Sema Coffee Cup Dual Battery Plaster Mold  (R21247)

Sema Coffee Cup Dual Battery Plaster Mold 

This professional 3-piece battery-style plaster mold is designed for the efficient production of "Sema" ceramic coffee cups. Specifically engineered for slip casting with ceramic or porcelain clay, this dual-cavity mold produces two units per casting, making it an essential tool for high-capacity ceramic studios and professional workshops looking to maximize productivity.

• Wipe the internal surfaces with a damp sponge before use to ensure they are free of dust and debris.
• Thoroughly mix the casting slip (using an electric mixer or wooden spoon).
• Prepare the slip 24 hours in advance and use sodium silicate (glass water) during the mixing stage for ideal fluidity.
• Pour the slip slowly, filling both cavities of the mold to the brim.
• Depending on weather conditions, 2–4 casts (4–8 units total) can be performed per day.

Minor exterior imperfections on the mold do not impact the quality of the final casts. The integrity of the internal cavities is the primary factor for achieving professional and smooth results.
