What is reactive glaze?

Reactive glaze is a type of ceramic glaze that creates unique and varied patterns or colors when fired in a kiln. The term "reactive" refers to the way the different chemicals in the glaze interact with each other during the firing process, resulting in unexpected and often beautiful effects.

These glazes are typically made with a combination of metallic oxides, such as copper, cobalt, or iron, which react with the other elements in the glaze to create colors that shift and blend during firing. The final appearance of a reactive glaze can be difficult to predict, making each piece of pottery or ceramic ware truly one-of-a-kind.

Reactive glazes are popular for their organic, natural-looking finishes that can resemble natural stone, watercolor paintings, or even wood grain. They are often used in artisanal pottery and tableware to add depth and character to the finished piece.

It is important to note that reactive glazes can be more difficult to work with than standard glazes, as their unpredictable nature can sometimes result in undesirable outcomes. However, many ceramic artists and potters embrace the variability of reactive glazes as part of their creative process.
