This is the most commonly used firing. The way you paint the low fire glazes, they will always come out the same color with no to very little variation. This is glaze that can become unstable at higher temperatures. Some problems that occur with low fire are:
- the clay body may remain overly porous
- low-fire glaze colors can appear raw-looking
- many of the traditional glaze materials used in this range are quite toxic in their raw state.
- Low fire glazes mostly need a top clear coat in order for them to be food safe.
High fire:
A lot of high fires are porcelains and stonewares. Because of the varying effects of oxidation and reduction on glaze colorants, there are very limited glazes and effects that high fires can produce and you never know exactly how the product will turn out.
