How To Cook Clay
You can cook your clay in an oven. First, you should reheat your oven according to the clay’s instructions. You can place a piece of paper on the ceramic tile inside an aluminum pan. Place your project on the top of the paper and then close the pan. Bake your clay for about 30 to 35 minutes and let it cool.
Create designs using either hand-sculpting or molding, and then bake clay in a 275-degree oven for an hour. It may be convenient to bake clay in stages so that any damage is not done to the ones that have been made before. The larger your clay model is, the longer it will take to bake, and depending on your designs shape and thickness, your bake times may also vary. Your packaging should give you a good indication as to how long your modelling clay is going to bake.
To figure out your correct bake time, just use your clays average baking time as listed in its instructions. No, I looked up my clays average bake time, which was Sculpey III in my case, which has a baking time of 15 minutes. To find out the right times and temperature measurements for each clay, you will have to bake some test pieces.
The directions on the packaging should give you a sense of which temperature to bake each clay at, and for how long to keep it in the oven. Read the directions on your clay packaging to find the baking temperatures and determine what type of oven you will be using. Read the instructions on the clay package to preheat your oven at the specific clay temp. Before placing the sculpture into the oven, be sure that the oven is preheated at an appropriate temperature.
Even though the general temperature of your oven stays right where you have it set, each time you turn the heating element on, it will shine red hot, which could squeak through your polymer clay pieces if they are too close together. The radiative heat of a hot element may burn your clay, as I already stated, but there is also a problem with your items being able to set without having their temperatures remain hot all of the time. Too low of a temperature, and your clay will break; too high, and the exterior will fuse together and burn before the interior has cooked. You cannot burn or damage polymer clay from baking it very long, even hours, if you keep your temperatures right.
| Steps | How to Bake |
| Pre-heat your oven | Between 230°F and 275°F. |
| 14 Inches thickness require | 15 to 30 minutes of baking |
| Thinner clay takes | 15 minutes to cure |
Polymer Clay does not dry or get stiff from leaving it in the open, but when storing it, then you need to keep it away from heat sources and direct sunlight, otherwise your clay will partly cure and thus be unusable. If you have a mold or wire within your polymer clay, you can just pop it into an oven with no problems. Unlike foods that will burn if left too long in the oven, polymer clay does not burn when baked at the right temperature. It is not recommended that you use the microwave when baking polymer clay, because it does not heat evenly — thus, some parts of your polymer clay project will start re-curing correctly, and others will stay softer.

Polymer Clay, also called Polyclay or Fimo, is a modeling material you can either curing or baking in a normal oven at home. Polymer clay is a plastic modeling compound that comes in a variety of colors, can be formed into just about any shape, and can bake to a permanent solid in a home oven. This model clay stays soft and malleable, meaning that you will be able to use it for a lot of craft projects down the road. Another brand of modeling clay that dries out by baking it in your normal indoor oven is Laguna OvenCraft Clay.
Stuffing with polyester, shaping aluminium foil, holder boards, or a baking rack with beads from Sculpey(r) can help keep your clay projects shape as they bake. While this modeling clay dries naturally, you can accelerate this process by placing it in an oven. Lay out your completely formed clay pieces onto a parchment- or cardstock-lined baking tray, then tent the pieces with a piece of foil, or with the pan. The parchment or simple cardstock will create a protective barrier between your clay and your baking sheet.
Gather your baking sheet or clay tiles, parchment paper or plain cardstock, aluminum foil, and an oven temperature gauge. The clay tiles will regulate your oven temperature, while the paper keeps the clay away from your glazed tiles. When you put unglazed clay onto a ceramic tile with glaze, then bake, the places where the clay touches the tile will shine. A piece of clean paper will not burn at 130-140C, and will prevent the clay from becoming glossy on surfaces touching the base.
Rebake for 15 minutes at 275 degrees F. Then, add the third full layer, add your finishing details, and then rebake for the last 15 minutes at 275 degrees F. Overbaking will darken your clay, while burnt baking will create bubbles and blackening. For best results, I recommend baking a piece at least 30 minutes for every 1/4 of a inch thick. If you get to the end of the recommended bake time and you feel that your piece is still slightly undercooked, then to avoid burning, take it out of the oven and let cool.
Bake the clay for the recommended time, which is usually between 15-30 minutes per 1 1/ 4 -inch thick. It is recommended to initially bake the thickest pieces for 15 minutes, then bake them an additional 5 minutes, then an additional 5 minutes, etc. The clay needs at least 15 minutes to properly cure. If you are not using the clay pots frequently, and mold forms over long periods of storage, simply wash it out with hot water, then brush it off with baking soda. Either count this continued use in the cook time, or remove both the lid and food shortly after you take your clay pot out of the oven.
Providing this will help to prevent sticking of your clay, as well as avoid touching a cookie sheet you might be using for preparing the food afterwards. It sounds easy, but baking to set your polymer clay can be the most frustrating part of making a clay project.A Do not worry; you can set your polymer clay confidently, as long as you follow some easy safety precautions. Over time and frequent use, your clay vessels will become darker, retain marks from burning and stains, but will develop a charming patina.

How long do you bake clay?
Pre-heat your oven to the recommended setting recommended by the manufacturer, which is often between 230°F and 275°F. Each 14-inch thickness requires 15 to 30 minutes of baking, and thinner clay takes 15 minutes to cure. When adequately baked clay has cooled, it can be scratched with a fingernail without the impression sinking in.
Why did my clay explode in the oven?
Steam occurs when water reaches 212°F. The item explodes due to the pressure of the steam and the lack of an escape route. You run the danger of having your greenware burst if it is very moist, especially if it is damp inside of empty air pockets in the dirt.
How can I harden clay without an oven?
When you don’t want to use the stove to melt muds that harden at a certain temperature, you may use an intensity weapon, hair dryer, or intensity embellishing device that has been heated to the right temperature. Place the polymer earth creation on a piece of ceramic tile or a block of wood that won’t stick.
