1.What is the Lead crystal ?

The history of crystal dates back thousands of years to the Mesopotamian times. Lead oxide was used to enhance the brilliance of glass as used today, but applied in differently. This was an alternate to the popular rock crystal which was more expensive, harder to cut and less refractive.In the year 1676, George Ravenscroft revolutionized the methods of adding the lead oxide, which brought lead crystal a major step closer to it’s mass production of today.


Lead crystal :Glass is a mixture of mostly silica, sodium oxide and calcium oxide. In lead glass, however, the chemical lead (II) oxide (PbO) is added. The amount of lead can vary, depending on the glass properties desired and the intended use.


Lead crystal be large used for drinking glasses and serving dishes, as well as sculptures, miniatures, jewelry, chandeliers, candleholders, Christmas ornaments, and Home décor items.


Some types of lead crystal can contain up to 33% lead, so you will want to use caution when drinking or eating from your crystal. Acidic food and beverages, such as pickles, fruit juices, wine, or soft drinks, can leach significant amounts of lead from the containers they are stored in. Research has proven that lead exposure can cause forgetfulness, memory loss, nausea, depression, fatigue, joint pain, vomiting, and abdominal cramping. High levels of lead exposure can even lead to sterility or brain damage.


More people now realized lead exposure damage,and refused the lead crystal,other side as manufacturer of crystals ,we must bear duty of protect our environment,and follow our govment 's requirement not allowed to processing the Lead crystal.so we going to Optical crystal
