Process of Casting silver Jewellery
A two-step process, investment casting, produces small, complex shapes. Most castings, especially large ones, are made in sand molds. Permanent metal molds are used to make many small, simple parts; shell molding gives greater accuracy for a large volume of semi precision parts.Molten silver is poured into the cavity and allowed to solidify. Sand, mixed with a binder to hold it together, is pressed around a wooden pattern that leaves a cavity in the sand. Wax or plastic replicas of the parts are molded in accurate metal molds. Top of the line casting equipments are utilized to produce the silver jewellery. When the whole mold is heated, the replica melts, leaving behind a cavity into which silver is poured.
Taking care of gemstones
Steam cleaning is quite effective but can result in thermal shock because of the often-quick temperature change. It can result in cracking because parts of the stone are forced to expand at different times. Most gemstones can be immersed in a solution of mild detergent and warm water.Likewise with pearls; although soaking can result in discoloration, so this should always be avoided. After soaking for a few minutes, gently clean the stone with a soft brush. Pearls should be dried after cleaning, using a soft towel, and air-blown dry. Extra care should be taken to remove dirt from the bottom of the setting, a common place for build-up to occur.
