Loyalty in the Time of Tyranny Chapter 66

Lingzi stone, also known as dolomite, is mainly composed of calcium magnesium carbonate and is a common mineral.

In Adrian Tang's memory, dolomite was abundant in later generations and not uncommon. But in this era, dolomite is no longer so common. The first reason is that no one needs to use this ore. In this era, the role of ore is not only to smelt iron and make porcelain, but also to make pigments. Dolomite cannot be used to smelt iron, nor can it be used to make ceramics, and it is even more unrealistic to make pigments.

Without market, there is no demand.

Second, it is difficult to find dolomite veins with relatively high purity.

With the production technology of this era, if you want to use dolomite to produce glass, the purity of the raw materials is extremely high. Even if the purity is reached, it is difficult to produce completely transparent glass.
