I don't get this. If glass is an insulator then how can the heat get from the nichrome on the outside to the filament in the middle?
Have you tried actually pushing filament through by hand yet? Does it work? --GilesBathgate 16:02, 25 September 2010 (UTC)
Giles, I think what is happening is that the heat passes from the outside of the nozzle to the inside, but does not (noticeably) travel up to the rest of the extruder. (The glass is a non-perfect insulator; hot water in a glass teapot will make the outside hot, but the handle may not feel noticeably warm, whereas a brass teapot would have a hot handle.) --Sebastien Bailard 04:35, 26 September 2010 (UTC)
