What are the different types of glaze in ceramics?
Basically, there are four principal kinds of glazes: feldspathic, lead, tin, and salt. (Modern technology has produced new glazes that fall into none of these categories while remaining a type of glass.) Feldspathic, lead, and salt glazes are transparent; tin glaze is an opaque white.
What makes ceramic glaze blue?
Cobalt is an extremely powerful colorant that almost always produces an intense blue. Cobalt carbonate tends to be used more by potters because it has a finer particle size and is less intense. In glazes with a high magnesia content, very small amounts of cobalt can give a range from pink through blue violet.
What are ceramic pigments?
A ceramic pigment is usually a metal transition complex oxide obtained by a calcination process which shows three main characteristics: (a) thermal stability, maintaining its identity when temper- ature increases; (b) chemical stability, maintaining its identity when fired with glazes or ceramic matrices; and (c) high …
What are the 4 main glaze types?
Typically glazes come in gloss, matte, semi-gloss and semi-matte, and satin matte. However, there are certain glazes that are specifically manufactured to have a unique textured finish.

What makes a glaze pink?
In the presence of tin oxide in calcium glazes, chromium turns pink. Only a very small amount of chromium is needed for this (0.1–0.5% with 5% tin). In glazes containing zinc, chromium forms brown zinc chromate. Chromium oxide is refractory and toxic.
How do you paint ceramic glaze?
