Turquoise maintenance method introduction :
Turquoise has a harder hardness than water and is very susceptible to wear. It is chemically unstable and will be dissolved by corrosion when exposed to acid. Turquoise is particularly discolored at high temperatures, and even a long period of exposure and soaking in sweat will also discolor the turquoise. These must be taken care of during the wearing and collection process.
Most turquoise has holes that absorb hand oil, lip balm and perfume, although in traditional Chinese crafts, the turquoise surface is coated with a layer of paraffin to increase the color of the turquoise and protect it. The role of turquoise, but should still pay attention to sweat, oil, etc. when wearing, to avoid excessive contact with cosmetics and skin oil, so as not to damage the gem. Due to the porous porosity of the turquoise, it is important to avoid the use of heavy liquid to measure the density when identifying, because tribromomethane and diiodomethane will discolor the turquoise. The turquoise color is delicate and afraid of pollution. Avoid contact with tea, soapy water, oil, rust and alcohol to prevent the pores from penetrating into the gem.
Turquoise is afraid of high temperature and cannot be directly fired and exposed to direct sunlight to avoid fading, cracking and cracking. Long-term exposure to large sunlight can cause cracks and fading of turquoise due to water loss. Too high temperature baking will make the turquoise crush and brittle. Some Indian handmade jewellery is beautifully made and the repair costs are expensive. However, silver has a high thermal conductivity. When repairing silver jewelry, the temperature is difficult to control, and the turquoise embedded in it will be broken due to excessive temperature. Because those stones are bonded to metal materials.
Turquoise hardness is not large, should avoid collision with other hard-wearing jewelry or items when wearing. Do not put turquoise into the ultrasonic cleaner. On the one hand, the turquoise with holes will absorb the solution to fade itself. On the other hand, when it is ultrasonically vibrated, it may be in contact with other jewelry, whether it is a hole or a dense turquoise surface. Damaged.
Some turquoise imitations and Indian fake jewellery work rough and cheap, but repairs are very difficult, even impossible.
