  • Qual é a melhor ordem para usar?
    Para o caso de peças usadas, recomendamos começar pelo Accende Abrilhantador, para remover as sujeiras que podem atrapalhar na remoção da oxidação e contaminar a solução, fazendo com que ela perca o efeito mais rapidamente.
  • O Accende Desoxidante pode ser usado no latão?
    O Accende Desoxidante foi pensado para joias e semijoias de prata e ouro somente. No entanto, clientes nossos testaram o produto em latão e deu super certo! Recomendamos separar a solução para usar somente em um metal (não usar a mesma para prata e latão, por exemplo).
  • Pode usar em peças novas?
    Não recomendamos o uso do Accende em peças novas para proteção contra oxidação: estamos desenvolvendo um produto específico para essa finalidade!
  • Pode usar em quais recipientes?
    O Accende pode ser usado em quaisquer recipientes de plástico e vidro, inclusive pode usar os recipientes normalmente para outros fins depois de lavar. Só não recomendamos o uso de latas e outros recipientes metálicos.
  • Como descartar a solução?
    Tanto o Accende Abrilhantador quanto do Desoxidante tratam de soluções não nocivas e podem ser descartadas normalmente em ralos.
  • Existem contraindicações para uso em pedras?
    Diamantes, safiras, quartzos, ametista, zircônias são seguras Lápis lazuli, malaquita, rodocrosita, pérolas, em geral não são recomendadas para o uso, apesar de termos clientes que usam com sucesso nós não recomendamos. Esmeralda depende do tratamento de óleo, pode ser removido ou não no Accende Abrilhantador, por isso não recomendamos também, apesar de termos vários clientes que usam com sucesso.
  • How does the acid test for Gold work?
    The acid test for Gold is composed of a mixture of acids that reacts with the gold alloy, so if the jewelry or piece of metal has an alloy with a lower karat percentage than described on the test label, this mixture will react with the alloy. For example, if we have a piece of jewelry that we think is made of 18K gold, which corresponds to 75% gold, and then we apply the 18K Gold Acid Test and the mixture of acids reacts with the jewelry, this will mean that the jewelry was in fact less than 18K gold.
  • Does the acid test damage the analyzed object?
    The acid test damages the object since, in order to be carried out, the professional must scrape (wear down) a region of the piece to carry out the test. However, so that this scraping is not so apparent, it can be performed in specific places, such as the back of an earring.
  • Como funciona a validade dos testes de ouro?
    Os nossos testes de ouro valem por 2 meses a partir da data de fabricação (carimbada no rótulo). Eles têm essa validade porque levam uma mistura de ácido nítrico e ácido clorídrico na composição, esses ácidos reagem entre si e se degradam, por isso, quanto mais forte o teste menor a validade. Temperaturas mais altas e exposição solar aceleram a degradação por isso é importante guardar em local fechado.
  • Is the acid test dangerous? Is the acid test controlled by the authorities?
    The acid test for Gold is dangerous because it is composed of a chemical substance considered dangerous, which is nitric acid. Therefore, this test must be performed safely by a qualified professional, always following safety protocols, such as the use of nitrile gloves and safety glasses. Despite being a dangerous product, our Acid Test is not a controlled product. We added a denaturing component to its formulation and it went through a series of regulations, which allowed us to obtain an exemption from control by the Ministry of the Army, which can be consulted through the Official Letter No. 1064-SecEstTec /Sec_Plj_G/GabSubdir June 18, 2021.
  • Is the Acid Test for Gold effective?
    The acid test for Gold is able to differentiate pieces of jewelry made of non-noble metals from those actually made of gold, and can also distinguish, for example, 18K gold from 14K gold alloys. It is a cheap and simple method that has been used for a long time. The test cannot be considered a type of analysis, as it does not have the precision that X-ray fluorescence analysis and other techniques offer, but it can be considered a semi-quantitative test.
  • Is X-ray fluorescence analysis accurate?
    When we compare the X-ray fluorescence analysis with other types of analyzes on the market in the same price range, we can conclude that the X-ray technique is accurate and punctual. For example, in a homogeneous piece of metal this will mean that we can obtain data such as the composition of the metal alloy used or the solder that composes it. However, if we have a non-homogeneous piece of metal, we would not be able to obtain data on the composition of the entire piece, only on the analyzed part.
  • Does X-ray fluorescence analysis damage the analyzed object?
    X-ray fluorescence analysis does not damage the analyzed object, leaving no scratches or creating any kind of deformity, so this technique can even be used on old pieces such as those from museums and antique shops.
  • Is X-ray fluorescence analysis dangerous?
    The technique is not dangerous as the entire analysis takes place in a closed chamber with only the sample inside; it is, therefore, a safe technique, since the chamber has a closing lock and the equipment only starts working when said lock is closed. It is also worth mentioning that nowadays X-ray fluorescence equipment no longer works with radioactive elements, they now have a “lamp” that only emits radiation when its tube is connected to electricity.
  • Existem quantas técnicas para analisar? Só através de raio-x?
    Existem inúmeras técnicas de análise, depende do que se deseja analisar! Podemos enumerar: Raios-X (XRF) Teste de Toque Teste de toque eletrônico Teste de condutividade elétrica Balança d'água Copelação Análise por espectrômetro de Absorção Atômica LIBS (Laser-induced breakdown spectroscopy) A única técnica que não é destrutiva e dá os teores dos metais é a Análise de Raios-X
  • What is Rhodium?
    Rhodium is a chemical element (symbol Rh), with atomic number 45 and an atomic mass equal to 102,9 u, and is located in the 5th period and in Group 9B of the periodic table. Rhodium is a metal, classified as noble and precious, which has high hardness, high chemical resistance and is also one of the whitest metals on the periodic table, second only to Silver.
  • Why is Rhodium used for plating jewelry?
    Rhodium is a noble and precious metal with high chemical resistance and hardness, and is also one of the whitest metals on the periodic table, second only to Silver, so it offers a great shine when deposited on jewelry pieces. Unlike Silver, Rhodium has a high chemical resistance, so it does not easily undergo any type of oxidation process, and for this reason, the Rhodium electroplating bath is widely used for plating jewelry.
  • How to say "Rhodium" in portuguese?
    The correct name of the chemical element in Portuguese is "Ródio". However, as studies of precious metals are still rare to find in Portuguese, we commonly write the name of the element in English (Rhodium). A simple and safe way to know if the element in question is Rhodium is through the periodic table symbol, which is universal, as it comes from its Latin/Greek name (Rhodon), meaning that both Ródio (Portuguese) and Rhodium (English) use the same symbol (Rh) in the periodic table. The terms "Rhodio/Rhodia", which are also used in Portuguese, are adaptations of the element's English name.
  • Is there a White Gold Plating Bath?
    In fact, white gold plating baths do not exist. Pure gold has a yellowish color and only when we have the addition of another metal, forming a metal alloy, can we have a change in color. Thus, with the addition of metals such as Palladium and Nickel to Gold, we can obtain a certain white color, but it will still have a grayish appearance. Therefore, it will be necessary to carry out a Rhodium plating on the piece, making it harder and also giving it a lasting shine. In short, the term “white gold plating bath”, which was widely used in the past, does not really exist, and what we have is actually an alloy of white gold, silver or even a semi-fine jewelry that has received a Rhodium plating.
