What is that grainy sandy-rock thing they were rolling the glass in?

[corningmuseumofglass]

It's crushed colored glass. It melts onto the surface of the hot clear glass and adds color to the piece.

@corningmuseumofglass

so do you put like dye in it?

It didn't look orange at all...

@cammigurlgonewild

the colorants are metal oxides that heat to a certain color, like "blued" steel per se. the grainy sandy stuff in the question above is actually glass with the colorants added at the premelted stage where it is the minerals batch that will be melted down, so its never actually clear glass, just color thats crushed up

How do they stop the spread of diseases though spit on the tubes?

In our studio courses and with our staff demonstrators, we provide alcohol wipes and ask that people use these after blowing into the pipe. You'll see numerous signs posted with this reminder.

In our public Make Your Own Glass experience, we provide disposable cardboard mouthpieces for each visitor, as well as alcohol wipes. In addition, we put the ends of the pipes in the 2300 degrees F glory hole as needed.
