FAQ
Is Jesmonite safe to use?
Yes! Jesmonite is water-based, non-toxic, and solvent-free. We do recommend gloves to avoid skin contact and a mask during powder mixing.
How long does it take to cure?
About 30–45 minutes under pressure, depending on the temperature.
Can I mix colors?
Absolutely! You can create marbled, layered, or solid color effects.
How should I take care of my die?
Avoid rolling it on hard surfaces to prevent damage. Use a dice tray or soft mat. Re-apply beeswax every 6 months to keep it protected.
Can I ink the numbers?
Yes! We’ll show you how to ink the numbers with acrylic paint. It’s optional, but really makes the details pop.
Can I make more than one die?
One chunky D20 is included in the workshop price. Depending on time and availability, you might be able to make extras for a small fee.
