![]() It will break or cut cleanly, without a crumbly texture. It will be difficult to break, but if it is thin it might bend easily. When polyclay is cured correctly, your cooled piece can be marked when you press a fingernail into it, but your nail won't sink in. #3: How Do You Know When Polymer Is Done Baking? Start your stopwatch and then bake for the normal time. After the ten mins are up, set the dial to theĬorrect temp. Then preheat your oven to about 20 degrees below the Here's what to do. Place ceramic tiles into your oven to bake on. If you find that you are burning projects even if you're using a good thermometer, this might be the problem. Unfortunately this can scorch translucent or thin pieces when you're baking polymer clay. Your oven temperature 'spikes' Some ovens are manufactured with a built in quick heating cycle and use a higher temp than the dial setting in order to bring the average internal temperature up faster after the door is opened.More time, just as if you were baking a cake. High altitudes (above 3,500 feet) You’ll need higher temperatures and a bit High elevation baking If you are located at.Consider curing your pieces in your larger home oven inside an oven baking bag. Keep your pieces as far away from the heating elements as possible.Reduce the oven’s temperature by 10 degrees C (18 F degrees) and double the cooking time. Bake a testing sample and do a breakage test (see the Test Baking box below).This halts any additional curing from residual internal heat that may push the translucent over the edge from cured to yellowed. Do NOT do this if you have inclusions that may absorb water or if your piece is built upon a porous armature. Try dunking your piece into ice water immediately after taking it out of the oven.Your oven could also be 'spiking' (keep reading down this list for more info on this). At some point it is getting too high and slightly burning or browning the clay. Get a GOOD separate thermometer (or two) and watch that oven temperature like a hawk. ![]() They will hold heat and even out the oven's temperature after you open the door to put in your pieces. Place your pieces (and their holder like a cookie sheet) on top of the ceramic tiles when baking. Pre-heat for at least 15 minutes to get them hot. Are your translucent or light colored clays yellowing or scorching? Put some glazed ceramic tiles into your oven before baking.They will tell you the right temperature to use and how long to cook it. #2: How Do You Find the Correct Temperature?Īs Albert might say about baking polymer clay, ‘It ain’t rocket science kiddo!’ Read the directions on the package. With plenty of water and essentially boiled the water in the microwave.īaking polymer clay isn't the only way, but it is the easiest and gives you control over the most important variables. It in a microwave! What these crazy experimenters did was cover the polyclay DON’T try to cure your polymer piece by just sticking In electric roasters, tossed in fry pans on a bed of plaster of paris powder, boiled,įried, and even microwaved. It’s been hardened with heat guns, cooked Most polymer ‘oven clay’ hardens and cures with sufficient heat forĪ long enough time. And that makes certain techniques impossible, like creating canes that have spreadable slices. ![]() That dries at room temperature, but it has a limited working time.
