiles?

Is there Accidental Inclusion of Asbestos in Clays Mined for Use in Producing Traditional Ceramic Tiles?

The term "clay" refers to both a particle size (smaller than 2-4mm) and a type of rock or mineral comprised of fine-grained sheet silicates.[48] The fine-grained clays used to manufacture ceramic tiles include basically compounds of silica, alumina, and varying amounts of metallic oxides and other impurities. [32]

Ceramic tiles are made from natural clay [such as Cretaceous clays [30] (not asbestos)] or porcelain, and are glazed or un-glazed.

Typical ceramic tile composition (in more detail) includes 33% refractory clay, 20% quartz, 45% sodium feldspar. Other sources list common tile ingredients including aluminum oxide, zirconium oxide, and quartz (silicon dioxide). Other ceramics have more complex formulas.

Ceramic tiles

are made of clay (predominantly feldspar), water, and some mineral additives, processed with high heat to solidify the product and whose top or exposed surface is sealed with a glaze.

Porcelain tiles

are a harder ceramic tile made of kaolin mixed with china stone, or in other sources, by using ground sand. Porcelain is heated to a higher temperature than other ceramics (more than 2000 degF) and is more dense than ceramic materials made of clay.

Many other materials have been included in clays used in making various ceramic products since the Stone Age (pottery) and continue to be added to give special properties or colors to modern ceramic tiles, including perlite, fly ash, granite stone grinding and cutting waste, etc. Indeed expert sources date the oldest known ceramics date to 27,000 BCE.

The oldest known ceramics made by humans are figurines found in the former Czechoslovakia that are thought to date from around 27,000 B.C.E.

It was determined that the figurines were made by mixing clay with bone, animal fat, earth, and bone ash (the ash that results when animal bones are heated to a high temperature), molding the mixture into a desired shape, and heating it in a domed pit.

The manufacture of functional objects such as pots, dishes, and storage vessels, was developed in ancient Greece and Egypt during the period 9000 to 6000 B.C.E. [33]

  • Asbestos in clay products:
    
    Asbestos has been reported in art clay (such as Fibro-Clay)[37] used in schools and in pottery clay where it occurred in the form of talc added as a flux to lower the firing temperature.
    
    Talc and clay from at least one U.S. mine contained anthophyllite asbestos. It was unclear whether or not this material fell under the aegis of asbestos regulation.[36] The asbestos content of talc depended on where it was mined, and some talcs were asbestos-free[40].
    
    Depending on the quarry source there may be deliberate or accidental inclusion of asbestos in terra cotta tiles such as roofing tiles.
    
    Other clay products that may have had asbestos added in the form of talc or vermiculite (some vermiculite contains asbestos) in addition to art clays, may include clays used as pipe joint seals or insulation, and in the production of firebricks used to line the combustion chambers of heating equipment such as boilers or furnaces, and other school art projects such as paper maches.[38][39]
  • Pre-historic origins of use of asbestos in clay pottery:
    
    The use asbestos-strengthened ceramic wares (pottery) dates from the Stone Age and continued throughout the Bronze Age and into the Iron Age.
    
    Specifically, asbestos fibers were used to strengthen earthenware pots and cooking utensils as long s 4,500 years ago, an application documented by various sources.[26] Also, a Wikipedia entry on Asbestos-ceramic describes pottery made with asbestos and clay [25].
  • Asbestos textiles: 
    
    Were used as safety protective clothing & gear for workers in the ceramics industries - a possible source of confusion associating the terms "ceramic tile" and "asbestos" in some search engine results.

Do ceramic tiles risk releasing harmful particles into indoor air?

Ceramic floor or wall tiles of any formula, if in good condition have a low, most likely negligible risk of releasing harmful particles or fibers into indoor air. And a ceramic tile that comes loose intact or with a single break is also unlikely to release a measurable amount of dust or particulates into the building.

Watch out: Phillip A. Peterson Vice President Fibertec Industrial Hygiene Services, Inc.[49] advises that Although the tile themselves are unlikely to contain asbestos, the grout and bedding may well contain asbestos and the demolition of the tile will likely create an exposure hazard when the grout and/or bedding are disturbed.

Ceramic floor tiles that are being demolished, ground, sanded, or cut with a tile saw, if they are old enough to have been installed when asbestos was in common use in grout, tile bedding, or (in newer homes) thin set or tile mastic, could be hazardous and should be handled appropriately.

If you are considering demolition of old ceramic floor tiles or similar materials, or are using a sander, grinder or tile saw on such materials, there could indeed be an asbestos hazard and you should follow appropriate handling, dust control, personal protection, and cleanup procedures.

If you have a segment of floor tile (or any material) tested for asbestos the test should be performed by a certified asbestos testing laboratory.

In Any Case, Better to Leave Asbestos-Containing Floor Tiles In Place

As with known or suspected asbestos-containing floor tiles (such as asphalt or vinyl-asphalt asbestos floor tiles), when it's feasible expert sources recommend leaving the original floor tile material in place and covering it over with new flooring.

Leaving asbestos-suspect flooring in place, even if you need to level the floor before it is covered with new material, is not only less costly than a professional asbestos abatement project, it also is likely to be the course with the lowest risk of asbestos dust or fiber release and contamination in the building. According to the US EPA {discussing asbestos abatement in schools] :

... In addition, abatement activities may create more of a hazard than would normally exist if the ACM were simply protected and maintained in good condition as is the case for ceramic floor tiles. ...[3]

Similar sources indicate that simple deconstruction of a building with appropriately careful disassembly of its parts may not require asbestos abatement. [4]

Survey Results: Accredited Laboratories Asbestos Fiber Analysis in Ceramic Tiles

Beginning in March 2012, and using the U.S. NIST directory of accredited laboratories certified for asbestos fiber analysis, [42] we polled at least one laboratory in each U.S. state, Puerto Rico, two Canadian Provinces, and laboratories in Japan and Korea, asking each if their laboratory had ever received ceramic tiles for asbestos testing and whether or not their lab had ever detected asbestos in ceramic tiles used on walls, floors, or other building services. Results are included below.

We asked:

"Can you tell us if your laboratory has ever received samples of ceramic wall or floor tile to test for asbestos, tell us if you have encountered asbestos in ceramic tiles used on walls or floors, and/or can you provide a reference to a paper, study, book, or expert who can tell us whether or not asbestos in any form was used in the production of ceramic wall tile or floor tile, or in terra-cotta or similar tile products."

and we invited technical review of the article found on this web page.

Notes to the table above:

(1) Survey initiated 3/8/2012

(2) Asbestos reported as extensive in ceramic tiles made out of North America, particularly in the Mediterranean area[44]

(3) Our calculated estimate of total number of actual lab samples processed by laboratories responding to the survey. Based on correspondence, e.g. P. P. to D.F. 3/14/12[49] estimated less than 150" tile samples over 20 years of ceramic tile, & 200 grout & bedding samples over 8 years of testing.

We estimated 6 tile samples per year or 25 grout samples per year per responding lab, and and multiplied that by known or estimated number of years of lab testing of tiles or grout. [E.g. 200 samples/8 yrs = 25 grout samples/year. 25 x 6(labs) x 10 yrs) =1500]

(4) In every case the asbestos mineral has been chrysotile asbestos and the concentration of asbestos has exceeded 2 percent (making them asbestos containing materials by definition). [49]

Watch out: while asbestos may be absent from your ceramic tile found on walls or floors, it may be present in joint compound used on drywall behind the tile or in some tile adhesive mastics. Also some ceramic tiles may contain lead.

Will I release dangerous asbestos if I clean these black and white ceramic floor tiles from a 1948 home in Georgia?

2018/05/06 Brittney said:

I’m wondering if you are able tell/may know if these floors contain asbestos just by looking at them?

My husband and I just purchased this house built in 1948 in Georgia. And I hadn’t thought much about asbestos in floors until finding this website and now I’m concerned. (See attached pic).

Do you think scrubbing the floors/grout should be safe ?

This question and reply were posted originally

at ASBESTOS FLOORING IDENTIFICATION

Reply:

It appears to me you're asking about a ceramic tile floor.

If That's the case, even if the style contained asbestos, which would be quite uncommon, the asbestos risk is beneath the limits of detection unless you're grinding chopping or sawing the material.

Cleaning the floor in your photos is not going to produce a measurable hazard even if there was asbestos in the tile or its grout - a situation that would be quite uncommon - as the materials are very hard and not at all friable.

Typically we need to use a liquid cleaner that includes mild bleaching agent to whiten the floor tile grout.

Reader follow-up: I don't want the Chinese ceramic tile in my home: plans to remove Chinese Ceramic Tile

Well the flooring says made in PRC.....that means People's Republic of China.

Ii realize where the "measurable risk" comes from but since my now deceased husband died of mesothelioma, from supposed MINIMAL exposure to asbestos I don't want ANYTHING containing asbestos in my home.

Unfortunately the ceramic tile has already been installed and that involved lots of cutting. The flooring has not so I will be returning it. I have contacted the company from which I purchased the material but have not yet heard back from them.

Reply: minimize the risk of installed Chinese asbestos-suspect ceramic tile

I don't blame you for taking these things seriously, and I'm cautious too about products from China - there have been enough disasters already.

What I meant by measurable risk is that installed ceramic tile is not going to release asbestos at detectable levels in a building unless it's disturbed.

While it's a different product (flooring) the US EPA advice on minimizing asbestos hazards in the home emphasizes that unless the asbestos-containing but non-friable material is damaged or being disturbed, the lowest risk to occupants is to leave it alone, or perhaps cover it over.

Removing it will expose you and the building and its occupants to a much greater risk, even if you hired a professional remediator who used negative air, containment, etc. (you're looking also at a very big cost).

OPINION: My advice is to leave the tile in place, or if it's going to make you worry - which is itself bad for us - you could consider laminating over the existing tile with a second layer of new material in which you have confidence.

That may at most require some adjustments at the tub/shower controls to bring them forward.

Question: does this [ceramic] floor tile contain asbestos?

My husband & I are planning on replacing the floor tile in our entryway. I'm trying to research to see if it could contain asbestos as we have two young children. Our home was built in 1965 in a Pittsburgh suburb.

Could you take a look at this picture and let me know what you think? Thank you! - anonymous by private email, 2016/07/15

Reply:

From your photo this looks like ceramic floor tile. If it is a modern, U.S.-made product it probably does not contain asbestos. However some mastic adhesives did contain asbestos so care in removing that material would be appropriate.

See ASBESTOS-CONTAINING ADHESIVES

If you cannot remove the flooring without making a dusty mess, it may be worth having a sample of tile and more-likely the adhesive mastic tested.

See ASBESTOS TESTING LAB LIST

If you do decide to have the materials tested let us know the result as that may help other readers.

On 2023-08-29 by Brian - Asbestos likely in 1960's ceramic tile in a Florida home?

My house was built in 1964 in Florida. I have 6x6 tiles that I believe are ceramic. What are the chances they contain asbestos? (I know I have asbestos in the popcorn ceiling already).

On 2023-08-29 by InspectApedia DF (mod)

@Brian,

It is unlikely if the tile was produced in the US. Although you may find asbestos in some tile grouts and thinset tile mastics.

Also keep in mind that even if the tiles did contain asbestos, if in good condition, they are nevertheless a non-friable material that would not normally be a hazardous source of asbestos in buildings

Please read more above on this page.

On 2023-09-01 by Brian

@InspectApedia DF, so it should be safe to remove the tile, grout and thin set so long as we are careful not to damage it too much?

Thank you.

On 2023-09-01 by InspectApedia Publisher

@Brian,

We don't know if your ceramic tile, grout, and adhesive mastic contain asbestos or not. Even if not, silica dust is hazardous, so if you're chopping grinding sawing the hazard is increased.

Beyond that, as I can't see the job and have no specifics, any answer is - sorry - just too speculative to be accurate.

 

On 2022-01-19 by Ryan - Boss didn't check ceramic tiles or mastic fdor asbestos

Just having to reno a bathroom. Boss didn't check tiles and mastic for asbestos. Nor did he check the multiple layers of vinyl tilea/sheet vinyl.

These tiles look old enough to be a concern for at least grout/mastic exposure.

They have been painted white.. which also makes me wonder if someone else knew they contain asbestos. Thoughts?

 

On 2021-11-16 by Asbestos grout in kitchen...?, is it safe to live-in or even visit these apartments or condos?

Whats the percentage/chance that the grout would contain asbestos in kitchen counter and bahtroom please in California? High chance?

Now I feel worried to use the counter as mugs and pots are coming with contact with the kitchen tiles/grout every day.

Is it even safe to live in these possible asbestos houses? And is the garage and window safe in your opinion?

And when they cutting walls on that neighbours house without protections and just throwing in a truck without putting in bags, is that something to worry about, or is that normal procedure and the possible asbestos would not really affect house next to it or air while walking around the house.

Wondering also how safe it is to visit them. Thank you! - Ryan
