When substituting a Pyrex dish for a metal pan, reduce the oven temperature by 25 degrees Fahrenheit
Pyrex baking dishes are made of glass, which has different heat conduction properties compared to metal. Glass is an insulator, which means it slows the flow of heat between the oven's air and the batter until the glass itself heats up. On the other hand, metal is a better conductor of heat, heating up and cooling down more quickly. As a result, when substituting a Pyrex dish for a metal pan, it is recommended to reduce the oven temperature by 25 degrees Fahrenheit. This is because the glass dish will brown the sides and bottom of the food faster than the interior cooks, increasing the risk of over-browning.
Additionally, glass dishes are not ideal for intense heat or extreme temperature transitions, so it is important to avoid sudden temperature changes when using a Pyrex dish. For example, do not place a hot glass pan on a wet or cold surface, as the rapid change in temperature can cause the glass to shatter. Instead, use a fabric dish towel or potholder to protect the glass from thermal shock.
