Today I’m stating baking temperature and also why it’s so crucial for getting good results through your polymer clay projects. When baking polymer clay, temperature is everything! This article is 2nd in a series on Baking Polymer Clay. Part 1 of this collection discussed choosing the best oven for baking or curing her polymer clay projects. Part 3 will be give details tips and tricks around baking polymer clay.

What temperature need to you roasted polymer clay?

All ovens lie, so acquire a thermometer to verify what the yes, really temperature is. Adjust the dial to obtain the correct temperature.For a an excellent cure through polymer clay, temperature is important!If your clay is burning, your cooktop is also hot. Period.Most polymer clay is far much more heat tolerant than you’d expect. It will not instantly burn at 1° above the encourage setting.Polymer clay does not burn and also turn black unless the stove is near 350°F (190°C).If you minimize the temperature out of fear of burning, you will underbake your project, which reasons your project to break.Different clay brands have different recommended temperatures. In most cases, aim because that the temperature ~ above the label.Most ovens have terrible temperature control, so baking is her most most likely culprit if you have breakage or browning.


not correct is nearly always resulted in by undebaking. One of the most crucial things you deserve to do to ensure good results is come invest in an oven thermometer. They’re not expensive and can typically be uncovered at many discount or kitchen stores for less than $10. Every range is different and many will run at a temperature much different than girlfriend set. Some ovens room too hot and others are too cool. Even an ext take a long time to acquire up come the correct baking temperature, also once the oven’s “preheated” light has actually come on. It’s always best to check. Get to understand your oven, watch what its sample is. Does it get to the correct temperature quickly? go it host the temperature or does that cycle wildly? This is such an essential factor that part professionals also recommend getting two thermometers simply in instance one of castle is wrong!

Underbaking Polymer Clay

Underbaked polymer clay will break easily. Underbaked translucent polymer clay isn’t together clear or translucent together it should be. That is extremely necessary to bake her polymer clay tasks no reduced than the encourage temperature because that at least the correct length of time.

Sometimes human being underbake your polymer clay due to the fact that they are afraid burning or scorching your clay. Placed your mind in ~ ease. As stated on the Polyform website, both Sculpey and Premo execute not failure and burn until the temperature will 350°F (177°C). The exact same is true for Kato Polyclay (as per personal communication v Connor Bizon, a chemist v Van Aken International.) Assuming your oven features properly and you set the correct temperature, you space far an ext likely to underbake than burn her clay.

Overbaking Polymer Clay

Scorching and also burning polymer clay is pretty nasty. Simply think that what any kind of burned plastic smells like! melted polymer clay does release small amounts the irritating and also caustic hydrogen chloride gas. If girlfriend burn her clay, rotate off the oven, open up the windows, and leave the area till it removes out. Just like when friend burn your pork roast. Yet aside indigenous airing the end the area and also throwing far the burned mess, girlfriend won’t have to undertake any “toxic waste cleanup” or decontamination of the area. Though the room and your oven might smell bad for a while (no various from when you burn popcorn in the microwave…yuck!)

But you’re not going come burn your polymer clay uneven you set the not correct temperature on her oven, your stove malfunctions, or your item is also close come the element. It’s straightforward to accidentally collection the not correct temperature, though. I’ve recorded myself law it number of times for the basic reason the Premo bakes at 275°F yet most of united state bake a casserole in ~ 375°F. So double-check and also don’t let your “autopilot” take it over! another thing that happens is there will certainly be clay cooling in the cooktop when one more person come along and turns the stove on come preheat for making food. Following thing friend know, your inventions are up in smoke!

Browning or Darkening of Polymer Clay

Even if your range doesn’t burn clay, it can still cause discoloration lot in the same means that bread transforms brown when placed next to the heating aspect (toast!). Translucent and lighter colored clays are really susceptible come this. I’ll talk about some means to avoid this and also protect your artwork in part three of this series. Yet remember the reducing your oven’s temperature (as verified by a separate oven thermometer) is not the solution. You will certainly just end up through underbaked, weak projects.

I to be so upset when these gorgeous translucent mokume gane beads came out of the oven yellowed and darkened. This experience made me look because that why this happened and find out exactly how to protect against it in the future.

Times and also Temperatures because that the best Results

Polymer clay manufacturers clearly state the encourage temperatures at which their products should be baked. Some brands warning you no to exceed details temperature ranges. This is rather understandable since manufacturers have to write instructions for ALL varieties of consumers. And most ovens space wildly inaccurate. Therefore they have to give instructions that give a balance between adequate curing and the an extremely real and frustrating reality that plenty of ovens will certainly be also hot and could reason the clay to burn. The accuse on the package space what is walking to offer adequate results for most consumers.

But it’s likewise common knowledge among professional polymer clay artist (who jointly bake a the majority of clay) that the strongest results come as soon as polymer clay is baked for longer 보다 the manufacturers recommend. Ns agree with this wholeheartedly. For example, the indict on packages the Kato Polyclay tell you to roasted at 300­°F (150°C) because that a just 10 minutes. As soon as I do the efforts that, the clay to be grossly underbaked and easily crumbled in my fingers. The same sized piece of Kato Polyclay baked 30 minutes come out strong and difficult for me come break. Baking polymer clay for much longer than recommended will certainly not harm it in the same way baking a loaf of bread too long will provide you a difficult brown brick. Irradiate colored clays can darken and also discolor, but they will not burn. Even if friend leave her clay in the range all work long, as long as you don’t exceed the correct temperature, it will not burn.

What Temperature need to I Bake blended Clays At?

Sometimes, particularly if you’re do something from scrap clay, you will have actually a task that includes a mix of much more than one brand of polymer clay. What temperature have to that project be baked at? I’ve never ever seen an official answer from any polymer clay manufacturer, therefore I have the right to only speak indigenous my very own experience. I constantly bake in ~ the greatest temperature needed of every the brands in the mix. For this reason if ns mix Kato Polyclay (which cures at 300­°F (150°C)) through Fimo (which cures in ~ 230°F (110°C)), i will use the higher temperature. I’ve never had any trouble with this yet.

An exception would it is in if you are baking, because that instance, the human body of a cat figurine out of Kato and also the ear out of Fimo. I’d bake the human body at the greater temperature to assure a full cure and then apply the ears and do a 2nd baking in ~ the reduced temperature.
