Is the wine crystal glass “glass” or “crystal”?

With its exquisite shape, thin and transparent glass wall, crisp sound and “crystal cup kiss”, it looks like a dreamy and cold princess, and it is our common crystal goblet. However, is it made of “glass” or “crystal”?

1. Crystal cup
(1) Is the crystal cup really made of crystal?
In fact, the word “crystal” in the crystal cup comes from the Italian word “cristallo”, which means a clear and transparent goblet made by imitating crystal. The crystal cup has no crystal structure, nor can it be confused with gemstones and amethysts.

(2) Characteristics of crystal cup
The reason why the crystal cup is light, transparent and dazzling under the light is mainly due to the addition of lead, magnesium, barium and other minerals during processing. The traditional crystal cup mainly contains lead, and different countries have different standards for lead content in the crystal cup. Lead can increase the strength and brightness of the crystal cup, so the crystal cup is relatively durable despite its thin wall.

2. Crystal glass vs glass
The main difference between a crystal cup and a glass is that the crystal cup contains 2% – 30% of minerals, while the ordinary glass contains almost no other minerals. The main differences between crystal cup and glass cup are as follows:
It is worth mentioning that the progress of science and technology drives the continuous innovation of goblets. For example, the appearance of lead-free crystal glasses not only enriches the types of glasses, but also reduces the fear of “lead”, while borosilicate glass makes up for the lack of glass strength.
