Ceramics Glazes

Choose a glaze based on the type of clay (earthenware, stoneware, porcelain), firing temperature of your kiln (low-fire, mid-fire, high-fire), desired surface (matte, satin, gloss), and function (food-safe, decorative). Check manufacturer labels for cone range and compatibility with your clay body

Common finishes are matte (soft, low-sheen), satin (subtle sheen), gloss (high shine), and specialty effects like crystalline, ash, or metallic lusters; each alters color depth and light reflection and may change slightly after firing depending on temperature and application thickness

Some glazes are formulated and tested as food-safe; confirm by looking for manufacturer statements about food safety and lead/cadmium testing, and ensure proper firing schedule—unglazed or improperly fired surfaces can leach contaminants

Coverage depends on application method and piece size, but small bottles (4–8 oz) are common for test work and touch-ups while larger pints or quarts suit production; ceramic glazes in home decor categories typically range from budget options under $20 up to specialty or larger-volume jars over $100, with many products averaging in the mid-range

Apply evenly—brush, dip, or spray with consistent thickness, clean bisqueware of dust and oils, allow adequate drying before firing, follow the manufacturer's cone and firing schedule, and avoid over-thick application to reduce crawling, pinholing, and running

Store glazes in airtight, labeled containers at stable room temperature, stir or shake before use to remix settled solids, and add a small amount of water if slightly thickened—discard if moldy or if separation cannot be remixed uniformly

Useful items include brushes of different sizes, dipping tongs, spray guns or airbrushes for even coats, glazing buckets, sieves for straining, pH and lead test kits for safety checks, and kiln wash or stilts to prevent pieces from sticking
