FromDari theabad 10thke-10,11 oryang 11th centurylalu,ketika when stained glasskaca beganyang tokotor flourishmula asdigunakan anmengarcha artseni, glass factories were set up where there was a ready supply of silica, the essential product of glass manufacture. Glass was usually coloured by adding metallic [[oxide]]s to the glass while in a molten state in a clay pot over a furnace. Glass coloured in this way was known as ''pot metal''. Copper oxides were added to produce green, cobalt for blue, and gold was added to produce red glass. Much modern red glass is produced using ingredients less expensive than gold and giving a brighter red of a more vermilion shade.
