Asbestos Used in Organs, Pianos & Piano Parts
When and in what forms was asbestos used in pianos, organs, and similar instruments?

Asbestos found in some piano and organ components:

This article describes the common forms in which asbestos was used in pianos, player pianos, and organs. The article lists common uses of asbestos in these musical instruments and gives the brands and dates of manufacture of asbestos-containing pianos using Starr pianos as a key example.

Asbestos was used in some piano padding and may have appeared in several other forms such as fiber cement asbestos millboard in instruments built for use in humid climates.

Asbestos Used In Pianos & Piano Parts & in Organs

Reader Question: Did the Starr Piano company use any asbestos in any part / parts in there Star Remington Model?

Reply: Here are some example photos of standard, non-asbestos piano materials found in Starr pianos as well as advice on where to look for asbestos products

Thank you for the interesting Asbestos question about pianos. Certainly where asbestos is a general concern, an inspection onsite by an expert will provide far more assurance about asbestos risks than we can provide by web discussion.

[Click to enlarge any image] That said:

Asbestos was used in some piano padding. I have not found a referral to asbestos specifically used within pianos themselves. However it wouldn't surprise me if pianos made for humid climates didn't use asbestos millboard for some component parts.

According to our research, The Starr Piano Company was established in Richmond, Indiana in 1872. The pianos were manufactured and distributed under the labels of Cumberland, Duchess, Gennett, Krell, Minum, Tayser, Royal, Pullman, Remington, Richmond, Coronado, Schmoller & Mueller and Starr Pianos.

Some Starr piano owners and references refer to these labels as "models" of the Star piano line.

While asbestos was widely used in many products at that time, the Cumberland photos we've seen, at least of piano exterior, use the expected wood case and hard white and black keys that may be ivory and ebony or celluloid, typically glued over wood.

Some Places to Look for Asbestos Material in a Piano

Piano key hammer felt: The white piano key hammers (photo at left of a Starr piano interior) could have been made of asbestos as that product was listed by Rosato.

Key hammer felt in most pianos is more typically organic fibers. See Rosato's reference atReferences or Citations . Note that most piano key felts are and were fabricated from wool.

Piano key hammer damper felt or cloth: the damper felt used under or behind piano keys may have contained asbestos, as cited above.

Cement asbestos millboard: Does your Starr Remington model piano include the lighted music well unique to the Starr piano line? Without having found details about the construction of the light well, I pose that a manufacturer might have used cement asbestos millboard as a light well liner for fire safety.

Dampness controls in pianos: including cement asbestos millboard components used for the construction of pianos intended to survive in damp envronments and dampness removing systems in pianos such as "Hydroceel" tubes. (Den Boer 1973 cited below).
Also see CEMENT ASBESTOS SHEET PRODUCTS

Insulation used in some pianos included vermiculite. Depending on where the vermiculite was mined it may contain asbestos. See VERMICULITE INSULATION

Light wells & light wiring: You'd want to look inside an antique piano for any questionable material such as asbestos millboard such as hidden structural components in a piano made for humid climates or around electrical components - look at the surrounding material used in the luminous music well if your Starr piano has that feature.

Because theatre wiring often used asbestos insulating jackets and because the light wiring on a piano light well might be subject to high temperature, that's another place to look.

Music racks on pianos: some piano music racks included asbestos in the 1940's, and other music racks that included lighting may include asbestos in electrical wiring insulation or heat shields. (McKenzie 1911 & Janssen 1942)

Player piano parts, incuding the piano suction turbine, discs, and other parts (Cushing 1964). Asbestos is cited as a component in the suction pump assembly of [presumably] some player piano brands and models. (Kinsler 2002)

If you have specific materials in mind from your piano then, can you send me [CONTACT] some sharp photos of the whole piano, its identifying marks/labels including inside the unit, photos of the parts in question. I can thus advise you about further sampling and testing as well as considering the question about whether or not testing is warranted.

Do not disturb asbestos unnecessarily:

Finally, as with many asbestos-containing materials, especially non-friable materials like asbestos cement millboard, the more significant asbestos hazard would arise if you were demolishing or grinding or cutting the material. Leaving it alone or coating it in place are usually advised.

Reader Question: asbestos in 1920's Janssen Piano?

I am restoring an old Janssen piano circa 1920. I was reading your article on Asbestos in Pianos and wondering if you would please tell me if my piano may have asbestos? - Anonymous, by private email 2016/05/21

Reply:

I can't know just from your e-text. The article above lists some of the ways asbestos may have been used in pianos.

Asbestos was widely used in many brands of Pianos and may not have stopped in most countries until the late 1970's in North America or as late as the 1990's in the U.K. and some other countries.

However some piano manufacturers indicate that their pianos never contained asbestos.

If you can, send me some sharp photos of the piano and of asbestos suspect parts, I can comment further, and course know for sure you have to obtain a lab test. [Done, above].

Piano Manufacturers Who Did Not Use Asbestos

• Yamaha Pianos [citation needed]

Piano Manufacturers Known to Have Used Asbestos in Piano Parts

• Baldwin Pianos may have contained asbestos, as the Baldwin Piano factory in Cincinnati Ohio is listed among workplaces posing a hazard of jobsite asbestos exposure.
• Bentley [citation needed]
• Emmery [Uncertain, citation needed]
• Kemble [citation needed] upright pianos

Piano Manufacturers who May have Used Asbestos in Piano Parts

• [citation needed]

Piano Parts Accessories that Used or May Have Used Asbestos

• Piano Felt components such key hammers or strikers may have used asbestos (Zumbro 1932)
• Padding used in pianos: felt strips may contain asbestos
• Panels comprising pianos made to withstand damp or humid conditions were sometimes made using asbestos-cement board.
• Piano Dehumidifiers: installed in pianos located in very humid locations where humidity might damage piano components or cause mold growth, some dehumidifiers use asbestos-contaminated vermiculite.
  
  See details at VERMICULITE HISTORY & PROPERTIES
• Piano Humidifiers: Hydroceels, often manufactured using semi-solid asbestos bars; a "hydroceel" is a moisture-generating bar installed in pianos and kept damp in order to avoid piano damage should the internal relative humidity level fall too low. In short a hydroceel is a piano humidifier.
  
  The Hydroceel is often placed just inside the piano behind a front panel and running at right angles to the piano strings. In that location the device is humidifying piano strikers as well as wood components.

Question: does our Metzler baby grand piano contain dangerous asbestos?

My sons’ piano teacher in the UK has a baby grand Metzler, it’s very old. I’m afraid it might contain asbestos but I’ve no way of finding out. Is it a reasonable worry please or is it unlikely? - Anonymous by private email 2020-01/28

Photos above and below: these are NOT the reader's Metzler baby grand but they do illustrate a Metzler baby grand piano for sale (the detailed view) or recently sold (full view of a Metzler baby grand piano) at auction by worthpoint.com/, retrieved 2020/01/28 original source https://www.worthpoint.com/worthopedia/metzler-baby-grand-piano-514505995 (piano for sale)

Reply:

I did some research looking for any documents describing the construction of Metzler pianos without useful result. Metzler, a UK firm based in London, produced a wide range of upright and baby-grand pianos between the company's founding in 1788 and (we think) the 1930s.

Metzler was also a UK music publisher for more than 100 years, between 1820 and the 1920s.

My best advice on the question of whether or not your Metzler piano contains asbestos is organized on this page., where we describe what sorts of piano parts (using asbestos cement board panels and on occasion asbestos-containing key hammers) might contain asbestos.

Unless parts on your Metzler are damaged, friable (soft crumbly), or thus shedding dust, even if asbestos was used, its' not likely that it's producing a significant level of airborne asbestos.

If it were my piano and I had your concern I'd inspect it carefully for damaged soft components and I might take a sample of any candidates, such as of one of the piano felt key hammers, to have tested by an asbestos test lab - the cost of that test is around $100. U.S. or perhaps less.

I'd like to see a photo of the piano, of its nameplate, and of its interior and key striking mechanisms.

Metzler also made upright pianos as illustrated just above, op. cit. We have no information confirming (nor denying) the use of asbestos in these pianos.

A nice nano-history of Metzler & Co. is given by Horniman Museum and Gardens who describe the company as "(active 1833 - 1931).

• The Horniman Public Museum And Public Park Trust 100 London Road Forest Hill London SE23 3PQ 020 8699 1872 - Website excerpt:
  
  Metzler & Co. was a firm of London-based piano makers. The company was founded in 1788 by Valentin Metzler, and became known as Metzler & Son in 1816 when his son George Richard joined the firm. In 1833 the company name changed to Metzler & Co., presumably on Valentin's death.
  
  The company was taken over on George Richard's death in 1867 by his son George Thomas. Metzler & Co. exhibited a piano at the Great Exhibition in 1851. The firm became a limited company in 1893, and was taken over by J. B.

I have a Grinnell Bros. Console Piano. The Serial No. is 4-3066. The Antique Piano Shop advised the piano was built in 1947. 1. Do you know if this is correct? 2. Did this company put asbestos in their pianos?
3. If the manufacturer used asbestos and stopped the practice, please let me know the years their pianos were asbestos-free. Thank you very much!

Hi

I was given a Broadwood upright steel framed Grand Piano [rosewood] manufactured approximately 1945. It was refelted around 20 years ago.The piano was apparently shipped from the UK to Australia after WW2. I was wondering if the piano is likely to contain asbestos.
Thanks so much for your help,

Ted,

The Fender Rhodes electric piano is documented in patents dating from at lest 1965 - an era when asbestos was in common use and continuing into the 1980's. I searched the patents for the word "asbestos" as often the patent disclosure would document that situation. Asbestos doen't appear in the patents - not a conclusive result but a suggestive one.

United States Patent 0 Des. 200,439 Ce Patented Feb. 23, 1965 ELECTRIC PIANO Harold B. Rhodes, 2443 Greenbriar Sh, Anaheim, Calif., assignments, of one-half to Fender- Rhodes, Inc., Fullerton, Califl, a corporation of California Filed June 18, 1964, Ser. No. 80,469

Rhodes, Harold B. "Piano action." U.S. Patent 4,338,848, issued July 13, 1982.

Barona, Maria Elisa Ayerbe. "The fender rhodes." (2014). an article about this instrument that appears in various locales including one I cite below

Excerpt:
The Fender Rhodes electric piano is one of the most important musical inventions of the twentieth century. Harold Rhodes, a musician who worked as a flying instructor stationed in Greensboro, NC during the WWII, was asked to develop a musical therapy for wounded soldiers at the hospital. Rhodes designed a small piano that could be played in bed by the recovering patients. (Adlers)

The instrument was built with parts of aluminum tubes from a dismantled B-17 bomber plane which produced a special resonance. Rhodes used these as tuning forks for a 2½ octave (29 keys) acoustic piano instrument that resembled a xylophone. When the war ended, Rhodes manufactured an amplified 38-key electric version of his original instrument called the ‘Pre-Piano,’ with pickups for every tone bar, built-in tube amplifier and speakers. This instrument was presented at the NAMM convention in 1946. (Rhodes Music Corporation)
