At one point or another, all of us have tried putting glass plates in the oven. Whether you are trying to bake something or heat some leftovers, it is a convenient method that can deliver quick and efficient results.
Now, you may be asking, can you put a glass plate in the oven? Yes, you can put a glass plate in the oven. However, this only applies to tempered glass, and certain products can only take so much heat (up to 350 or even as high as 470°F) before shattering.
That said, this begs the question, which plates are oven-safe and which aren’t? Be sure to keep reading as we delve deeper into this question.
Oven-Safe Glass Plates
Oven-safe heat-resistant glass plates have been around for a while. Though it often comes as a surprise to most, these plates were first introduced to the market as early as the 1900s.
Their earliest versions were Pyrex pie plates. Soon enough, it would take the world by storm because of their sheer convenience.
In the early days, these oven-safe plates were made from a material called borosilicate. However, there were some glaring problems with borosilicate that eventually pushed most manufacturers to stay away from it.
The main reason for this shift was the way borosilicate glassware breaks into dangerously sharp shards of glass.
Nowadays, the main material for oven-safe plates is known as soda lime. While not yet completely shatter-proof, these oven-safe plates will break into large, dull pieces when dropped – effectively solving a major safety concern.
Needless to say, glass plates have come a long way since they were first introduced. After all, there are now several types of oven-safe glass plates that you can get.
With the evolution of heating methods and the emergence of the microwave, you can now choose between oven-safe, toaster-safe, and microwave-friendly plates.
How to Determine If Your Glass Plate Is Oven-Safe
In most cases, it is as simple as reading the label. This is because manufacturers will often leave a label on the base of the plates themselves.
Specifically, these labels can often be found near or at the center of the plate’s backside. Be on the lookout for the following labels:
- Oven-Safe – As the name suggests, these glass plates can be safely put in the oven. However, remember that despite this certification, manufacturers often place recommended temperature limits on their products. More often than not, the limit is placed in the 300-350°F range, but some can go up to 470°F. Again, we recommend that you check out the plate’s safety recommendations.
- Microwave-Safe – This means that this plate can be subjected to microwave radiation without being damaged or becoming extremely hot. In fact, it is safer to use properly tempered and microwave-safe glass than paper plates in the microwave.
- Toaster-Oven Safe – These glass plates take it even further. This is because the direct heat used by toaster ovens is altogether different from the heating methods used by traditional and microwave ovens.
The importance of the guidelines as indicated on the plate’s label can’t be overstated. Remember, while some are glass plates are oven-safe, this does not necessarily mean that they are also safe to use on toasters and microwave ovens.
Moreover, the rule also works both ways, as microwaveable plates aren’t necessarily oven-safe.
As you may have figured out by now, not all plates are safe can be safely put in the oven. Moreover, unless you take the proper precautions, even oven-safe glass plates may still break. So, you must use them properly.
Identifying Non-Oven-Safe Plates
Now, it is time that we delved deeper into the question. Again, the label at the back of the plate should tell you all you need to know. So, we highly recommend that you only place glass plates in the oven if they are labeled as oven-safe.
Conversely, you may encounter glass plates labeled as “decorative.” These plates are purely ornamental and should be used for decorating your table only.
This means that under no circumstances should you place them in the oven or even serve food off of them.
Remember, most of these decorative plates have a glazed finish that isn’t food-safe. Oftentimes, they may contain lead and other chemicals that may prove dangerous once heated or ingested.
Similarly, glass plates made from canary glass can have traces of uranium and emit radiation. Once heated, they become especially dangerous. So, be sure to keep these glass plates out of the oven.
That said, there are certain glass plates that bear no such label. These can include everything from vintage plates, artisanal plates, and imported plates.
Take note that vintage and antique plates pose a special risk. Similar to canary glass, some older glass plates may contain radioactive materials that are altogether dangerous to your health.
In addition to the potential dangers of food poisoning and exposure to dangerous chemicals, there is another danger that comes with heating these glass plates in the oven.
This is concerning the way the plate itself will react to rapid heating and cooling. In all likelihood, the extreme changes in temperature will result in damage to your plate, as it can crack, shatter, or explode.
