Market Harmony joined the forum a few weeks ago. He makes silver, gold, and copper products, some from scrap jewelry. I don't have any problem selling them on my website  |

Yes, I do that. I plan to move away from jewelry and non-pure scrap for the future. I'd like to only work with .999 gold silver and copper.
Overcoming the trust factor with buyers takes time and consistency. I decided to approach the issue with a professionally made makers mark stamp and a "999 fine silver" stamp. I also gaurantee purity. Some folks only want name brand makers, and I understand that, but silver is silver, no matter what the stamp looks like. Assay guns cost more than 15K USD. I plan to acquire one in the future years, and will then certify all my products as an assayer as well. It just takes time and money to get things rolling along.
I've already got well into 5 figures invested in the business, so be prepared to commit yourself to the long run if you decide to do it too. Basic equipment includes a crucible melting furnace, molds, and processing equipment.
I'll help you along at a consulting cost if you're interested. |

| Its not for me right now, just looking at it as a possibility for the future, ill bear that in mind if i do want to start doing it, how do you get your scrap then? i assumed you could melt less pure silver down, and refine out the other metals so it was .999, is this not possible, i like the look of those buffalo rounds on the copper cave, nice and generic, and a shape that buyers recognise and trust |

| It is possible to refine - but specialized work - and not really an operation for the garage. There are reletively few refiners out there. |

I took on a project to cast some custom bars for a forum. That was in November. I figured I would do sand casting and ship the bars about the second week of December. First I spent $60 on fire clay and stuff for a furnace. Then I spent $150 on a propane torch. The biggest problem was my instructions were from a guy doing a different sort of work. The furnace was for 10 lbs of aluminum, not 10 oz of silver. The torch was supposed to work without a blower, and it took a while to figure out it needed a blower. "A while" means I wasted two tanks of propane! I found better instructions for designing the furnace and by that time I was up to the third version and had to buy more materials to build another one. The guys who designed the forum logo went to professional engravers, first one then another, and they didn't quite understand that the engraving had to be angled, not straight sided. For any other purpose, engraving has straight sides, but straight sides won't release from a mold. It took a while to figure out why the system didn't work. By now we were into January. Another thing to be learned was exactly what treatment a crucible will tolerate and what will make it break. (If water touches it you have to bake it to dryness before using it again.) Cheap crucibles cost $15 each, good graphite ones cost $35 each. I gave up on the sand molds and spent $50 on graphite molds. Then I learned that "10 ounces" means gold capacity, not silver. So another $65 for a 20 ounce mold to make 10 ounce silver ingots. I finally got the ingots poured the first week of February and paid $180 for a custom steel stamp with the forum logo. But graphite molds usually have some weirdness that makes bubbles in the casting. Nobody knows why, but I figured out how to bake the crap out so they would make a smooth surface that would take the stamp. Then I remelted and repoured all the ingots.
Three and a half months and $800 on this first project. |

The magic word you're looking for is "draft." 
It's a standard process for any injection mold. Go to a mold maker and they'll know exactly what you mean. Go to an engraver that is used to etching designs on flat surfaces and it's probably not something they have dealt with before. |
