Easy : How to recognyse a quality Crystal
How to differentiate a crystal from a piece of glass and how to check the quality of the crystal? Here are some explanations that will help you to see things more clearly. . . . and learn more. Crystal is of absolute clarity, its manufacture requires a much more elaborate technique than that used for glass. It is the result of an alchemical operation in which the mixture of potash, silica and lead, brought to a melting temperature of 1450°C for 36 hours, seems to be lost in the fire to be reborn like a phoenix.
Unlike glass, crystal contains lead oxide, 30% for its superior qualities, allowing greater clarity and refraction of light, which gives it an incomparable shine, easy to observe with the naked eye. Do the test yourself, in contact with a ray of sunlight, the crystal will break down the spectrum of light like a rainbow, unlike glass, which will remain greyish.
It is also easy to work with and makes it possible to produce crystals with original, complex and fine shapes, which once polished, increase their refractions to light.
