Glass cups warning.

Hello from the home of Morellis.
Yes, they still use the glass beaker, but it is in a metal holder, with a metal handle.
I was taught, when pouring hot water in to glass containers, to include a long metal spoon, as this conducts some of the heat away.... it could even be true..

I had a set of them and after a similar mishap-they've gone into the recycling.

Not sure what to think as I understand that all pyrex dish's are heat proof,and IF you break or smash them,advice that you don't put them in the glass recycling box as they don't melt as they are made of hardened glass.
This goes back again that you should never throw warm or hot water over a frozen windscreen,as it may crack the windscreen.
I have never heard of any windscreen being broken by throwing warm or hot water over a frozen windscreen.
My thoughts is that you NEVER throw warm water over the windscreen,this is to safeguard any one walking by. Eventually the water will freeze again,Which could mean some one(it could be a relative or friend) visiting, ending up falling down and possible breaking an arm or even something worse. Think of your fellow citizens

Lovely Morellis in Broadstairs. Also there as a young teen. In fact in there from a 5 year old.

I seem to remember their glass beakers came in a metal holder.

Maybe your glass cup had developed a crack in it without you knowing Mum2three. Go
Glad you didnt scald yourself, but it must have been a shock.

Brought back memories of the George Clooney ad for me!

That could have been very nasty mum2three

Definitely a lucky escape mum2three. Your post brought back memories of sipping frothy coffee in Morelli’s, as a young teenager.
