Crystal glass has a long history. In ancient times, due to many impurities in glass raw materials, the melting temperature is not high, the glass is not melted well, and there are many defects such as unmelted sand particles and bubbles. At the same time, there are many colored metal ions such as iron, manganese and titanium in the raw materials. It is opaque or translucent. In the 13th century, the Venetians used quartzite with less impurities and Levant's sodium-containing plant ash to melt into a colorless, transparent glass.
In the 15th century, the quality of the raw materials was further improved. With the pure quartz sand in the lower reaches of the Ticino River and the soda ash recrystallized from the aqueous solution of the ash, the transparency of the glass was significantly improved compared with the past. Similar to the crystal, it was named Cristallo. The composition range (mass fraction) of soda-lime crystal is  SiO2 70.0%~71.5%, Al2O3 0.8%~1.31%, CaO 4.07%~4.72%, MgO 1.47%~1.66%, K2O 2.84%~4.55% , Na2O 15.2%~16.8%, Fe2O3 0.25%~0.51%, MnO 0.26%~0.51%, SO3 0.19%~0.31%, Cl 0.62%~0.92%, P2O5 0.15%~0.24%, Fe2O3 and MnO in this component are Impurities in mineral raw materials, Cl, P2O5 are all impurities in the ash soda ash.
