Many people have said that cold porcelain clay melts in extreme heat and water. This is not entirely true. If you seal your finished pieces with a sealer your work will be well protected. Varnish sealers are inexpensive and easy to find at your local arts n crafts store or online. Once I left a charm I made with cold porcelain clay in my car on an extremely hot day. When I returned it was still as I left it. in perfect condition and not melted. I didn’t even seal it with a sealer that day. To go a bit further with my experiment, I dropped a bead I made in a tall glass of water and let it sit for half hr. Well the waterproof sealer held up to its name and my bead was still in tact. So if people make it seem that cold porcelain clay is extremely fragile that is untrue in my opinion. This is a great clay that I find is so much easier to work with than polymer clay. It’s so incredibly smooth, durable, pliable, holds fine detail extremely well and is very versatile. My mission is to try to do many techniques with cold porcelain clay that has also been achieved with polymer clay. For all you polymer clay lovers, Make way for the fast rising star, Cold porcelain clay! Happy crafting!!
