As a jewelry enthusiast, there comes a point where you will have to melt your metal to achieve your desired design. The process of melting your metals can be a thrilling experience, but it can be quite tricky if you don't have the right tools. One important tool needed is a small graphite crucible.
A graphite crucible is a container used to hold metal while it is being melted. It is preferred because it can withstand high temperatures and is resistant to thermal shock, making it ideal for melting different types of metals like gold, silver, copper, and more. Using a graphite crucible assures that your metal will melt uniformly, and you will achieve precise results.
If you're planning on melting 18ct gold or any other metal, it is essential to understand that using borax is not always recommended. Most manufacturing companies advise against coating the crucible with borax and adding it to the melting metal. Let's take a closer look at why.
Borax is a white crystallized compound used as a flux. This means that it helps the metal to flow smoothly and uniformly in the crucible while preventing it from oxidizing. Although it is a popular addition to metal melting, it can cause some issues if not used appropriately.
When borax comes in contact with moisture, it creates a solution that tends to be acidic. This solution can damage the graphite crucible and weaken its structural integrity over time. Moreover, the borax solution can corrode the walls of the crucible, leaving it susceptible to cracks and breakages, which can be quite dangerous.
Manufacturing companies like (need remove brand name) advise against using borax because their crucibles are designed to withstand high temperatures without it. Their crucibles are made from high-quality graphite that is already impervious to thermal shock and corrosive substances like borax.
It is advisable to follow the manufacturing company's recommendation and not use borax with their crucible. However, if you have a different brand of crucible, you can check to see if they have any specific guidelines or recommendations for melting metals.
In conclusion, a small graphite crucible is an essential tool for anyone looking to melt metals like gold, silver, and copper. However, using borax is not always recommended, and it can cause damage to the crucible if not used appropriately. It is important to follow the manufacturer's advice to avoid any detrimental effects on your crucible's structural integrity. With the right tools and knowledge, melting metals can be a smooth and efficient process.
