Abstract
The present invention relates to a method of producing a ceramic material comprising the steps of: a) mixing a first clay composition comprising silica and a silicate mineral with a second clay composition; and b) firing the mixed clay composition from step a) to form a ceramic product. The present invention also relates to an engobe clay composition, sanitary ware and methods of productions thereof.
Claims29
A method of producing a ceramic material comprising the steps of:
- a) mixing silica and a silicate mineral and at least one first clay with a second clay which is different to the at least one first clay to form a silica/silicate clay mixture;
- and
- b) firing the silica/silicate clay mixture clay to form a ceramic material.
A ceramic material comprising:
- a) at least one first clay;
- b) a second clay comprising a fire clay;
- c) silica;
- and
- d) wollastonite.
An engobe clay composition comprising:
- a) one or more clays;
- b) a silicate mineral;
- c) optionally, an opacifier;
- d) silica;
- and
- e) one or more fluxes.
A method for producing an engobe composition comprising:
- a) adding water and silica to a mill;
- b) adding optionally an opacifier, one or more fluxes and a silicate mineral to at least one clay;
- and
- c) grinding the components in a) and b) to a suitable median particle size.
A method of manufacturing sanitary ware comprising
- a) mixing a first composition comprising:
- i) a silica/wollastonite slurry mixture having a median particle size of from 0.5 to about 10 microns;
- with
- ii) a first clay and a second clay;
- b) mixing the first clay in step a) with a fire clay;
- c) shaping the resulting composition;
- drying and firing the composition.
