How did the ice crack come about?
There are two main causes of ice cracks: natural and artificial.
1. Natural ice crack is naturally that turquoise is squeezed by surrounding rocks when forming veins, impacted by crustal pressure, and deformed during crustal movement. These are inevitable and unpredictable.
2. Man-made and man-made ice cracks will occur during the mining and processing of turquoise. Let's talk about mining first. Turquoise is mined in a mine. In the past, it was either fried with heavy machinery or directly with explosives. These effects can be imagined, and the raw materials of turquoise are more cracked. In addition, processing, especially raw ore processing, whether cutting, carving or polishing, will have an impact and cause ice cracking.
What kind of turquoise cracks easily?
Everyone knows that porcelain is used to refer to the hardness of turquoise. The higher the degree of porcelain, the more brittle turquoise is, and this material is more prone to ice cracking. Judging from the summary of the current product market, the high porcelain pine with military green, military yellow or brown has a smaller chance of ice cracking, while the high porcelain blue or high porcelain pine is slightly higher than others.
Is the ice crack of turquoise easy to find?
Ice cracks are common in raw ore turquoise. Ice cracks are often fine lines as thin as hair, without big cracks. If you don't observe it carefully, it is often difficult to find it. Therefore, I often hear friends in the circle say that the materials told by the merchants are beautiful, but consumers only find cracks in the existing thin ice when they buy them home. After all, workers may not be able to see turquoise when it is processed in the factory, and merchants may not be able to check everything with a magnifying glass when they bring it back.
What's the relationship between wire and ice crack?
It doesn't matter.
Obviously, these are two different things. Iron wire is a mineral collection related to the natural growth of turquoise in geological strata! The wire is thick and thin, loose and dense. And ice cracks are one kind of cracks. Don't confuse the two.
Natural iron wire looks like a crack, but it is not.
Is ice cracking acceptable? Is ice crack a quality problem?
In fact, ice crack is not a quality problem for processors and sellers. After all, ice cracks are very common. As we all know, raw ore turquoise is always watered when it is processed, in order to avoid the structural instability and cracking of turquoise when it is polished by universal machine. Now that all protective measures have been put in place, ice cracks will still occur, which no one can do.
Whether it can be accepted depends on the degree of ice crack and the aesthetic requirements of consumers. Ice cracks as thin as hair will not have potential safety hazards and will not deteriorate when worn normally. At first glance, it is obvious that large ice cracks are a great safety hazard. Some consumers can't accept any natural flaws and can only wait for the truly perfect material.
Will the ice crack disappear after playing?
Once the ice crack appears, it will not disappear, but the longer it is worn or played, the turquoise will be moistened and patinated, so the body fat secreted by the human body will wrap the ice crack layer by layer, and the ice crack is invisible. Therefore, friends can rest assured to play. It can be considered that the ice crack has been "cured". It didn't really disappear, but it was out of sight.
What maintenance measures should be taken at ordinary times?
The "three taboos policy" to avoid high temperature, exposure and collision is applicable to almost all jewels and jade, so I won't repeat it here. Turquoise has a subtle problem: fear of drying. Therefore, it will often be soaked in water during maintenance. If you play with the perfect patina, you can soak it once after a long time.
It should be noted that turquoise placed in dry air for a long time will lose water seriously and will inevitably crack. Sudden immersion in water or slight collision will cause turquoise to break and even crack. Therefore, you can't soak in water immediately. You can spray the water spray for watering the flowers a few times to let it absorb, and then soak the water.
