A glaze is a smooth, shiny coating applied to pottery or ceramics to enhance their appearance and protect them. It is made from a mixture of minerals and water, which is then fired in a kiln. This process creates a glass-like surface that can be colorful and decorative, making the pottery more appealing and durable. In addition to pottery, glazes are also used in baking, particularly on pastries and desserts. A sweet glaze, often made from sugar and water, adds flavor and a glossy finish to items like donuts or cakes. This technique not only improves the look but also enhances the taste of the food.
