Pouring boiling water is quite risky as it might lead to a steam burn or scalding. Another thing to keep in mind is what type of material you are pouring in into. If you have a porcelain sink, it is likely to crack due to the heat. All in all, pouring boiling water down your drain will only cause issues down the road.
Generally, porcelain will melt or break when you subject it to temperatures above 1600C. This temperature is attainable when you expose porcelain tile to direct heat, such as that of a fireplace. Direct exposure will cause the porcelain to crack, melt or even explode.
Because it is fabricated in high heat over 2000° F, porcelain can easily hold its own against hot kitchen or bathroom environments. Its surface is resistant to damage after exposure or contact with hot pans and pots and won't burn, smoke, or emit harmful substances.
Sudden changes in temperature cause localized thermal expansion, this produces tension and compression that easily cracks most ceramics.
These cracks usually form when the tiles are weakened due to the cut – either partial or multiple – and especially where they are cut to form the corners or edges. Technically – anything which interrupts the continuity of the material can make these places more fragile and very delicate points of the tile.
One of the most common causes of hairline cracks on porcelain sinks is thermal stress. Considering porcelain is usually layered on metal (which conducts heat), the sink loses heat rapidly and can become very cold—even when the room isn't cold.
These can appear for a number of reasons, but ultimately time will be what makes them worse. It could take months, years or even decades for a crack to really become pronounced in your porcelain! In kitchens (and some bathrooms), temperature changes can be a major culprit in the formation of porcelain cracks.
How do you fix a hairline crack in a ceramic mug? Apply super glue to the crack and hold it in place for 1-2 minutes. If there's a small gap in the crack, press both sides together. Use the applicator tip of the super glue to apply the glue directly into the crack.
So, porcelain is able to manage well as ovenware. Typically, porcelain ovenware dishes are suitable for temperatures up to 500-572F (260-300C).
Even regular ceramic materials, such as tiles and bricks, are able to withstand very high temperatures. Technical ceramics are manufactured with extreme heat resistance in mind, making them very suitable for high-temperature conditions.
Porcelain is less likely to crack under extreme heat, whereas ceramic can become damaged, cracked, or even change shape when exposed to extreme heat.
Porcelain tiles tend to be harder, more resilient and more stain-resistant than ceramic tiles. They are one of the easiest types of tile to maintain but their surface can eventually be eroded by the regular use of corrosive chemicals such as ammonia, bleach or acids that can also damage the grout and loosen the tiles.
The major difference between porcelain tile and ceramic tile is how it's made. Both tiles are made from a clay mixture that's fired in a kiln, but porcelain tile is made from more refined clay and it's fired at higher temperatures. This makes it denser and more durable than ceramic tile.
First, put the piece on a flat surface, such as a tabletop. Then give it a little tap. “If it rings it's probably fine,” Lackey says. “If it's a dull sound, it means you'll want to look a lot closer.” That dull sound usually — although not always — will indicate a crack or defect.
Porcelain tile is highly durable. Because it is extremely hard and dense, this tile resists wear, scratching, chipping, and cracking. That makes it an exceptional choice for homes with pets and active children.

Ideally, your cooking utensils should be made of an inert substance that does not chip, peel, crack, vapourize or dissolve. Plus, the substance should be a good conductor of heat for the food to cook uniformly. Porcelain is durable with no metal leaching into the food and thus can be a great option for cooking.
The clays used in the manufacture of porcelain tiles are denser than the clay used in ceramic tiles. This makes porcelain more porous, hence they do not attract moisture easily. As a result, porcelain is more heat-resistant than ceramic.
Porcelain tile generally gets hotter than concrete pavers or natural stone. So if your surface is in an area that gets a lot of direct sunlight, choose a lighter color tile to avoid burnt feet! A cream, beige, or light gray porcelain will be less prone to absorbing heat.
Cracking is mainly caused by uneven drying of the piece, meaning that some parts of the pottery shrink more than others. The key to avoiding these pitfalls is to create a consistent environment for drying the piece and undertaking the necessary preparation to ensure that the entire piece dries at a similar rate.
In general, cracks result from stresses in the clay. There is always some stress in clay because of the fact that it shrinks as it dries and when it is fired, and it also expands and contracts during firing. Sometimes the stress is too much for the clay to handle and it cracks.
Crazing refers to small hairline cracks in glazed surfaces that usually appear after firing but can appear years later. It is caused by a mismatch in the thermal expansions of glaze and body. Most ceramics expand slightly on heating and contract on cooling.
What is crazing? Crazing is the effect on pottery which causes it to have a web of tiny cracks over its surface. These are not cracks in the actual structure of the pottery but actually an effect on the glazed part of the pottery.
Hairline cracks often can be patched with a porcelain epoxy. Larger cracks or cracks that penetrate fully through a bowl usually cannot be repaired, requiring that the toilet be replaced.
