Ceramic making is a delicate process, and creating plaster molds for ceramic is even more complicated. Ceramics are fragile, so much that we need to know how to take care of them so that they can last for a long time.
Plaster molds for clay or ceramics are easy to handle, which makes them a useful tool in the arts. They allow you to repeat an intricate pattern, so you don’t have to do the process over again. That is why it’s essential that we know how to take care of plaster molds for ceramics. Below are some useful tips.
Make sure that you have a smooth mixture to ensure that there won’t be lumps when the mixture is poured to set. You want a smooth ceramic once it has hardened. Mix only the exact amount that you need for your design. Once the mixture dries up, it will no longer go back to its fluid form. You only have one shot at getting the mixture right.
It is important that you use a mold release. Most artists use petroleum jelly as a mold release. Without a mold release, you might end up breaking the plaster mold you’ve just made and would have to make it over again.
As the mold dries up, secure it with a strap to prevent it from warping. You wouldn’t want your design to look twisted or bent. If you try to pull apart the plaster mold from the ceramic and it still sticks, do not jiggle it. Let it dry a little bit longer. If you force the mold open, then it might end up broken or the ceramic might not come out the way you want it to be. Give it ample time to completely dry up. Drying time varies depending on the surrounding temperature.
Don’t just be focused on your mold. See to it that your workplace is clean. Wash any metal object that you have used because plaster tends to make metal rust faster. If you leave metal tools unwashed, they might go to waste since you could still use them the next time you create pottery.
Since you’ll be using your plaster mold again the next time you create ceramics, clean the mold before keeping it. Molds should be kept in room temperature and the storage area should not be damp.
Talent and a passion for art is essential when creating attractive ceramics, but you should also know how to take care of your plaster molds for ceramics so that you’ll be able to use them for a long time. You might want to turn your pottery hobby into a business one day if you haven’t already.
