Why are there differences types of glasses for different types of wine?
user
There are two main reasons, actually.  One is that some wine glasses are designed to concentrate the flavor of the wine, which is what you want to do when drinking a relatively strong wine like a cabernet sauvignon.  The other reason is to avoid oxidation, which can spoil the flavor of wine.  I think in many cases wine glasses are glass because they’re designed to diffuse light, which may avoid the oxidation, and also to filter out UV rays.

That is interesting, what type of glass should I use for red wine?
user
I think either the tulip-shaped wine glass or the straight-sided Champagne flute, both of which have a rounded top with wide bowl.

This is more of a design question than an actual concern about safety, which might change based on what you’re trying to do.  I’d suggest avoiding “glass”, but perhaps a plastic container would be better.
