The most expensive glasses are typically made of either a metal or plastic material.
While the metal ones tend to be cheaper than the plastic ones, the metal is often harder to work with and often requires more time and energy to make.
Glass is also a durable material that can be used for years without breaking, which is one of the reasons it’s the cheapest material in our list.
But the price of glass beads can also be a factor.
Glass beads are often expensive because of the manufacturing process, which takes more time, and the glass itself is often made of a cheaper material, which means it takes longer to wash and polish, according to the American Glass Association.
But if you can get your hands on a cheap glass bead, you can save yourself a lot of money.
