Crystal glassware originates from Europe, and its main producing areas are Germany, France, Italy, Eastern Europe, Czech Republic, Hungary, etc., each with its own characteristics. Crystal glass is made of silicon (Silica) and lead oxide (subsequent lead-free crystals are made of other materials such as potassium oxide yttrium oxide, etc.). Each factory has its secret recipe, which makes the crystal shine especially. The clarity is Care about the quality of the polishing technology.
Those containing 24% lead or more are called lead crystals, and those below 24% are called lead crystals. The benefits of adding lead are heavier, textured, more transparent, clear and bright; the disadvantages are softer and easier to grind, so the more lead is not necessarily the better. However, modern people are paying more and more attention to the concept of environmental protection, so that the production of crystal glass also penetrates into environmental protection elements. The new lead-free and flawless crystal glass is extremely flexible and crystal clear, and is twice as safe as ordinary crystal glass.
