Seemed amazingly intrecate to make one ring, but that rubber mould will bbe made to make multiple wax versions of the original ring. I assume that this is disposable and melts when moulten gold is poured into a sand mould. I have a couple of technical words that I think are related, like die as in die cast and former. It makes you wonder how they originally dreamt up this manufacturing process. You have to be impressed with the ingenuity. I'm always impressed with the early physicists who formulated the movement of the planets around the sun and the precisely timed astronomical events. Would like to see the finished article. Is Carlos a trained jeweller or a businessman with a watch and jewelry business?
Yes Andrew, the wax mold melts away when the molten metal is poured into the mold. We'll cover that part on another video. Carlos is an entrepreneur and the face and founder of CRM Jewelers. He talks a bit about his history in the CRM family video we released in April of May of this year.
@@andrewholt3849 Indeed Andrew. I've watched this video before. We've wanted to make a modern video on the gold refining process, but these places are typically very secretive and ridden with mystery. One day perhaps 🤷
There are quite a few that played after that. They have to use Chlorine gas to remove impurites as I remember it is highly reactive, but Gold is very stable and unreactive, why it doesn't oxidise and is better than 904L steel. I have another video abbout Gold from the BBC, which I put on my Instagram about the Bank of England Gold store as it's all related to economics and maintaining the value of currency. Apparently we in the UK sold off a lot of our Gold reserves and the Bank of England acts as a repository for other countries' Gold and refused to return it to a South American Oil producing country, probably Venezuela.
@@Crmjewelers 3:12 I’m starting a jewels shop and still amateur . Could you if there is a possibility make a video how to cut and why you cut in that way. This video seemed was little fast 🙈.. Like this ring you cut out , you cut around and cut out some part of the mold, when I watch other videos of other channels the dived the mold into two, but you dived into many parts . Sorry for the long question best regards and have it best! ❤️ sincerely
Hi Andrew Vulcanize rubber is the one you have to cook , in this case when you vulcanize the rubber layers together it becomes one solid piece of rubber and then you cut it to get the piece out and make sure when you inject the wax , it comes out good the piece you’re duplicating
@@gastonrives3392 Thanks, I was really referring to the Audemars Piguet Royal Oak Offshore 44mm straps as I originally followed CRM regarding watches and is where, about 2015/16 I first saw AP ROO 44mm and 42mm. Their straps are top quality vulcanised rubber. When I have looked into it it mentions Sulphur is incorporated into the rubber in some way to make it higher quality and harder wearing.
La savia liquida que se extrae del árbol de caucho se diluye con agua al 15% y se mezcla con ácido ácetico o fórmico para que se solidifique y luego se seca, ese es el caucho natural. Despues ese caucho natural blanco es mezclado con 3-10% de azufre y calentado de 100 a 150C para obtener el caucho negro, que tiene más resistencia. Este último proceso es la vulcanización.
