== Frit ==

Frit is glass that is in a crushed form. Frit varies in size from quite chunky pea sized pieces to sandlike consistancy.

Frit is larger than [[powder]] but smaller than [[cullet]] glass. Available in all commonly used artistic glasses, frit comes in most colors, as well as clear. Most of the major suppliers of [[soft glass]] and [[borosilicate]] glass sell frit grade glass in a variety of grades.

Application of frit can be done on the surface of a piece or on the inside of a tube if a hollow vessel is being formed. Care should be taken to fully fuse the frit if applied to the inside of a tube. Many frits are made with highly reactive colors, and will want to reduce upon application, working in the back of a good oxygen rich flame helps keep these colors stable untill they're fully fused into the surface of the glass.

Frit is usually made through a mechanical crushing operation, but can also be made by rapidly cooling hot glass in water. For small quantities a cheap thrift-store variety electric coffee grinder makes frit out of any color or combination of colors the artist needs. Commercially the frit is graded by size through a stack of sorting screens. In the studio you can sort the larger frit from powder with a kitchen strainer.

Frit should be kept away from children and never inhaled.
