I was thinking about how to slump a large diameter tube from a flat plane of glass. I have little experience with glass working and dont know to what degree this is workable...
You'd take a piece of float glass, from like a window and slump it over a ceramic tube you made/found as a form. Put it in the kiln and let it soften and after its really gooy pull it out for a second and use poles to roll the hanging edges together. The maybe flip it so the seam is on top and put it back in the kiln.
?Is this at all how you would form a large diameter tube from found resources? What size kiln do glass workers usually have; what is the widest sheet i might be able to work? can it be anealed in the same kiln it was slumped in?
thanks!
