"Laizhou Qing" Stone Cuts Crystal Stone

When a stone factory in Laizhou cuts the "Laizhou Qing" stone, it cuts out a piece of crystal stone. The maximum crystal column height is about 5 cm.

At the Laizhou Guolin Stone Factory, owner Wang Songjun took out a stone with several rectangular transparent stones with water chestnuts that shine like glass. Wang Songjun said that this stone is exactly the same as the image of the crystal stone on the Internet. The largest crystal column is about 5 centimeters, and the bottom of the stone is the common “Laizhou Qing” stone.

Wang Songjun said that when they were cutting a piece of “Laizhou Qing” stone, they would have cut a stone 60 centimeters high and it would have only taken 15 minutes, but this time it took an hour and a half to cut the stone and made it harsh when cut. The sound, the meter tripped from time to time. Wang Songjun finds it strange that by removing the cutting tool, he discovered that the stones were mixed with a few crystal clear stones, and the surrounding area had been “bited” to a hole 40 cm in diameter. According to experience, Wang Songjun thought that this was probably a piece of crystal stone. Immediately check the relevant data and found that the characteristics of the crystal stone described in the data were basically in accordance with the stone that he cut out.

“Laizhou does not produce crystal stones. I have never heard of any stone factory digging out crystal stones. I have been dealing with stones for eight years. This is the first time.” Wang Songjun said that this stone is from the nearby Laizhou horse. Digging down the hill, the stone weighs about 6 tons, which is a common stone.

It is reported that most of China's crystal stone is produced in Donghai County, Jiangsu Province. The hardness of the crystal stone is "7", and the hardness of the "Laizhou Blue" stone is about "3". It is no wonder that the cutting machine of the stone factory cuts so much trouble.
