Ceramic Glaze Chemistry Flux
Stabilizer
Glass Former
Opacifier
Colorant Basic Components of Ceramic Glazes Barim Oxide
Calcium Oxide
Potassium Oxide
Sodium Oxide
Lithium Oxide
Magnesium Oxide
Lead Oxide
Strontium Oxide
Zinc Oxide Compounds Used as Stabilizers Is any ingredient that is
used to help melt the glaze or to lower the temperature that the glaze will melt at. Is any ingredient that
is used to extend the
melting range of a glaze and to stiffen the glaze. The main ingredient of a
glaze and the one that needs additional melting from the fluxes and stiffening from the stabilisers. Silica is the main glass former. Makes the glaze more opaque by obstructing the light as it passes through, often used to make a white glaze. These ingredients add
color to the base glaze
and are used in small
amounts, they are usually
metals in some form
like copper. Compounds Used as Flux Aluminum Oxide
Boric Oxide
Kaolin Compounds Used as Glass Formers Silicon Dioxide
