Casting Tips

  1. Mix the slip well with a mechanical mixer taking care not to introduce air which may appear later as pinholes in the fired object.
  2. Time how long you leave the slip to cast for consistent results.
  3. Trim the spare 10 minutes after draining the slip from the mold or as soon as the slip looses its gloss to stop the rim tearing. Use a thin cutting tool.
  4. Cast evenly, dribbles of slip or uneven wall thickness will cause distortion in the firing.
  5. J Cast is porcelaneous, translucent and hence slightly pyroplastic at cone 10. To avoid warpage make sure your casts are even and your setters and shelves are flat.
