20g

A 20g (0.7 oz) block of polymer clay is a pocket-sized, oven-bakeable crafting material. It is roughly the size of a matchbox (4.5 cm x 3.5 cm x 1 cm) and is usually sold in multi-color starter packs.

Quick Facts

• What it can make: 1–2 pairs of small earrings, tiny dollhouse miniatures, or fine detail accents for larger sculptures.

• Key feature: It is PVC-based, meaning it never air-dries and stays soft until you bake it.

• How to harden: Bake it in a standard home oven at 130°C (275°F) for about 15–30 minutes.
