I feel like I am bombarding this forum and I apologize for that. So I bought a glass Pyrex baking dish assuming because the brand was Pyrex that it would be able to handle the heat. I used it am I hot plate hey to catch any potential overflow to protect my beaker. Of course it shattered violently. Trial and error, lesson learned! Luckily my Beaker landed on the hot plate standing straight up. So my question is, what can I use to transfer the heat from the hot plate to the beaker? I cannot find a corning bakeware, is there anything else that is just as good?
