What the AI looks for in Clays & Doughs
- Curing method
- Choose kiln-fire clay only if you have kiln access; otherwise choose air-dry or oven-bake (polymer) clay. Kiln clays stay fragile and dissolve in water unless fired, which is the most common mistake in this category.
- Water and food use
- Only kiln-fired clay with a food-safe glaze is suitable for drinking or eating vessels. Air-dry clay softens when wet and polymer clay is not intended for food contact.
- Shrinkage and cracking
- Expect some shrinkage as clay dries; keep wall thickness even and dry slowly. Uneven thickness and fast drying cause cracks in every clay type.
- Finishing
- Air-dry clay needs a sealant or varnish after painting. Unsealed air-dry pieces absorb moisture and chip.
Brands that matter
- DAS: Widely used air-dry clay in white and terracotta.
- AMACO: Long-running maker of moist kiln-fire clays, self-hardening clay and glazes for schools and studios.
- Sculpey: Major polymer clay brand, from soft beginner clay to firmer Premo.
- Staedtler FIMO: Firm European polymer clay known for detail and strength.
- Crayola: Kid-focused air-dry clay and Model Magic.
- Creative Paperclay: Lightweight paper-based air-dry clay favored by doll makers.
What to avoid
- Using air-dry or polymer clay for cups, plates or vases that hold water.
- Putting air-dry clay in a kiln: it is not formulated for firing.
- Painting air-dry pieces and skipping the sealant.
Questions
Can I bake air-dry clay to speed it up?
Air-dry clay is meant to dry at room temperature; forcing it with heat tends to cause cracking. Only polymer clay is designed for oven curing.
What is the difference between polymer clay and real clay?
Polymer clay is a PVC-based material cured in a home oven. Real ceramic clay is earth-based and becomes durable and water-resistant only after kiln firing.
