high-fire glaze

High-fire glaze refers to a type of ceramic coating developed and fired at high temperatures, typically between 2,300 to 2,500 degrees Fahrenheit (around 1,260 to 1,370°C). This firing process causes the glaze to melt and chemically bond with the clay body, resulting in a durable, vitrified surface that is often glossy or smooth. High-fire glazes are valued for their strength, resistance to chipping, and rich, complex colors that develop during firing. They are commonly used in stoneware and porcelain ceramics for functional ware and artistic pieces, providing a high-quality, long-lasting finish.
