How is colored crystal made?

However, not everyone knows that in addition to the traditional transparent, there is still an unusually beautiful and spectacular colored crystal, which is obtained through the addition of various metal oxides into the glass. They give the crystal unusually noble shades of red, purple, blue, green and pink colors.
