## Questions & Answers

**Q: How much does this weigh please? I would like to use it in a fermentation pot, if it's heavy enough. Thank you**
A: I can't weigh mine, as I dropped it last week and broke it.  Haven't yet ordered another.  However, it must have been heavier than a metal one I got, which weighs 35 g but isn't heavy enough to rattle loud enough to be heard unless you're right near it.  Perhaps the sellers could tell you.  If the weight is critical, it might be worth finding out how much the Pyrex version weighs.  It's more expensive but might be heavier: https://www.amazon.co.uk/Pyrex-450B0005040-Classic-Milk-Watcher/dp/B000UO7GHQ

**Q: Is this food grade glass.  ie. no hidden nasties lead etc.**
A: Maybe I am too trusting but there are laws these days about "adulteration" of products used for food, e.g. saucepans

**Q: Can I use this product in a microwave?**
A: Why not?  It’s glass and you microwave things in glass bowls ... so no problem...

**Q: can this be used to stand a pudding basin on when steaming a pudding**
A: No, it is meant to alert you that a liquid starts to boil by rattling. It is not flat enough to put a pudding bowl over it steadily.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Does what it says on the tin

### ⭐⭐⭐⭐⭐ No more spilled milk
*by C***E on 11 June 2025*

Works well

### ⭐ Lasted 3 weeks. Not fit for purpose.
*by C***N on 2 January 2025*

This item worked perfectly for 3 weeks, used only for boiling water in a small pan. One morning, still in the bottom of the pan, I found it had developed a fracture that nearly split it in half. Very disappointed and would not recommend this product. I think the problem is that the glass is too thin and not substantial enough, unlike the original Pyrex ones; therefore not fit for purpose. I have written to the manufacturer.
