Will polymer clay air dry? Have you ever asked that question? I know that this is something being asked so I’ll give you my take on it and then some additional thought s of my own. The short version is no, you cannot air dry polymer clay as it was not designed to do so. There are other scenarios that may come into play, so I will go over them here in this post.
If exposed too long to air, this kind of clay can become dry, so it’s important to keep it stored in a cool, dry location. But that’s different from it actually becoming “cured”. Polymer cay can only be cured for certain in a home oven under the correct temperature and length of time.
So, nothing short of that will cure it fully, like using a blow dryer or anything. One small exception may be using a heat gun, and that may be limited to spot curing, as well as parts that involve the use of liquid clay.
Polymer clay CAN become dry if exposed to air – of course, it depends on how long. When I want to take a break from something I’m working on, I will usually cover my work-in-progress with some wax paper before calling it a day, or night., to keep it in optimum condition.
I don’t think anything can go wrong in as little as time as a day, but I DO want to keep my unfinished work free of floating dust particles and the possibility of stray cat hairs as my furkids are always nosing around – Please tell me I’m not the only one who’s fussy about icky stuff landing on her clay inadvertently😁 .
If exposed to prolonged heat or sunlight, there could be set in motion the possibility of the clay being partially cured– So definitely make sure if you’re working with it, keep it away from sun and UV light.
Also, keep in mind there’s a difference in it being in a “stiff” condition” and that of becoming unusable. If it does become stiff, the application of an oil-based product will be all you need to bring it back to life.

Now, if it crumbles, that could be a red flag – it’s not going to “come back to life” unfortunately. I’ve had this experience, and it was pretty vexing. I tried whatever I could to make it usable and still, no solution. When you get your hands on a block of clay, you will know right away, if it is just a little tough to work with, because – it may take a few minutes, but between the warmth of your hands and whatever substance you use it will start to cooperate.

There’s one thing to point out – and that Sculpey and Fimo have come out with an air dry clay. The Fimo Air also has a variation that can do a little time in the microwave! Pretty awesome right? However that’s the only exception. I have not tried it for myself and I’ve only found scant reviews so I can’t tell you how well it works.
I did however find an article detailing how to use it correctly. You’ll need to have a bowl with water in it and time it accurately for best results. But if you’re looking for a kind of polymer clay that can dry a different way, it may be worth looking into.
Well, that’s my take – the long and the short version of whether or not polymer clay will air dry….I hope it clarifies things for you going forward, and good luck to you.
