Make n Bake Polymer Clay Signature 400g

Mont Marte Make n Bake Polymer Clay 400g — the bulk size for serious sculpting, classroom projects, and anyone working at scale. Same workable, oven-bake clay as the 60g blocks, just six times more of it.

How it works: stays soft on the bench, bakes hard in a standard oven at 130°C for ~20 min per 6mm of thickness. No kiln needed.

6 colours available

Beige · Black · Scarlet · Sky Blue · Sunflower · Titanium White — the everyday workhorse colours in the larger format.

FAQ

What's the difference vs the 60g? Same clay, larger block. Better value per gram for bigger pieces or repeat use.

Does it dry out? Polymer clay doesn't air-dry — it only hardens with heat. Keep an open block wrapped in cling film between uses.

Is it safe for kids? Yes — non-toxic. Adult supervision needed for the oven step.

Can I mix colours? Absolutely — knead two colours together to make custom shades. Marbled effects work brilliantly.
