Crushed glass coasters & trivets made in the USA from recycled bottles. We make these in squares, circles and hearts! The semi-porous surface is perfect for serving your favorite cup of coffee, fancy mixed cocktail or that fantastic glass of wine. While the heat resistant nature of glass and pottery allows them to double as hot plates or candle holders. Choose the glaze to complement your home and decor, all while extending the life of your tables and countertops.
