CERAMIC IS FIRE RESISTANT Some floors can withstand fire… as long as it is put out immediately. But ceramic does not contain plastic and is fire resistant. We use fire in our homes for cooking and heating, but it has always posed a safety risk if it propagates away from the kitchen hob or the fireplace.
Stone and brick generally hold up well in fires. Porcelain, glass, and ceramic items also tend to be resistant to heat. Unlike metals, however, they can be fragile and may break during a house fire under falling debris or a collapsed wall or ceiling.
But ceramic does not contain plastic and is fire resistant. Using ceramic tiles for the splashback behind the hob or on the floor around the fireplace protects the surfaces from hot saucepans, spilled hot liquids and sparks.
Fired ceramic does not withstand thermal shock nearly as well as other materials like steel, plastic, wood, etc. Ceramic is hard and resistant to abrasion but it is brittle and propagates cracks readily.

Abstract: In contrast to organic fibres, ceramic (inorganic) fibres, are not flammable and can maintain their physical strength and thus structure at very high temperatures. They find applications in very high temperature environments (>1000 °C).
Kitchen ovens don't get hot enough to fire pottery. You can always pit fire clay at home, but it's quite complicated to set it up and even more difficult to achieve the specific temperature needed for specific kinds of clay. If it's too hot your clay will melt and if it's not hot enough it won't dry properly.
Most types of clay are fired successfully within the temperature range of many kilns, which is 2000°F and 2400°F, apart from porcelain, which requires higher temperatures.
If trapped water freezes in ceramic, no matter how miniscule the amount, it will expand and can break the ceramic. The reality is, it's impossible to ensure that zero amount of water will invade the small nooks and crannies that exist in all ceramic objects.
For example, a ceramic tile has the ability to withstand temperatures of up to 1,800 degrees Fahrenheit before it begins to crack. However, stone tiles can withstand temperatures of up to 2,300 degrees Fahrenheit before they begin to break down.
Organic matter in the clay is burned and oxidized to carbon dioxide, and fluorine and sulphur dioxide from materials in the clay body are driven off at 1292–1652°F (700–900°C). At this point the biscuit firing is completed. The clay particles are sintered or welded together.
In the event of a fire, ceramic will not burn. Fully vitrified tile is literally born in fire. The long, hot firing strengthens and hardens the ceramic. When fully vitrified ceramic tile encounters high temperatures, it absorbs the heat slowly throughout its thick, uniform body.
Ceramic is fire resistant.
Surrounding these spaces with ceramic tiles is an effective way of improving safety thanks to their fire resistance. Using ceramic tiles for the splashback behind the hob or on the floor around the fireplace protects the surfaces from hot saucepans, spilled hot liquids and sparks.
Standard firing times for various kiln sizes are: Small earthenware kilns: 8-12 hours. Medium earthenware kilns: 10-18 hours. Large earthenware kilns: 14-24 hours.
Advanced ceramics work at temperatures way above standard ceramics that are clay based , these are typically in the region of 650C, and advanced ceramics are considered up to 2200c and then specialist ceramics classed as UTC or ultra high temperature ceramics operate above that temperature band but these are rare ...
Heat Resistance to Withstand Extreme Temperatures
1,220℉), alumina Fine Ceramics only begin to melt or decompose at temperatures above 2,000℃ (approx. 3,632℉).
Ceramics are typically hard and brittle. While their strength in compression is very high, they are not suitable for loading in tension. Their brittle qualities mean that they fracture very easily. In compression, a crack is not easily propagated, but in tension the crack is free to grow.
Water can dissolve or deform ceramics that have been low fired, i.e., at temperatures around 600°C. Ceramic fired at high temperatures may also have water-soluble mineral constituents, for example gypsum or calcite. Additionally, water may carry solutes that damage ceramics.
Ceramic will expand under high heat and then contract as it gradually cools down. Thermal shock is when this change in state happens suddenly or too quickly.
However, it's important to remember that kitchen ovens have their limitations. They don't get hot enough for glazing, and their lower temperatures mean you can only work with certain types of clay, like paper clay or salt dough. The final product will turn out somewhat fragile due to the lower firing temperatures.
Glass and ceramic are surprisingly resilient and are often much easier to save than fabrics. After a small house fire, the only damage to your glass belongings may be a coating of soot. However, ceramics can be porous and may be susceptible to staining from smoke damage and hard water.
In lacking a Small Pottery Kiln, another method of firing pottery at home is through gas firing. This method uses a barbecue gas grill or a gas burner as the heat source. Be sure to use low fire clay for this method to ensure successful results.
Yes, you can fire clay pottery in a campfire, but it requires careful monitoring and control of the temperature to achieve sintering without causing fractures.
