Glass plates can be used to cover food cooking in a pan to prevent overcooking
If you want to use a glass plate as a lid, it is crucial to ensure that the glass is oven-safe or heat-resistant. Look for markings on the bottom of the plate indicating its suitability for oven or stovetop use. Pyrex, borosilicate glass, and tempered glass are examples of heat-resistant glass that can withstand higher temperatures without shattering. However, even with heat-resistant glass, it is essential to avoid extreme temperature changes. Always preheat your oven before placing glass inside, and avoid moving hot glassware directly from the oven to cold water or a cold surface.
Additionally, the type of stove you have matters. Using a glass plate as a lid is riskier with a gas stove, as more heat escapes up the sides of the pan. Electric stoves are relatively safer in this regard. If you have another pot or pan available, it is better to use that as a lid instead of a glass plate. Alternatively, consider investing in a universal lid that can fit multiple pans.
If you decide to use a glass plate, it is important to exercise caution. Ensure that the plate is the right size and fits securely on top of the pan to minimize the risk of shattering. Always supervise the cooking process and avoid extreme temperature changes to reduce the chances of the glass breaking.
In summary, while glass plates can be used to cover food cooking in a pan to prevent overcooking, it is essential to prioritize safety. Always use oven-safe or heat-resistant glass, avoid extreme temperature changes, and be cautious when using glass around direct heat sources.

Glass plates are not recommended for direct contact with a stove due to the risk of shattering
If you are considering using a glass plate as a lid for a pan, it is important to understand the risks involved. Glass plates are not designed to handle the same levels of heat as cookware. Placing a glass plate directly on a stove or over a pan can cause it to shatter, creating a dangerous situation with hot glass shards and potentially ruining your cookware. Even with a simmer plate, the glass plate may not be able to withstand the heat and could still shatter.
However, not all glass is created equal. Some types of glass, such as borosilicate glass, are more heat-resistant. Borosilicate glass is used in scientific lab equipment and some kitchenware, like certain Pyrex products. These types of glass are generally safe to use on a stove, but it is important to check the specifications of your particular glassware before using it over direct heat.
If you find yourself without a proper lid for your pan, there are safer alternatives to a glass plate. You can use a sheet pan, a pizza pan, or even a frying pan of a similar size to cover your pot. These metal alternatives are better at handling heat and can act as a makeshift lid in a pinch. Another option is to use a double layer of foil or parchment paper, which can provide a tighter seal to trap heat and moisture effectively.
In conclusion, while it may be tempting to use a glass plate as a quick fix for a missing lid, it is not recommended due to the risk of shattering. Glass plates are not designed for direct contact with a stove's heat source. Instead, opt for safer alternatives like metal pans or foil/parchment paper to cover your cookware and prevent dangerous accidents in the kitchen.
