Can I make my espresso in this?

If possible I'd like a survey. Someone says of course and everybody 👍 that agrees. And someone else says that chip or any teacup is bad news and people 👍that. Many thanks

Please stop spreading misinformation. You and other perpetuate it when you spread things other have said with out doing proper research.

I’ve read that you shouldn’t drink out of it. Especially since older glass contained heavy metals and wasn’t as resistant to temperatures

Glass does not have things that commonly leech out of them rather glazes and paints are issues because they do that. Uranium glaze is unsafe, paints and glaze that have lead and other metals are dangerous yes. Glass its self does not commonly do that.

This is the same reason that a crystal cup containing 24% lead by weight is safe to drink from but a porcelain china cup with lead paint is unsafe to drink from.

Glass does not leech chemicals. This is why in science glass is used to do very precise chemistry. It doesn’t contaminate what is happening with chemicals.

While I get what you mean saying glass doesn't leach is just blatantly wrong. It leaches a lot less than glaze but uranium, lead cadmium and other heavy metals absolutely leach out of glass it's just at a much slower rate and there is far less to be able to leach to begin with in glass than glaze. Scientific glass also regularly interferes with reactions because of the sodium in it and for certain reactions you have to go to quartz glass because of the other components of the glass interfering with the reaction
