- Engobe compound
- Base Glaze Compound
- Top glaze compound
A glaze is thin vitreous layer formed on the ceramic tile body. First engobe is applied which is the primary coating on the surface of the ceramic body and then base glaze which is called base glaze which is opaque in nature digital print is done and to protect the graphic or marble design top transparent coating is done which help to develop at desired darkness This glaze surface is having almost nil porosity after firing, resistant to acids house old chemicals and scratch resistant. Aesthetically after firing the surface of the glaze gives good appearance satin mat surface and with desired surface curvature and planarity passing through the polishing process glassy surface is obtained. Glaze is chemically alkaline in nature.
Glazes are classified as per the firing temperature
DFF (Double fast Firing) -1050 to 1080
Glaze vitrified -1180-200
Depending upon the temperatures composition is made suitable to the respective technology matching the thermal expansion of the glaze with respect to body
Glazes are consisting of the clays minerals and 30-40% of frit and some extent of of fluxes help the glaze to fuse at respective firing temperature Clays help for the suspension and help rheological properties.
ENDURA Glaze compounds are commercial and technically customised to provide the best aesthetic, technical & commercial value. Compounds are designed for desired thermal expansions, brightness and better colour development, resulting in less colour/ink consumption thus saving huge raw material & process cost.
ENDURA Glaze compounds are ready to use with addition of 30-35% of water in the ball mills after proper grinding and maintaining desired parameters of the glaze like residue and viscosity.
