A couple of questions for you to help us understand:
1. When you say 'work far out in the flame', do you mean at the very tip of the outside cone or further?

You are smelling Nitrogen Dioxide. It is building up in your workspace and can be dangerous. It has the characteristic bleach smell.

You need to improve your ventilation soon!

I know Devardi makes some but I've heard all their glass is sub-par quality and can be very shocky in the flame.

Sounds like your flame chemistry is reducing the glass.

Oxygen concentrators run at lower psi than regulated tanks. Most tanks run 15psi O2 but an oxycon will usually put out around 5psi. Some...

Just a guess, but sounds like you're fuming the silver too heavy. Try for a light "piss yellow' silver fume and then bake it into the glass using a reducing flame before working. Then back worked...

Sounds like mixed COEs.
Seems more likely to happen with soft glass rods vs boro.

If not that, maybe poor quality glass like Devardi or similar. I've heard they can be a nightmare to work with.

Electricians often use an 80% limit rule of thumb.
A 20A circuit operating at 80% would provide 16A safely.
Using your 14A kiln, that would give you a nice little 2A margin, which at 120V is about...

You may be referring to cabochon mandrels. They have a round disk on one end but may look like a T from the side. An actual T mandrel I haven't personally seen.

Since the torch was the only thing that changed, maybe try "lowering" the torch. That might be an easier job than raising everything else up higher.
