Is glass Pyrex safer than plastic for mixing hot batter?
Based on 1 peer-reviewed studykitchen
Verdict: Safer
Yes. Glass is chemically inert.
What's actually in it
Pyrex and similar tempered glass mixing bowls are inert to food. They handle oven, fridge, and microwave without releasing chemicals. Plastic bowls aren't as forgiving: hot batter, melted butter, or boiling syrup pulls additives and particles out.
What the research says
A 2025 study in J Agric Food Chem documented plastic particle release in hot conditions. Glass is the clean baseline.
Invest in a set of tempered glass mixing bowls. They stack, last decades, and handle every task.
