glass getting bubbly

[meadowesky]

I started working some more today and when I am using clear along with some other colors it gets these little tiny clusters of bubbles. Am I burning it?
My ox is on 7 and my gas is on about 4. I dont have the torch cranked at all. I am using a minor. This is my second day with it so I am pretty new to using the minor. Any suggestions? Thanks

Could be a number of things, but first thought is it's just the Moretti clear bubbling up on you. It's notorious for doing that. Don't know of much way to avoid it.

Well the blue did it too. Are my ox prop. settings okay? Should I lower them? It seemed like the farther out in the flame I got the less bubbles I got but also the longerrrrr it took to melt it.

A weak flame is one that doesn't have enough force behind it to make it burn straight. It curves upward. This causes the face of the torch to overheat and erode. found this on arrow springs and that is what my flame looked like. could that make bubbles?

You are probably just working it too close to the face of the torch and getting it too hot. For soft glass on a Minor, I work about 3-4" from the tip.
