I will second Dusty's thoughts on the ventilation.

A box fan is no match against the wind out side pushing back against it.

And the winds is mostly unpredictable.

It is your health and your decision but if you get as addicted to molten glass as I am you could put your health at serious risk breathing and touching combustion products as well as a lot of hazardous minerals used to color the glass that get vaporized in the flame and then settle out of the air as dust that gets everywhere that then gets on your hands before you go make lunch.


End of soap box rant.
