Glaze frits


Untitled Document

Frits are a combination of materials melted together to render them insoluble and resistant to acid attack. They are a method of introducing certain materials into a glaze which would otherwise be toxic.

Frits can be used alone as low temperature glazes e.g. raku or majolica but generally form the basis of glaze recipes to:

  • Lower the melting point of a glaze as a flux
  • Render otherwise soluble materials insoluble in the glaze (ie prevent soaking and crystallizing on pot surface)
  • To give a more predictable and uniform rate of fusion (perhaps lower melting point)
  • By introducing materials free of volatiles (prevent pinholing etc)
  • To provide an even colouring effect from oxides and satins (avoid speckling)
  • To stabilize a glaze before firing (prevent shrinkage cracks, peeling and crawling)

A frit melts very rapidly at a specific temperature.
