Borosilicate glass, sometimes referred to using the trade name Pyrex, is a material that is particularly suitable for use in contact with food substances.
Its advantages include chemical inertness, transparency and heat resistance, making it ideal for use as a material for cooking utensils.

However, glass is not a good thermal conductor, a characteristic that limits its use in traditional ovens or in the microwave. Unfortunately, glass is fragile and not very resistant to sudden temperature changes.
