My wife is a glass artist and she trained me to do a few things so that I could assist her, but it wasn’t until I took a class for beginners that I really learned to blow glass.

I’d say having experience in a glass studio before learning to blow helped. If you can get into a studio to at least watch someone blow glass before you try it yourself, you’ll be ahead of the game.

Also have reasonable expectations before you start. Very few people get good quickly at glass blowing. Unless you know someone with a studio it will probably also be very expensive to learn to blow glass. The studio where my wife rents time charges $160 per four hour slot.

It takes time to get used to the heat, the nature of glass, working with other people, etc…
