It is very interesting that natural pigments will darken after heating, which is called burnt limestone, but because of the different degrees of firing, they are divided into thick and light mouths, etc., and some minerals are temporarily fired, that is, although they will turn white when heated, when the temperature drops back to normal temperature, they will return to their original color.

As for some natural minerals, such as cinnabar, because the ingredients contain mercury, although they can be fired at high temperatures, they are generally not used to fire because they produce highly toxic gases. There are many kinds of firing methods, and the differences in methods and techniques will also cause various differences in hair color. This technique is also common in ancient paintings.

In addition, the acidization method can also cause discoloration of some natural minerals, but you must be familiar with chemistry in this method, otherwise it may also be dangerous.

There is also a sloping alley. The lifting tool has a wheel, and the mining tool has a bronze curved blade axe.

The tube well is drilled and chiseled with a circular blade file. This is a newly invented percussion ring file, which strikes the bottom of the well and crushes the rocks. Once filed, re-lifted, and then a second pause. This cycle repeats itself and makes a deep well.

"Whoever has been taking coal for a long time can distinguish the color from the surface of the soil, and then dig it. As deep as five zhang Xu, the coal is obtained.

Or a well down, the charcoal is wide and horizontal, and it is wide and wide with it. It has a support plate on it to prevent the ear from collapsing. ”
