Brent's in AZ.
He should talk to Brent in FL. (Mr.Smiley)
Smiley (Brent) torches boro OUTSIDE so doesn't have the huge ventilation setup--that would save him some $ initially if he's gonna do boro.
Of course there *are* loads of us doing soft glass on a *budget* with fans--I found my smaller fans pass the "incense" test quite nicely--I don't do enamels, I don't do fuming, I don't do *any* 00 frits, or anything "powdered"--I stick to the stuff that's basic, but for PPP & my little hothead, it's sufficient--and I JUST GOT TO MOVE INSIDE!!!
(I've been "outdoors only" for the last long while!!)...now I've just got to get the torch set up! I was waiting to get the fans in & try the incense testing.
