What is Mica Glass?

Mica is a transparent mineral used in older, antique wood and coal stoves. It has the appearance of clear plastic like plexi-glass or a heavy cellophane. Mica glass is also refired to as Isinglass.   It is Very thin yet durable.  It can withstand temperatures of about 1800 degrees F. Because it is a naturally occurring mineral, several smaller pieces are cheaper to produce and cost less than one larger piece. 

Woodstove-fireplaceglass.com now sells Isinglass – Mica in various sizes. 


What type of glass can I use for my Antique wood or coal stove?

Many of the older “pot belly” stoves have a small vision window for checking on the fire.  Mica or Isinglass was used in these openings.  Mica is so thin that it is flexible.  So, it is perfect to conform to the round body found in these older antique stoves. 

Mica can easily be cut with scissors, a razor blade or paper cutter.  We like to use an Exacto knife or razor blade.  We feel you get a cleaner cut using one of these. 

What is Mica Glass for Wood Stoves?

Mica stove glass is transparent, thin slices of mica stone, generally 0.003 to 0.005 inches thick, that can endure temperatures as high as 1800° F (982° C). Yet it can easily be cut to size with scissors, a paper cutter, or an Exacto knife.

Mica has excellent electrical, physical, mechanical properties and good thermal strength. It is transparent, has good optical properties, is flat, and virtually unbreakable. All these properties make mica is a material ideal for use as a window in wood and coal stoves.

Making its first appearance in wood stoves during the 1700s, mica glass panels were used in lanterns, stoves, furnaces, and boiler peepholes. With a clear to bronze tint, mica glass sheets look remarkably similar in appearance to translucid plastic. They are made by carefully stripping away paper-thin layers of mica away from the main, quartz-like stone.

How do you Clean Mica Glass?

Using a soapy non-abrasive cleaner, drip a couple drops on to a clean soft cloth.  Add a little bit of water and gently rub on the glass in a circular motion.  Rinse off with water. Dry the glass with a 3rd clean cloth so as to not leave any residue behind.

Is there anything else to keep in mind when ordering Mica glass?

Yes, Mica Glass expands slightly when heated. So please order or cut the mica glass to size so that it is a ⅛ inch smaller than the intended frame to allow for this thermal expansion.

Mounting hardware, such as brackets and metal screws, also expand under heat. Over-tightening hardware can cause the glass to break when the stove is in use.  We recommend installing the screws “finger tight”.
