How to use Pyrex bowls in the oven

Pre-heat the oven before placing your Pyrex bowl inside

Always pre-heat your oven before putting your Pyrex in to cook your food.

I contacted the Pyrex team and they stated that the reason you need to pre-heat the oven first is because ovens will release an extreme amount of heat to rapidly bring it to the desired temperature often releasing more heat that the maximum you are reaching.

The direct and extreme heat from the oven heating up can cause thermal shock to the Pyrex dish causing it to crack or break.

When Pyrex is put into a pre-heated oven the temperature is increased slower and more evenly.

Cover the bottom of the Pyrex bowl with liquid before cooking meats and vegetables

Adding liquid to the bottom of the Pyrex dish before adding meat and vegetables will help to regulate the temperature of the glass. This will stop any sudden increases in temperature which can shock the glass making it more brittle.

Adding liquid to the bottom of your Pyrex bowl will also stop the food from sticking to the bottom without the use of oil or butter making your dish even healthier.

Add a small amount of lasagna sauce to the bottom to prevent the lasagna sheet sticking.

Avoid putting Pyrex bowls directly on a burner or under a broiler

Pyrex bowls should not be placed on a burner or under a broiler because of the sudden heat change. The Pyrex glass is not made to withstand sudden temperature changes so avoid doing this to keep your Pyrex bowl from breaking. The key with Pyrex is to make sure it has gradual temperature changes rather than sudden.

Never put your Pyrex bowl on a boiler or straight onto your stove.

Put hot Pyrex bowls on a cloth or pot holder and not directly on your bench

Placing Pyrex bowls on a pot holder or cloth will help it to cool more gradually and also prevent any marks on your bench. The Pyrex Borosilicate glass will quickly want to release heat out and the cloth can help to absorb the heat released.
