Keep your polymer clay workspace cleaner and easier to use with this compact Cornstarch Powder Box.
Designed for polymer clay makers, this tool helps keep cornstarch, release powder, or similar powder more contained during the clay cutting process. The divided tray provides space for powder, while the removable grid insert helps shake off excess powder from cutters or small clay pieces before cutting or shaping.
It is especially useful when working with detailed cutters, textured clay pieces, small charms, earrings, and other handmade clay jewelry projects.

Recommended Use & Tips
• Recommended clay thickness:
1–4 mm for most earring designs.
For petal designs, try using clay under 1 mm for a more refined, lightweight finish.
Thicker clay creates softer details, while thinner clay may be more delicate after baking.
• For best cutting results:
Dip the cutter edge lightly in cornstarch or water if the clay feels sticky.
• Clean cuts tip:
Press the cutter straight down firmly and evenly. Avoid twisting, as this may distort the shape.
• Before baking:
Remove excess clay around the edges gently with a blade or needle tool for a cleaner finish.
• Baking tip:
- Follow the temperature and time recommended by your clay brand.
- For best results, use a separate oven thermometer, as oven dials can be inaccurate.
- Allow pieces to cool completely in the oven before handling to avoid cracking or breakage.
