Will glass explode if I boil it

Great! Share this article  

If you've ever been in the kitchen, you've probably heard a window or drinking glass break. For all the times I've dropped dishes, glasses and bowls on my floor, only once did I get to see what happened when they broke. The result: flying shards of glass that could have injured anyone standing nearby. The good news is that most cases of broken glass don't end this way—but it does happen from time to time. So how can you prevent shattering your glassware?

Yes, glass can explode when heated.

Glass is a brittle material. It will break when stressed, and it's not very good at withstanding stress. Glass also doesn't conduct heat very well: It's poor at conduction, meaning that it transfers heat slowly through its structure; this makes it a poor insulator. That leads to another problem: Because glass forms weak bonds between molecules, it's also poor at conducting electricity. You may have heard of this phenomenon before—it's why electricians often use plastic instead of metal to insulate wires.

So there you have it—glass can explode if heated enough because it's a poor conductor of heat and electricity, which means the thermal energy from your boiling water has nowhere else to go except into shattering your kettle into pieces!

Glass ovenware can explode if it is heated on the stovetop or in a microwave.

Glass is a poor conductor of heat, so you have to be careful when heating and cooling glass that you don't trap any water vapor inside the glass vessel. This can cause an explosion as soon as you put your hot glass into cold water. In addition, because glass heats up unevenly, there's always the possibility that part of your container will be much hotter than another part (which will cause thermal shock), causing it to explode.

Drinking glasses can get too hot and break, though it's rare.

If you drop a glass and it shatters, that's because the glass was already weakened by the impact. A sudden temperature change can also cause glass to break, as can rapid cooling or heating due to exposure to cold or warm water/air/etc.

When a glass breaks because of temperature stress, it's called 'thermal shock.'

Glasses are made of a lot of elements, but the main ones are silicon and oxygen. In order to be glass, those two ingredients have to be combined in an exact way. When you heat up or cool down a glass too quickly, it can get stressed—and that can cause thermal shock. Sometimes this is called "glass fatigue."

Thermal shock happens when you heat or cool your glass too quickly and it's not able to adjust while its molecules change their position and shape. This usually happens when you put something hot into cold water; your dishware will crack because the sudden temperature difference causes stress on the surface of its molecules (a kind of internal tearing). It’s also possible for thermal shock to happen if you put cold glasses in hot ovens (or vice versa), which essentially causes them to expand faster than they would normally expand if they were at room temperature.

If glass isn't uniformly stressed or cooled, pieces may break off and fall into your dish.

Glass is a brittle material that can shatter if not handled properly. When you're making something in a pot of boiling water, it's important to keep an eye on how hot the liquid is (and therefore how much stress it's under) so that you don't accidentally ruin your meal by dropping something sharp into the pot.

If you try to heat glass in the oven or on a cooktop, it likely will crack or shatter.

Glass is a poor conductor of heat, so your glass will not heat evenly. If you're heating it in an oven or on the stovetop, it's also likely to crack or shatter due to thermal shock. Glass has a low melting point and boiling point (about 1,600°F). So when you boil water in glass containers, the temperature inside can get very high before the entire container reaches that temperature. This causes thermal stress and often results in cracking or shattering.
