I'm looking for ways to manipulate molten glass with (e.g. bending a heated glass tube).
This article mentions that oxides tend to adhere, hence molten glass to heated stainless steel.
What materials could I use to manipulate hot glass? Perhaps I could coat the glass or instrument doing the manipulation with some sort of powder or liquid?
The glass is soda lime glass which has a transition temperature of 550 degrees C, so the temperature it needs to cope with will be a fair bit above that.
