Not rated to be used on any cooking surfaces.

Mica Glass Sheet 4 by 6 Inch | Isinglass Window


Also known as isinglass, mica glass is used on antique wood, European, and coal stoves. It has even been uses on certain furnace windows. This transparent mineral has the appearance of clear plastic and a thickness of .003 to .005 inch. However, mica can withstand temperatures of 1800° F. Need to clip a corner or cut it to a slightly smaller size than this 4 by 6 inch sheet? This is easily accomplished using a pair of scissors.

Please Note: This is the only size available; if you need to cover a larger area, you will need to piece multiple mica glass panels together.

What is isinglass?

Isinglass is a thin, transparent sheet of mica which is a silicate mineral. Because this material is highly resistant to extreme temperatures and less likely to shatter under these conditions, it is perfect for use in small windows on furnaces, heating stoves, and peepholes in boilers. Care and maintenance is easy:

  • Gently rinse off the isinglass window with clean water. 
  • Dilute approximately 1 pint of water with 3 drops of mild non detergent soap.
  • Wash the isinglass with a soft cloth and soapy water solution.
  • Rinse thoroughly with fresh, clean water and another clean soft cloth.
  • Dry the window with a third clean absorbent cloth or towel.
