Gonna ask before I search. Doe's anyone know of a tutorial on this that is not on Facebook? It's very interesting to me, but I don't really I understand it yet without reading a 'tute.
Thanks Sig....!
Well if just a double seal, I can figure it out. But it seems to me to rely on negative pressure between two sealed ends. just need a few words related to that to get the gist.
I've only done a handful, but I basically just blew out a little round bottom, like a mosquito bite where I want to attach the two together (on each one), bent them close enough to each other to touch, and heated the two of them together. A little puff, and they start to make a "regular shape", and then i would heat, and puff a little. Eventually, the wall gives, and you have a seal, and then heating the seal up and puffing it out would add wall weight and make it consistent. The first few times i tried it, the round bottom part was too thick, so i had to heat it REALLY hot, and it took a few minutes of trying before the wall opened.
AI is correct. the name for this seal traditionally is the deeter seal. but apparently micah evans did one said jesus that shit worked....and now everyone calls it the jesus seal.

this piece used 6 Dieter (jesus) seals to make. the most important thing i find is that the 2 bubbles you blow to connect need to be about the same wall thickness and where they connect should be alittle thinner. controlling the heat base is important as well, blow the 2 bubbles so they are close but do not touch let cool a second and then just heat where they will connect and blow them together, the thinner the membrane the easier it will be to make the weld disappear and appear as one piece of glass.

I really, really don't want to be that guy...but it's Dieter :P there's other names for it, too.
There's an british scientific glassblower here in town and she said they call them god seals in the old country.
I've heard membrane and blow out seal as well
