1pc Heat Resistant Glass Coffee Mug with Measurement Marks - 15.22oz Capacity - Ideal for Summer Drinks and Teacher Gifts

I love this - I worked in a chemical lab, and this is great fun! Also, you can heat it on a hot plate, as you would a pyrex lab beaker, so very practical. I might buy a second one, if available!

Visually, the mug is great, but I don't know yet if it will survive boiling water, I think it will, but I have slight concerns. However, I recommend it because it is a great gift for a caffeine fan or a chemist

So nice mug! I love the fact that it's so transparent even of an unexpected size (I thought smaller) instead pleasantly surprised! Absolutely recommend
