Advice needed to determine if a torch is minor or major

[frillcappa]

Im looking to buy a torch from somone that has a few for sale but are unaware if they are minor or major torches. Can anyone help explain what the difference is between these clasifications, and how to determine if a torch is minor, or major?

on a side note, im looking to start blowing pyrex glass with a torch... do i need to anneal these pieces the same way as i do with furnace work in system 96?
thank you!

Majors & minors look nothing alike.

If they mean a minor or a mega minor, I think all the megas are red, no?

Look here:

Mega Minor: http://www.nortelmanufacturing.com/torches-mega.shtml
Major: http://www.nortelmanufacturing.com/torches-major.shtml
