Mont Marte Air Hardening Modelling Clay

Mont Marte Air Hardening Clay is the perfect choice for professional modellers, artists and students alike. This heavy-bodied clay is pliable after kneading, and because it is slow drying you can take your time forming it into your desired design.

The clay is suited to free form sculpting and can be sanded, drilled, painted or vanished once dry. Almost any decorative object can be created with imagination. Dries in around 24hrs to earthenware hardness (depending on thickness). Traditional pottery techniques can be used together with non-traditional methods such as stamping or adding objects to your work.


Available in White & Terracotta, 500g & 2kg.


  • Fine Even Texture
  • Easy to smooth
  • Make highly detailed pieces
  • Standard pottery tools can be used with Mont Marte Air Hardening Modelling Clay
