Frits are parts of a glaze recipe that have been melted and ground to be added into a new glaze recipe. Frit 3124 is one of the most popular and useful frits due to its almost glaze-like chemical balance. The material is a source of calcium boron in glazes and can be used to make wall tile and pottery glazes. This frit melts at a low temperature and has medium thermal expansion, making it fit most clay bodies.
