The Peggy Karr 10-inch Glass Tray in Spice It Up design is both beautiful and practical, perfect for dining and serving, or as a stand-alone art piece. The red, green, and yellow chilipepper design is part of the piece - not painted on or applied with adhesives. Powdered pigments are used to create a design sandwiched between two pieces of glass. The piece is then fired at over 1500 degrees Fahrenheit, fusing the glass and permanently sealing in the design. The result is a durable, fade-proof dish that is microwave- and dishwasher-safe, and can be used every day. Please note that harsh detergents and hard water may cause clouding. Like all untempered glass, this dish is not oven-safe. Avoid contact with extremely hot food. Peggy Karr – functional art at its finest. Handmade in the USA.
