They are called sliders because a hole is created through the glass where thing is used to hand them. Fibre paper is used during the firing process to create a hole - the paper is rolled up tightly and placed on the base glass (where you want to hole to appear). A piece of glass is then placed over the top of the paper and the piece is fused.
Fibre paper is specially formulated for kiln use and will not burn away during firing. It is also used to line the kiln shelf to protect glass from sticking to it.
I have put the pendants on leather thong - it really suits them. They will be added to my website later this evening.
Just a reminder - I am exhibiting at Boharm Hall during the North East Open Studios annual event. The hall is open daily until Monday 21 September. There have been quite a few visitors already, which is encouraging.
