Temperatures feature a lot when working with polymer clay.
First, there’s the room your clay is stored. If it’s cold, your clay will be cold and therefore take longer to condition. This can be frustrating if you want to start your project right away. So check the temperature of the room and warm it up a bit.
Similarly, if the room is too hot, your clay will be too soft to handle. It's great for conditioning but as you start to work with to create your design, you will find it's difficult to slice and to mold into the shapes you want.
Second, as you work with the clay, you’ll find it softens and warms up. This is why it’s always a good idea to leave a cane for about 10 to 15 minutes to rest before slicing. The clay is basically cooling down. Your slices will likely be crisper and show the pattern better if you do this.
Finally, your oven temperature is crucial. All polymer clay manufacturers have written guidance on the packages detailing oven temperatures. I highly recommend using an oven thermometer to confirm the temperature as oven heat does fluctuate.
If you have any experiences where temperatures affected your clay, share them.
