Mica, or fish class, forms in thin, transparent layers.
Better known as muscovite, isinglass is a form of mica often found in bed sheets. The leaves are often very thin, transparent, and somewhat elastic in nature. Russia and India have been sites of continuous mining for mica sheets. This mineral can be found in different natural formations, including granites and gneisses.

Muscovite’s designation for the fish class originates from the mineral’s common use in the country of Russia. Around the city of Moscow, the material is often used for window panes. The specific formula used to create these transparent and colorful panels is known as musky glass.
Isinglass is understood to be formed by a process that, over time, involves the natural alteration of various minerals into thin layers that can be extracted and used for a number of different products. Minerals such as kyanite, feldspar, and topaz are often cited as building blocks for creating classes of fish. Once the mineral is mined, it can be used for applications other than creating window glass. One of the properties that makes it so attractive is that the material lends itself well to colouring, which allows transparent or translucent color mixtures to be given to the finished product.
Isinglass is aptly known as Muscovite and is often used as window glass in Moscow.
Today, isinglass is sometimes used to protect a number of different products from fire, including durable fabrics and items used for camping and other sports. It can also be used for insulation, and the substance is often used as an additive to create roll insulation, as well as foam chips that can be blown into walls. The material can also be melted down and used in different types of machine lubricants, although it does not appear to work well in general-purpose lubricants. Glass products continue to be a popular choice for use, both as window glass and for a wide range of other items.
