Dipping & Stuccoing

• The shell building technique involves dipping and stuccoing the assembly into a ceramic slurry and then into a bed of extremely fine sand. After drying, the process is repeated. Up to 7 layers may be applied in this manner. Successive coats of ceramic slurry and refractory sand, fused silica are applied on assembled cluster/tree with intermediate drying time to form a self-supporting ‘Shell’ or called ‘Mold’.
