Does Porcelain Crack Under Heat?

Porcelain is a type of material made from clay, and it is used for many different home decor and home furnishing products. Porcelain is a material that has been used for centuries.

Porcelain is a highly durable clay fired at very high temperatures, so it is often called “high fired porcelain.” Because it is fired at such high temperatures, it is tough for porcelain to crack or get damaged due to heat.

Porcelain And Heat

Porcelain is considered to be high-fired clay. Porcelain is usually fired at above 2300°F. Many people call it high-fired porcelain because it is fired at high fire temperatures.

Because porcelain is fired at such a high temperature, it is a heat-resistant type of material. For porcelain to crack, it would need to be in a temperature that is higher than 2600°F, which would be extremely high temperatures.

All kinds of porcelain, even porcelain tiles, can withstand high amounts of heat. It is considered a very durable material used for home decor accessories, lamps, or even tile flooring.

Porcelain Is The Highest Fired Type Of Clay

Porcelain is the highest fired type of clay around, especially when compared to stoneware or earthenware. This high fire nature makes it an ideal type of clay to use for many kinds of products. The high-fired nature also means that it is highly heat resistant.

There are three types of clay typically used: porcelain, ceramic, and earthenware. Of all these three, porcelain is fired at the highest temperature possible.

Below is some information and comparisons about these three types of clay and firing temperatures for each.

Porcelain Firing Temperatures

Porcelain is usually fired in a kiln anywhere between 2200°F and three 2600°F or 1200°C and 1400°C. This makes it a highly high-fired kind of clay. It also means that it is extremely heat resistant and extreme.

Kaolin is the material from which porcelain is made. Kaolinite is a clay mineral and is the substance that is used to make this very hard and translucent material known as porcelain.

Stoneware Firing Temperatures

Stoneware is what most people refer to as pottery. Stoneware is fired from 2100°F to 2372°F, or between About 1200°C to 1400°C.

Compared to porcelain, stoneware is not fired at as high temperatures, but it is still fired at a very high temperature. If you have a stoneware item, it should not crack unless exposed to heat higher than 2372°F or 1400°C.

Earthenware Firing Temperatures

Earthenware is an iron-rich type of clay that can be fired at low temperatures between 1300°F to 2120°F. Of all three of the clays, earthenware is the one that breaks the easiest and has the lowest temperatures in the firing process.

Porcelains Heat Resistance Properties

Porcelain is the highest fired degrees of heat from all three of these materials. Porcelain, stoneware, and earthenware materials should all withstand heat, especially if put under hot water or even placed in an oven.

It would be extremely difficult for porcelain to be damaged by heat. You can usually put a very hot pot of boiling water on a porcelain surface, and it will not scorch or damage the surface.

It also means that porcelain is extremely heat resistant and a very durable type of material. It would be really hard for porcelain to crack just under heat.

How Porcelain Can Crack

Even though heat is a very hard way for porcelain to crack, there are ways that porcelain can crack. Porcelain can crack when porcelain tiles are put on a floor, and the tiles are not level, so the tiles can crack under stress.

If you have porcelain tiles on a floor and the subfloor is not stiff enough, so there is a lot of movement on the floor, the porcelain tiles can crack due to stress, wear and tear. Porcelain has an average breaking strength of 275 pounds, so if heavy objects are put on a tile floor that has movement, the porcelain tiles can crack.

When placed outside, porcelain tiles are tough and naturally weather-resistant, even in freezing weather. As porcelain does not absorb water, it will not crack due to the cold. Porcelain is an ideal material to use for flooring and tile because it will not be cracked due to extreme heat or crack due to extreme cold.

Other Ways Porcelain Can Damage

Porcelain does not usually damage due to heat or cold, but there are other ways that it can get damaged. Most of the ways it is damaged are due to misusing or not understanding the porcelain tiles.

Here are some ways that porcelain can get damaged:

A selection of abrasives.
  • Bleach – Bleach or ammonia-based cleaners have also been known to hurt porcelain or hurt the grout that is used between the tiles. We recommend that you use soap and water to clean any of your porcelain, including the grout or between the porcelain tiles.

Porcelain is a very durable and tough material that is high-fired clay. Porcelain is an ancient material that has withstood the test of time.

Porcelain can withstand extreme heat. That is why if there is a house fire, porcelain will often even be able to withstand extreme heat and fire. 

Porcelain can even be used to create 3 D products. Watch our video below to see how 3D porcelain is made using technology in a factory in China.

Earthenware, Stoneware, And Porcelain Materials

Earthenware, stoneware, and porcelain are all made by various clays and then fired. The kind of clay used and the temperature they are fired at can make a difference as to how soft or hard the actual end product is. Though they can all seem to be similar, they are all very different materials and products.

3-D Porcelain Manufacturing, All You Need to Know

Brass and bronze are both copper alloys, but brass is copper and zinc, and the bronze material is copper and tin. They both look similar but have different properties and uses. When brass or bronze is made into home decor products, many times they will be sand cast or use a lost wax or investment mold technique. Each of these production methods has different uses and prices that can affect the overall production.
