Frequently Asked Questions

What are these rubber straps used for?

These straps are used to hold plaster mold sections firmly together during slip casting and clay press molding. They prevent the mold halves from separating under the pressure of liquid slip or clay, ensuring clean seams and leak-free pours.

What sizes are included in the set?

The set includes 11cm, 16cm, 19.5cm, 24cm, and 28cm straps — one of each. The smaller sizes suit cups, bowls, and small figurine molds; the larger sizes are ideal for plates, vases, and larger vessel molds.

How do I choose the right strap size for my mold?

Select a strap that fits snugly around the widest circumference of your mold with moderate stretch. The strap should hold the mold halves firmly without being so tight that it distorts the mold or so loose that it slips during use.

Are these straps reusable?

Yes. The heavy-duty rubber construction is designed for repeated use. Rinse with water after each session to remove slip residue and allow to dry before storing. Avoid prolonged exposure to direct sunlight, which can degrade rubber over time.

Will these straps work on non-round molds?

Yes. The elastic rubber stretches to conform to round, oval, and irregular mold shapes, making them versatile across a wide range of mold types used in ceramic production.

Can beginners use these straps?

Absolutely. These straps require no tools or special technique — simply stretch over the mold and position as needed. They are a standard tool in both beginner pottery classes and professional ceramic production studios.
