What is lost wax?<\/h3>\r\n\r\n\r\nLa lost wax<\/strong> is a casting process that involves creating a wax pattern, which is then lined with a refractory material to form a mould. Once the mould has hardened, the wax is melted and evacuated, leaving an empty space into which the molten metal is poured. This process captures every detail of the original model, making this technique particularly popular for the creation of made-to-measure jewellery<\/strong>.\r\n\r\n\r\n

Stages of the lost wax technique<\/h3>\r\n\r\n
    \r\n \t
  1. Creating the wax model<\/strong> : The process begins with the sculpting of a wax model, often from a design supplied<\/strong> by the customer. This model can be made by hand or using modern technologies such as 3D printing.<\/li>\r\n\r\n \t
  2. Assembling the model<\/strong> The wax model is then attached to a system of runners, also made of wax, which will allow the molten metal to fill the mould.<\/li>\r\n\r\n \t
  3. Embedding the model<\/strong> The wax model is covered with several layers of refractory material, such as ceramic, to create a solid mould. Each layer is applied and left to dry before the next is added.<\/li>\r\n\r\n \t
  4. Wax removal<\/strong> Once the mould has hardened, it is heated to melt and evacuate the wax, leaving an empty space in the shape of the original model.<\/li>\r\n\r\n \t
  5. Metal casting<\/strong> The mould is then heated to a high temperature to prepare it to receive the molten metal. The metal is poured into the mould, filling the space left by the wax.<\/li>\r\n\r\n \t
  6. Cooling and demoulding<\/strong> After casting, the mould is left to cool. Once cooled, the refractory mould is broken to reveal the metal object.<\/li>\r\n\r\n \t
  7. Finish<\/strong> The metal object is then cleaned, polished and, if necessary, adjusted to fit perfectly the design supplied<\/strong>.<\/li>\r\n<\/ol>\r\n\r\n

    Advantages of lost wax<\/h3>\r\n\r\n
      \r\n \t
    • Precision<\/strong> The technique of lost wax<\/strong> enables extremely fine details to be reproduced, which is essential for the creation of made-to-measure jewellery<\/strong>.<\/li>\r\n\r\n \t
    • Flexibility<\/strong> It allows you to work with a wide variety of metals, including gold, silver, bronze and brass.<\/li>\r\n\r\n \t
    • Customisation<\/strong> : Thanks to this method, it is possible to create unique pieces based on designs supplied<\/strong> by customers, offering total customisation.<\/li>\r\n<\/ul>\r\n\r\n

      Frequently asked questions about lost wax<\/h3>\r\n\r\n\r\nWhat is the lost wax technique?<\/strong>\r\nLa lost wax<\/strong> is a casting method used to create metal objects using a wax pattern which is then melted and evacuated to leave an empty mould.\r\n\r\n\r\n\r\nWhy use lost wax for made-to-measure jewellery?<\/strong>\r\nLa lost wax<\/strong> allows you to capture the finest details and create unique pieces based on the latest designs supplied<\/strong> by customers, which is ideal for made-to-measure jewellery<\/strong>.\r\n\r\n\r\n\r\nWhat metals can be used with lost wax?<\/strong>\r\nThe technique of lost wax<\/strong> can be used with a wide variety of metals, including gold, silver, bronze and brass.\r\n\r\n\r\n\r\nHow long does the lost wax process take?<\/strong>\r\nThe time required to complete an object using the lost wax<\/strong> depends on the complexity of the design and the number of parts to be produced, but it can take from a few days to several weeks.\r\n\r\n\r\n\r\nIs lost wax a modern technique?<\/strong>\r\nAlthough the lost wax<\/strong> is an age-old technique, it is still widely used today, often in combination with modern technologies such as 3D printing to create made-to-measure jewellery<\/strong>.\r\n\r\n\r\n\r\nIn conclusion lost wax<\/strong> is a versatile and precise casting technique, ideal for creating made-to-measure jewellery<\/strong> from designs supplied<\/strong>. It allows us to create unique, detailed pieces that perfectly meet the expectations of customers looking for personalisation and originality.","protected":false},"template":"","class_list":["post-417","glossaire","type-glossaire","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/smvthailand.com\/en\/wp-json\/wp\/v2\/glossaire\/417","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/smvthailand.com\/en\/wp-json\/wp\/v2\/glossaire"}],"about":[{"href":"https:\/\/smvthailand.com\/en\/wp-json\/wp\/v2\/types\/glossaire"}],"wp:attachment":[{"href":"https:\/\/smvthailand.com\/en\/wp-json\/wp\/v2\/media?parent=417"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
