Gold is, without a doubt , one of the most appreciated metals for jewelry. It is a metal with golden or yellow tones that melts at an average temperature of 1062 ºC. Its degree of purity is measured in carats. The most prominent and the one with the highest purity is 24 carats, which is equivalent to 1000 thousandths of purity. Throughout this entry, we are going to discuss how a jewelry store works with gold. It is an exciting process, since, thanks to it, highly coveted jewelry is achieved.
You will learn what processes this metal goes through until it is taken to a jewelry store. For the meta to be worked, it must reach temperatures above. The percentages of the metal are chosen scrupulously to reach the ideal proportion and work it later. Once melted, it is poured Industry Email List into a mold to create the ingot . Through the pressing rolling and finishing rolling phases , an attempt is made to reduce the thickness of the piece. Cold rolling cycles are used to smooth the ingot and form a long sheet, which can measure several meters. However, it is only possible to measure thickness in microns. Some professionals use the hammer press to do this job with greater precision.
The thin sheet, measurable in microns, is cut into square pieces the size of a stamp. They are placed inside containers or molds, in which the mixing process is carried out . Different mechanical hammers hit the pieces to further reduce their thickness. At this time, experts cut the metal with a double-edged knife called a “carretto.” Even if the years pass, this phase of the process must always be carried out by hand and according to the ancient tradition of the craft. The pieces are folded on tissue paper booklets.
The characteristics and alloys of goldIf we compare this metal with other more common metals, one of its defining features is that it maintains its shine for a long period of time after being polished. Gold analysis machines offer a very accurate estimate of its quality, which is why it is so valuable in jewelry stores. Furthermore, this metal combines wonderfully with others widely used in goldsmithing workshops, such as copper or silver. The alloy highlights the beauty of any jewel, as it embeds a brilliant shine in the color tone. Let's look at some of the main alloys that you can find in jewelry stores.
They are obtained after mixing the gold metal with palladium. This alloy impregnates the piece with a whitish tone. To make the white type , originally, a secondary material was used, nickel. However, today, this combination is rejected by most establishments due to the allergological characteristics of nickel. In addition, nickel hardened the pieces, so they often ended up cracking and breaking over time.
Therefore, palladium has been the solution in recent decades when working and setting the highly coveted white gold. According to current regulations of the European Union, since 2000, nickel alloys have fallen into disuse. Other metals that make an appearance to obtain white gold are silver and copper. The main disadvantage of palladium is its manufacturing cost, since it is an expensive metal. However, it allows the piece to be highly resistant; In addition, it gives it a grayish and yellowish color. To carry out the technique, it is common to use rhodium baths , which enhance the brilliance of a white very similar to platinum.
These metals are in their pure state and are very malleable. However, unfortunately, they are also extremely soft. For this reason, it is not common to see yellow gold in jewelry artisan work. Yellow is usually worked in measurements of 750 mm (that is, 18 carat sterling ). To guarantee this proportion, 32% copper is linked to the base material. Thanks to this alloy, the piece obtains greater hardness and flexibility. Of course, the resulting color tends towards reddish tones.
These are jewelry with qualities superior to washing. The thickness of these pieces reaches a purity of 10 carats , which is three times the thickness of washed gold. Electroplating work is requested by customers who intend to purchase durable jewelry, which can be transferred from generation to generation. It is common to find very thick electroplated jewelry , called solid electroplating. They are up to 2.5 microns thick.
