Unbreakable Glass Measuring Cup, Measuring Cups For drinking, Baking and Cooking, 1000ml (35oz) Multipurpose Measuring and Tea Cup, For Cooking and Beverage Use

I've been using one of these for a few years, buying a second as I know I'll eventually break it. Well made. BUT do not rely on the gradation markers. Using an accurate kitchen scale - and knowing that 1ml of water weighs 1g - when I have 450g of water in this the scale shows 425ml. Fine for a kitchen but very much not labware. Not taking a star away as it's not sold as labware.

So far, absolutely love this. I drink out of it microwave. I’m scared to try it on the stove, but I’m thinking about it. You can go from cold to hot although I don’t stress it but it’s lightweight easy to handle. I’ve dropped it once and it didn’t break as nice as a glass feels you think it would break immediately but it didn’t. It’s great. I love it.

It will break

OK TO BUY. Price is a little high. Be sure you understand what size 500 ml is. You might want the 1000 ml instead.

I had purchased 1 before "Unbreakable" glass Measuring cup. I loved it and my sister saw mine and really liked it too. So, I purchased one to be delivered at her house on her birthday. When she opened the package the "unbreakable" Glass Measure was in a miriage of tiny broken pieces. She returned it promptly. So, my problem is that there was no Glass Measuring Cup replacement to her and ultimately No REFUND to me. What should I do?

Fits nicely under my pour over funnel, and pours neatly into my cup and thermos. Although not incrementally marked in ounces, the marks match most of my containers. It’s borosilicate glass, light in weight and the handle appears very secure.

Excellent

I dropped, it broke
