These pieces after undergoing size and quality classification as defined in other pages are exported. Mica blocks are irregular in shape.
Mica Thins
Pieces of mica block having a thickness range between 2 mils to 7 mils are classified as mica thins. These are used to manufacture fabricated mica, description of which has been given elsewhere in this book.

Pieces of high quality mica having thickness generally less than 2 mils are classified as condensor films. These films are used in the manufacture of silver mica plates used in mica capacitors.
Mica Splitting
Pieces of medium quality mica having a thickness of less than 1 mil are classified as mica splitting. These splitting are supplied either “Bookform” type or “Loose” type. These splitting are used in the manufacture of Micanite related products .
