Glaze

A glaze is simply a layer of glass that is fused to a clay body during firing. It provides a decorative surface and increases the strength of the ware. A glaze allows for a nonporous surface that provides a hygienic covering as well as contributing its beauty by adding color, texture, and shine. Glazes can be sprayed, brushed, or dipped. Once the glaze is applied to the ware and the water evaporated, it actually becomes a layer of powder. During firing the fluxes and stabilizers cause the glaze to turn molten and fuse to the clay body.

Commercially prepared glazes have many advantages, especially for the beginning ceramist. Commercial glazes are prepared under strict conditions and are guaranteed for consistency. There is a huge variety of colors and effects available to the ceramist. Glazes can be purchased in ready-to-use jars or you can purchase glaze in powder form, which has a longer shelf life and takes out the extra water weight, reducing shipping costs. To mix your own glazes from scratch, you would need special equipment and the facility to store the glaze components. If you do want to mix your own glazes, try a simple formula with only a few ingredients to start. (See simple base glaze with added commercial stains to develop a color palette.) There are more complicated recipes available that yield unique results but require toxic additives. Taking a professional course on handling glaze ingredients will save you time and money in the long run. Please follow the material warnings and handling instructions to the letter and wear protective equipment. Nothing is as important as your health and well being.
