Testing bubble powder

There are too many techniques and too little time…

Most glass suppliers sell bubble powder, but don’t list the chemicals used. But if you search long and persistent enough then you find some information. 

I tested some today to see how much or rather how little is needed to create bubbles. I used float glass in my microwave kiln. Can’t wait to combine it with coloured glass…

I forgot to take a ‘before’ photo of the baking soda.You really have to use very little of any of the chemicals.

Always make sure you work in a well ventilated room when using your kiln.
