Anyone heard of the spot annealing hype train?

Had a thought some time ago on sealing an object in tubing that wouldn't survive a trip through the oven. Why not anneal the mostly finished tube, drop in the material, seal and anneal only the new end portion.

Maybe a sleeve with small elements and insulation or mod a curling iron? Could also try pulling the seal to a thin point as thin glass requires less time and lower temps.
You can bend stringers with a Bic, so perhaps a zippo flame anneal for those with the skill and a polariscope(sp?).

Not sold on the theory... Surely there are those who know the numbers and can figure equipment parameters for a brief soak and scaled ohms.

Feasible, or impractical?

Adam D (I think) has sealed a vial of his own piss and someone else sealed a french fry.

I've sealed a dead wasp in a vial. Done just as you say, except with no anneal after closing up the capsule.

Careful what you seal in, lol!

oh man, I wonder if the gasses from the decomposing mouse would be enough to burst the glass.

As you said, anneal the main project and then just seal it up. If you start adding elements to heat one part of the glass but not the rest, all you're going to do is introduce more heat inconsistencies and stress. Do what you can to limit the work on the project post-kiln, and call it good. I think with this kinda thing, you're pretty much left with "do what you can, and hope for the best"

It was a rat and it did blow up, Ask Trevor, it was his project and mess to clean up, lol

So then, what of a rod half sticking out of a kiln and being annealed. Would there be a dividing section around halfway that has stress where the rod was full annealed before?
What then if you relieved yourself on the middle section? Would you be less stressed?
