Plasticine clay is a boon for mold makers in more ways than one. It is easy to mold and will not dry in the presence of air. However, demolding calls for care and attention so that the details don’t get ruined.

There is clay and then there is plasticine clay. The best part about plasticine is that it is oil-based and non-drying. Therefore, it will not harden when exposed to air and can be used multiple times. This clay lends itself well not just for mold making, but is also commonly used for sculpting, mask making, special effects and clay animation. Moreover, top quality Plastilina clay is formulated in varying degrees of hardness to suit the requirements of the seasoned mold makers and sculptors.

The clay can be molded by hand by shaping and pinching it as desired or even by rolling it into coils and slabs. Alternatively, it can be shaped over a master model to capture the external shape and form down to the minutest undercuts and other details.

Demolding Clay

However, how will the mold maker get the clay off the master is another question altogether. The permanent pliability itselfcan become a drawback here as demolding the clay can distort the shape and details of the mold.

Here, the material and shape of the model will come into play. If it is made of porous materials and has a standard shape, the mold will be easy to demold. Peel it off with a slow and steady hand; do not pull unnecessarily as this will affect both the silhouette and the inner details.

However, when making a mold of non-porous materials like metal, plastic or glass, it is better to use a release agent before applying the clay. So is the case if the model has deep undercuts or indentations.

For simple molds, a dusting of talcum powder can do the trick. Or special release agents are available that make demolding an easy and safe process. Keep in mind that the mold should not be baked or frozen. This can work for regular clay but is not advisable when working with plasticine.

Similarly, harsh materials can cause the plasticine clay to distort and melt. So, never use solvents, rubbing alcohol and the like. On the contrary, soap or solvents can prove handy when the mold maker wants to clean leftover clay from the model. Soaking in hot water or washing with soap will clear the residues and return the model to its original condition.

In sum, clay modeling is easy and enjoyable; knowing some simple tips and tricks can make the results even better!
