Finishing Your Metal: Sealing Brass and Copper to Prevent Tarnish
One last thing in terms of finishing is if you're working with brass, copper, or bronze, you might want to think about sealing it to prevent tarnish. So, oxidation is just a fancy word for tarnish that happens when your metal is exposed to oxygen, which means all the time in the air. And so, any metal that contains copper is going to oxidize or tarnish over time, and there are two solutions to that. One is just to say that's what happens and it gets a nice agey patina, or you can clean it off later, or you can seal it. So, I am a fan of two different solutions when it comes to sealing your metal. One is something called Renaissance wax, and Renaissance wax is literally just a clear wax. Clear, white, that kind of thing. And I always keep just a little rag in here. So you want something kind of soft. And then, the way that this wax is really designed is kind of like, let me move that out of the way, kind of like, wax on, wax off, which none of my students ever laughed at that joke. Whic...
h makes me really sad. So, you're going to put a little bit on, and then you're going to take a cleaner side of your rag and actually buff it off. What's nice about Renaissance wax is that it's not actually a permanent coating, so if for some reason you do have any oxidation on your metal, it's really easy to clean the Ren wax back off, and reapply it latter, so if for some reason you need to get in there. The downside of Renaissance wax is that it doesn't always protect perfectly and because you are buffing something on, if you've got any kind of patina or surface oxidation, it doesn't preserve it perfectly, you may end up rubbing some of that out. So let's say you did a really fancy patina, and you loved it, and then you put the Ren wax on, and you're like, "Well I just took half of it off accidentally." So that's the kind of downside of the Ren wax. Which is why another option that I really like is what I always refer to, because that's what someone else referred to as the bulldog spray, because there is a picture of a bulldog on there, which is actually just a sculpture, it's from a company called Sculpt Nouveau, and it's called Clear Guard. It comes in two finishes. It comes in matte and satin. The matte is pretty matte. The satin has got a little sheen to it. It will not magically make your piece shiny, so you still need to polish. What I like about it is that there's a low VOC version. So, it's like a dollar more, but it's totally worth it. So this is something if you've got a lot of stuff and you want to coat it, it's a nice kind of clear coat that you can just spray on and seal. So I generally recommend if you're going to work with brass, bronze, or copper, when get the finish the way you like it, hit it with one of these things to preserve it. And I would recommend doing that before you add your wires or jump rings, because it's going to be hard to buff this on if we've got our jump ring connection here. Trying to get that on is a little bit tricky. It's a little bit easier to hit with the spray guard, but it still, I would probably spray it once, assemble it, and then spray it again. Any questions about sealing the metal? And again, it's not required, but it's a nice little step.
For best practices to your purchasers, how do you recommend they care for their...
Yeah, so I always, first of all if you're selling things, I like to make a whole little care card for your customer. The biggest mistake people make with their jewelry, and I always like to tell my customers this is do not store your jewelry in the bathroom, because the humidity in your bathroom is horrible for every piece of jewelry. When people show me their jewelry, and they're like, "Why's it all tarnished?" and I'm like, "Do you keep it in your bathroom?" "Well yeah." "Don't do that." So I generally always tell my customers, don't keep it in your bathroom, so what I would recommend for people is telling them just to keep their pieces in something where they're not going to get scratched or things. So the biggest issue with designs like this is it's a big surface area that wants to rub against things and get scratched, so if you've sealed it properly, they shouldn't have to worry too much about oxidation. So what I would say is recommend to your customers that they actually store their earrings each one in its own little baggie. So instead of putting two together, in one baggie, where they scratch each other, I recommend telling them to store them separately, or store them hanging if they're not traveling with them, tell them to store them hanging. 'Cause that's going to be your biggest issue is things actually things scratching against each other probably more so than surface oxidation.
And along with this past content, The Landlocked Sailor would like to know, do pieces get bent up in the tumbler at all?
So, if you have something that's really fine, it could, But for the most part, I tumbled these guys that have the little ears on them, and nothing got bent in there, so unless you have something that's really, really tiny, it should be OK there, but if you think about it, you can throw in chain and that's not gonna get it, so they tend to not get bent, the mostly get work hardened.
