Little Square Condiment Dish - Fusible Glass Slumping Mold Mold measures approx. 3" L x 3" W x 1" H. To use, simply pretreat the mold with kiln wash or nitride spray, and slump your prefused or sheet glass (cut to size) using a slumping kiln schedule. For best results, always elevate this mold off the kiln shelf by at least 1" before firing to help prevent mold breakage. Comes with a complete New Hampshire Craftworks Mold Care and Firing Schedule included.
