Frits, glazes & engobes
Imerys talc – a key ingredient in frits, glazes and engobes
In
frit composition, talc with a very low iron content provides magnesium in the frit which:
- improves thermal expansion and fusion
- gives good melting behavior
In
fritless glazes such as
sanitaryware glazes, Imerys talcs enable manufacturers to lower barium carbonate and zinc oxide levels:
- enhancing whiteness
- improving acid resistance
- increasing glaze-body fit
- reinforcing crazing resistance
- reducing pinholes
- reducing formulation costs
Used as a matting agent in floor tiles, Imerys talcs improve whiteness without affecting expansion, abrasion and stain resistance. Used in combination with calcined alumina, they deliver excellent satin finish glazes with good fusibility and low thermal expansion, improving glaze body fit and reducing pinholes.
Talc reduces gloss gradually so it is a more effective matting agent and less harsh than alumina and wollastonite.
In wall tile engobes, talc with a very low iron content provides zirconium silicate savings.
Combined with magnesite and kaolin, talc improves the efficiency of refractory engobes used to protect ceramic kiln rollers.
