As an expensive decorative item, gemstone needs careful protection, cleaning, and unique maintenance methods. The purpose is to protect the gem from damage or discoloration. There are two main washing methods: manual washing and mechanical washing. The following is an introduction to the principles of these two methods and their considerations.
First, the manual washing method
Spread a soft cloth or a soft towel on a convenient work surface, take a small plastic bowl, hold more than half of the body temperature, add a drop of detergent, and prepare a cleaning solution with a small brush made of natural fiber. Some sharpened wooden sticks can be used to clean gemstones or gemstone materials - brushes made of plastic or nylon are not available!
Pay attention when cleaning:
(1) The soft cloth soft towel on the working surface is indispensable. The purpose is to prevent the gem material from rolling, slumping, and slotted washing tub.
(2) Detergents containing ammonia, acid, alcohol or other chemical components should not be abused, depending on the type of gem material, to avoid discoloration of the gemstone.
(3) When the stain on the gem material is to be scraped off, use a small wooden rod to cut the tip and gently scrape it off, and metal materials such as pointed hard tacks are not available.
(4) Try to use water of about 30 degrees Celsius, hot water can make the glue soft, and the gem can be protected from thermal shock.
(5) Equipped with a magnifying glass to observe the cleaning effect from time to time.
(6) The cleaned gemstone material should be placed in a cool place to dry, and should not be placed directly under the sun to avoid damage from sunlight or ultraviolet rays.
(7) Soaking is detrimental to certain gem materials because these gem materials can absorb water and cause color changes, and organic gem materials can also cause changes in the internal material structure.
(8) Before dropping the cleaning solution, pay attention to the number of gem materials.
Second, mechanical washing method
Even if it is an expert, it is more cautious to use this method, because in addition to the hazard of the wave, the damage caused by the heat is also huge. The three methods are detailed in the following:
(1) Ultrasonic washing: Ultrasonic scrubber is used to concentrate the wave energy on the solid surface of the cleaning liquid (that is, the surface of the gem material) to form a micro vacuum, which can remove dirt, wave vibration and washing caused by vacuum explosion. The increase in bath temperature is detrimental to gem materials, causing the explosion of liquids and other natural inclusions in the gemstones, although most ultrasonic washing manufacturers are equipped with special washing fluids, which shortens the operation time and avoids the above problems, but some exquisite Vulnerable gemstones cannot be cleaned in this way.
(2) Steam washing: It is very effective in cleaning metal gemstone materials, but it can cause serious problems for delicate or glued gemstones.
(3) was washed with boiling: the temperature change caused by this method is very dangerous, as this method must be washed with, first try gem material preheated and then placed in boiling water, should also be washed and dried slowly cooled. In summary, mechanical washing methods are best avoided.
Third, storage
The storage of gemstones should be lined with natural fibers (cotton, silk), etc., and should be placed separately to avoid collision with each other. The storage environment, temperature and humidity should be kept as stable as possible. Do not wear jewelry when exercising. Collisions, impacts and frictions will be damaged. Any jewel including jewelry. For swimming or other water sports, it should be noted that ammonia and other chemicals and contaminants in the water have a strong effect on the jewels, and the gems should be prevented from reaching the natural water.
4. About ivory and bone materials
The main components of ivory and bone are calcium and phosphorus and different amounts of carbon and fluorine. The organic tissue of both is collagen (a gelatinous substance), the structure has a certain directionality, and it is easy to bend in a hot and humid environment. If it is affected by water for a long time, the collagen will be decomposed, and Inorganic structures are also susceptible to erosion and become brittle due to aging in exposed sunlight. Ancient ivory is often yellow, which is considered to be a natural patina. Sometimes the color may be artificial or due to the remnants of some early decorations, the original dye on the ornament has been broken down, in this case The staining of the residue will show the imprint of the original. The evidence that the imprint is a pre-existing ornament is both interesting and valuable, or the stain can indicate the location of the early attachment or ornament. Removing these dyes will result in important features. Loss, so consider these possibilities before starting your work.
Summary: The methods described above are more professional maintenance methods, which can effectively protect jewelry and keep the color of jewelry in a better state. These methods of physicochemical properties are preferred methods. These methods are recommended for jewellery requirements.
