Cleaning Molds for Making Ceramics
Clean molds allow individuals to make ceramic pieces that have no imperfections or embedded materials and debris in the slip. Extreme care should be used in the maintenance of molds. Any damage to a mold will show in the final ceramic piece. Molds need to be thoroughly cleaned following each use. Clean molds need to be stored banded in an upside down position. This will keep them free of dust and insect collection.

Some tips and suggestions for cleaning molds for making ceramics are in the following.

  • Design crevices often collect excess slip. Remove this by blowing hard into any section that is dirty. Never use canned air or forced air to remove debris or dirt. Never scrape away dirt or debris. This will scratch molds causing definite imperfections in pieces.
  • Wet slip should be allowed to dry for easier removal. Slip will shrink as it dries and be easier removed.
  • Use a soft brush to rid dust and debris. Large cosmetic brushes work adequately for this task.
  • Dampen a soft sponge with clean water to remove stubborn debris and dirt. Small sponge pieces can be used to keep amount of moisture to a minimum.
  • Allow molds to completely dry before using.
