Collection: Crystal Glass
There are three main types of crystal glass which are:
Lead Crystal Glass- contains at least 24% lead in the glass mixture, making it softer and easier to cut intricate designs without breaking. This glass in most cases is about 0.25” thick. It also produces a rainbow effect when set in direct sunlight in addition this type of glass has a distinct bell-like ring when tapped lightly.
Crystal Glass - does not contain lead and is typically thinner than lead crystal glass. It can come in various shapes such as drinking glasses, vases, and bowls, etc. and/or may not have acid etch designs on it. When purchasing crystal glass, it is important to consult a knowledgeable dealer who can differentiate between lead crystal glass, crystal glass, and other types of glassware. Lead crystal glass the maker or manufacture can sometimes be identified be by the pattern cut into the lead crystal glass, while crystal glass may lack identifiable markings regarding of its origin or maker.
Rock Crystal - is named as rock crystals because quartz crystals is add to the glass mix which has the similar appearance and weight as lead crystal or crystal glass. This Glass is amorphous and doesn't have a crystalline structure. As such, calling glass a crystal is something of a misnomer that is accepted due to long established traditions. Ornamental items may be made from real rock crystal such as quartz but these materials aren't particularly suited to hollowware such as glasses.
