What is the best oven for baking polymer clay?

In this brief guide, we are going to answer the question “what is the best oven for baking polymer clay” with an in-depth analysis of the different ovens you may use for baking the structures made of polymer clay.

Moreover, we are going to highlight how baking affects polymer clay, what is an appropriate oven for baking polymer clay, and what are the guidelines for temperature, time, and some tools to bake the polymer carefully.

What is the best oven for baking polymer clay?

Any oven available at your home can serve best for baking polymer clay. You can safely cure your polymer clay in a toaster oven, toaster oven, countertop convection oven, and so on by following important considerations that need to be kept in kind while baking clay. Moreover, the use of a microwave oven or curing in boiling water is not considered to provide appropriate curing.

The adjustability of polymer clay with every type of oven is because polymer clay is not very picky. It can cure well in almost all the ovens while maintaining the accurate temperature condition for an appropriate duration otherwise you will burn the clay. Therefore, it depends upon your personal preference which oven you want to use.

Baking of polymer clay:

Clay can be used to make crafts for decorating your home and different items that can be made with clay are mason jars, candlesticks, fun figurines, photo frames, and other structures. The manufacturing of these structures needs a unique process of baking that can be performed at specific temperature conditions.

The polymer clay is highly versatile and can be adjusted with every type of oven for its baking. The baking makes the clay structures hard and makes them resistant to any fall or shock that is responsible for their breakage.

Using an appropriate oven:

Though you can use any type of oven for baking, most people prefer toaster and tabletop convection ovens for curing polymer clay. For toaster ovens, their small size enables them to preheat quickly, consume less energy for operating, and be put anywhere. But it is inconvenient in a way that the space inside it is not enough to hold the clay structures of a bit larger sizes.

On the other hand, the convection ovens are considered a bit more suitable because of their larger size and even temperature distribution throughout the oven. Once the clay is placed inside and the temperature is set at a particular level for a specific period, your clay will be baked properly.

Moreover, the microwave oven and boiling in water are not considered good as they will cause uneven heating, burning, and releasing harmful gases. All these will be problematic and the best is to avoid using these two baking methods.

Temperature requirement:

The temperature conditions should be maintained properly while baking as an inappropriate temperature will cause burning or toxic fumes production. The temperature requirements for different polymer clays are different but most of the polymer clay needs to be baked at a temperature up to 350 degrees Fahrenheit and not more than that.

These fumes are of irritating chloride that makes it difficult to breathe in that area. If such a thing happens, try to leave that area immediately or open the windows to let the toxic air escape out. At low temperatures, the polymer clay will not be heated to the desired level and hardened enough to tolerate any shock or pressure and will be broken easily.


The baking time for different structures and polymer clay materials need different times for their hardening through heating in an oven. Typically, the baking time for clay ranges from 15-30 minutes where thinner structures need less time whereas thicker structures need more time to cure.

Tools for baking of polymer clay perfect:

You need different tools while baking your polymer clay to properly regulate the baking process in an oven. some of these tools are described below:

Oven thermometer:

As the maintenance of an appropriate temperature condition is one of the important factors for obtaining a perfectly baked polymer clay structure. The temperature can be better monitored and maintained through the use of an oven thermometer. These thermometers can detect temperature fluctuations which can thus be adjusted accordingly.


The timer can properly monitor the time for which the polymer clay needs to be baked.

Oven mitts:

When the polymer clay is heated, it becomes hot just like other utensils when placed on the stovetop. It also becomes difficult to hold them or take them out from the oven immediately after baking for which you need some assistance. Oven mitts serve best for this purpose that is usually made in the form of gloves and can easily hold the clay without the risk of getting hurt.


The baking surfaces for placing polymer clay can come in several options, such as ceramic tiles, shallow pans, cooking sheets, glass, or other metallic tiles. You can use any of these to keep underneath your clay.

Safety concerns for polymer clay:

While using polymer clay, you need to do some precautionary measures to avoid some of the unsafe things from happening. For this purpose, you should not eat clay and keep it safe from the children as they can accidentally or unknowingly consume it. You should also avoid crockery made of clay. Moreover, you should avoid burning the polymer clay as it can produce some toxic fumes.
