To get glass to flow along mandrel you need lots of heat and you usually have to "move it" with marvers or tools...

And as for getting glass to flow, remember "earth sucks", the amount of heat and the way you move rod or wind of glass on mandrel will always move the molten glass down.... You have to counter that movement by centrifugal force or by rotating rods or mandrels at correct speed so gravity exerts equal force around molten glass glob...

The laws of fluid dynamics always work on glass when it is in its molten "plastic" state....

Thank you very much!
