What is the difference between glass beads and Czech glass beads regular?
I am new to the scene of balls and I was wondering what is the difference, if any? All they considered vintage?
Czech glass is manufactured in the Czech Republic (or zone). There is a long tradition of glassmaking in the region, and they have a reputation for making very fine glass and crystal. Czech beads are not just a style – they may be faceted and polished, pressed, or torch. Any manufacturer can create glass beads using the same techniques, but does not Czech glass.
