These clays such as pottery clay, are very low cost clays, model well with normal pottery tools but have the disadvantage of drying out quite quickly and are very brittle and easily damaged. All work must be covered by a plastic sheet overnight to retain moisture.
Air hardening clays
Air hardening clays such as Das clay which is non-toxic has an even, fine, texture and are easy to smooth. They can be used on various supports such as wood or cardboard and are highly plastic and suitable for most modelling techniques.
Oven Hardening Clays.
These polymer clays, such as Sculpey Premo, have the advantage of being able to be carved or modelled by hand and subsequently hardened by heating in a household oven. This can have advantages when wishing to transport the finished model undamaged to another location or when using the model as the finished article.
Non- hardening clays.
These are probably the most popular of the clays for modelling and include Plastelina and Klean Klay. One of the advantages of non-hardening clay is that they do not dry out and become brittle while modelling. A disadvantage is that extra care must be taken not to damage the finished model while mouldmaking.
Klean Klay contains no sulphur and therefore can be used with all platinum based silicones while mould making.
