Pyrex glassware for safe oven cooking

Can You Bake In A Glass Bowl

You cant bake in the glass bowl. Why? Because glass doesnt heat up quickly, but if once heated, it retains the heat for longer. Additionally, this much heat activates the Double action baking powder.

Ideally, you can use light-colored metal pans for baking. As metal is the best heat conductor, this property makes the baking process rapid. On the contrary, glass is not an efficient heat conductor, and batter baking takes long. However, if you are interested in over-bake brownies, a glass pan is a good choice because its center takes longer to cook thoroughly.

How To Identify Pyrex Glass

Is that vintage dish you’ve got your eye on at an estate sale is Pyrex? It looks like it, but how can you be sure?

When Corning introduced Pyrex in 1915, they began using what is known as a back stamp to identify their products. A back stamp is a logo on the underside of a piece of dishware. In the case of Pyrex, the back stamp is often raised instead of stamped with ink. This makes the back stamp impervious to years of washing.

Dating your vintage Pyrex can be a little trickier, but it can be done. Pyrex experts have identified what range of years a Pyrex back stamp will take on a certain appearance. The logo might look a little different from year to year. Sometimes, Pyrex would use a certain color combination around their back stamp to signify years of production.

Pyrex dishware explosions are a common phenomenon. Hundreds of people have complained online due to the shattering of the dishware.

Most people claim that the explosions started when Pyrex changed its material composition from borosilicate to soda-lime. Though the statement is true, this is not the main reason.

The main reason why a Pyrex material explodes in an oven is due to thermal shock. Thermal shock happens when you move an object rapidly from cold temperatures to hot temperatures. The result is a crack in the material.

The original Pyrex material was resistant to thermal shock. See, soda-lime glass has an expansion and contraction rate three times higher than borosilicate glass. Thats why most people prefer borosilicate glass instead of soda-lime glass.

How To Use Pyrex In The Oven Safely

When using Pyrex glassware, the key is to avoid thermal shock.

Thermal shock occurs when a breakable material, like glass, is exposed to a drastic temperature changethe sudden shift from hot to cold or vice versa results in competing pressures across the surface area.

When Pyrex glassware is exposed to radiant heat, like that of a heating oven, the side of the glassware closest to the heat source grows hot while the inside and other parts further away from the heat source remain cool.

Pressure begins to build as the differing temperatures exert stress on the material, which can lead to the glass shattering into pieces.

Exploding glassware incidents are not only dangerous but extremely messy and hard to clean up. To avoid such a disaster, preheat the oven before you put your Pyrex glassware inside. A preheated oven has a uniform temperature therefore, radiant heat wont stress one side of the glassware.

Additionally, make sure your glassware has reached room temperature before heating it. You should never place glassware directly from a refrigerator to an oven.

Another situation that could cause thermal shock is when cold juices drip out of the food onto the hot glass. To avoid this, pour a small amount of liquid in the bottom of your Pyrex glassware before putting it in the oven. The liquid will act as a buffer and lessen the likelihood of shattering or cracking.

Never place hot glassware directly onto a countertop, stove, sink, or damp towel .
