What can Crystal be used for in glass?
Crystal is commonly used to make glassware and ornamental items with dramatic cut facets that accentuate the prism-like properties of the glass. Lead glass has high viscosity meaning that it can be worked at low temperatures. This allows manufacturers to produce particularly decorative and elaborate designs with this material.
Which is the best description of a crystal?
Crystal. Crystal, or full crystal, is a glass that has greater than 24% lead-oxide (PbO) according to a European council directive established in 1969†. This is a heavy glass with a high refractive index and high dispersion of light. As such, it is traditionally valued for its clarity, weight and sparkly appearance.
How much lead is in crystalline crystal glass?
Consumers commonly perceive crystalline and crystal glass as being lead-free. However, this is not necessarily the case as these products can contain more than 10% lead oxide according to the standard. It is common for manufacturers to state a product is crystalline or crystal glass without any disclosure of what materials they contain.
How to find out how much my crystal glassware is worth?
Check with crystal replacement sites or companies to establish the value of your crystal. Once you have identified the manufacturer or the pattern, you can check to see what it would cost for a replacement piece, which also lets you know the piece’s overall value.
