glazury
Glazury are vitreous coatings fused to ceramic bodies during firing, forming a glassy surface that is normally smooth, impermeable, and decorative. They serve functional purposes such as water resistance and chemical durability, and also provide color, texture, and gloss. Glazes are applied as suspensions or slips before firing and melt to form a durable ceramic glaze layer.
Glazes are composed mainly of silica as a glass former, with fluxes that reduce the melting temperature,
Application and firing: Glazes are applied to bisque-fired forms by dipping, pouring, brushing, or spraying. After
Types and characteristics: Historically important glazes include lead glazes and tin glazes; contemporary ceramics often use
Defects and safety: Common glaze problems include crazing, pinholing, crawling, and blistering, usually caused by mismatches
