Polymer clay can be stored at room temperature for extended periods of time, but it will last even longer if kept in a cooler place, such as in your refrigerator. Some people even freeze their clay. (Just be sure, if you put it in either place, that the clay doesn’t come into contact with food!)
How long can you keep polymer clay?

Can you store polymer clay in Ziploc bags?

What happens if you bake polymer clay too long?
Longer baking will also lead to stronger clay projects. If your clay is burning, the temperature of your oven is too high. Address your temperature, not your bake times! That being said, longer bake times can cause some colors of polymer clay to darken.
What can I do with unused clay?
You can recycle clay, or reclaim clay, so it can be used again. Many potters keep their non contaminated (21) clay scraps from trimming, broken greenware, or old throwing slurry (3) to recycle and reuse. As long as clay has not been fired it can be recycled (10, 21).
Can you leave polymer clay out overnight?
No, you cannot air-dry polymer clay. Polymer clay has to be baked at the correct temperature for it to harden. If you leave it out in room temperature, you do not have to worry about it hardening before you’re ready to bake. If you need to step away from your project for a few hours, no problem.
Does polymer clay harden after baking?
Most polymer ‘oven clay’ hardens and cures with sufficient heat for a long enough time.
Does Sculpey shrink when baked?

Does Sculpey go bad?
If it is stored correctly, polymer clay lasts indefinitely (a decade or longer). However, it can dry out and it’s possible to ruin it under certain conditions.
Can you bake polymer clay with wire in it?
You can use a wire armature to stiffen the extended parts of a Sculpy (polymer clay) figure, and bake it without the piece cracking, unlike the way ceramic clay behaves.
How long can I leave polymer clay before baking?
It is suggested that thicker pieces be initially baked for 15 minutes, then another 5 minutes, another 5 minutes, etc. The clay needs at least 15 minutes to cure properly. Strength increases as the baking time increases.
How do you store unused modeling clay?

How do you know when polymer clay is done baking?
Bake for 15 minutes per quarter inch of thickness. For example, a piece of 1/2″ thickness should be cured for 30 minutes. To test the curing, try pressing the tip of your fingernail into the bottom of your piece after it has cooled; it will leave a mark but will not actually enter the clay.
How do you smooth polymer clay after baking?
Sanding Clay Sandpaper is used to sand your clay after it has been baked, however you must make sure that you are using Wet/Dry Sandpaper so that you can keep the polymer dust out of the air and use it with water. Wet/Dry Sandpaper is Black in colour as opposed to orange or brown.
How do you harden polymer clay without an oven?
When you don’t want to cure clays that harden at a specific temperature in the oven, you can use a heat gun, hair dryer or heat-embossing tool set to the desired temperature. Place the polymer clay creation on a nonstick surface, such as a piece of ceramic tile or block of wood.
Can you use old polymer clay?
Unless clay is already cured, it can be brought back to life with enough work. The way you soften hard polymer clay is a combination of working (conditioning) it and adding new materials to make it more supple and workable.
Why does my polymer clay crack after baking?
When the clay cracks after baking, it means you’re baking at too low of a temp, and for too short of a time. I recommend using a convection oven, for one, if you can. But you also need an oven thermometer.
