This Pyrex brand glass measuring bowl is excellent for working with chocolate. We do all of of our tempering and pouring using this bowl and highly recommend it to all of the home chocolate makers out there or for small business uses. Glass absorbs heat pretty well so that is why it is so helpful for tempering and pouring. Using aluminum bowls is fine too but metal conducts heat very quickly so you may find your chocolate cooling off too quickly before you have poured all of your molds. Below I have listed some of the specifications shown on the Amazon listing.
