Borosilicate, or Pyrex, glass, was developed by Corning and is the glass that "Corningware" used to be made from...it can go from cold (refrigerator) to hot (oven) without cracking.
Coloured borosilicate glass yields beautiful, ethereal hues and is a very different palette when compared to soda glass, where most of the time WYSIWYG (what you see is what you get).
Here are some new boro beads I have listed in my Etsy shop:
Boro beads are wonderful design elements in jewellery...here's a bracelet using shades of violet with copper.
HAPPY EASTER EVERYONE!!!
