Hi guys, this is Rob and Perry with gold plating services and we're making another video for you today.
This one is how to do rhodium plating with the jewel master which is the option 3 kit comes with everything you need to do gold plating and also rhodium plating which the extra thing that it includes is this platinised titanium anode and the rhodium plating solution. So we have these gold-plated items here and it's kind of an industry standard with rhodium to either have them gold plated or nickel plated before doing the rhodium plating.
The rhodium solution is pretty acidic so if you put an item in there that's not gold or nickel plated it will corrode it really quickly if there's no current. So we're just going to get right into it. The first thing we got here is electro-cleaner these were freshly gold-plated items and so they don't have any fingerprints they're already really clean so we're not going to need to spend much time here. We did have it set it at 8 volts so you know drop down to about 7, 7 is usually good for electro-cleaning.
Now we're going to go into the surface activator now you may notice it's yellow because after you use it a time or two it changes from that pink colour to yellow. That's just normal and okay, not a problem. Did that only for a couple seconds as well, because it's gold. Gold does not require any activation actually, but you could you do it just for good measure. Double rinse, now we're ready to go into the rhodium.
What voltage are we going to use for the rhodium today? We're going to start out I'm going to start out with an initial voltage of probably five and a half or there abouts. You'll drop it in then we'll turn it until we go up to about four volts. The label says three to four but we're going to do it at four, just simply because, the parts are hanging on the rack and so we want to have a little bit higher voltage to make sure that the parts are getting the current they need.
So if they're clipped, they have a little bit better connection and this is just such a fine point of contact that we want to make sure there's enough voltage basically and look at how much amperage is pulling; seven and a half amps on these small pieces. So it's a power-hungry solution. Now the label also indicates, 30 to 60 seconds but we would recommend plating more like in the range of one to two minutes and so I think we're going to plate these for probably a couple of minutes.
Well, look how much gassing there is now in solution you can’t even see through it. Okay so we're just going to leave this going here. The rhodium is a room-temperature rhodium which our rhodium is, most are not and that's actually pretty convenient because it's just ready to go you, don't have to wait for it to heat up, you don't have to do anything to it. You just set up and get going it's really quite easy to use.
A lot of people don't know what rhodium is but when you go through the to the mall and looking the jewellery stores that the engagement rings and they call it white gold, what you're really looking at is a rhodium plate in almost every case. It’s very brilliant, it's about as white as silver, it’s about as hard as chrome and so it's a it's perfect for jewellery because it will never corrode. Rhodium is one of the most corrosive resistant materials that you can electroplate with, which can be a problem if you don't get it right. There is no chemically stripping it off and it's hard and so it's very difficult to polish off, so we try to encourage people that you're going to use a rhodium plate, make sure you practice you know what you're doing and you did get the parts thoroughly clean so that you don't end up with a problem.
We're going to go ahead and pull them out it's been a good couple of minutes. Let's check them out, let me give them a quick rinse here. Make sure they got covered everywhere. It's about as almost as white as silver and all right if you think they're good let's pull them down Hanson and see. Let's take them off, this little jewellery pendant.
So how long could you plate them like theoretically even before they start to look ugly? Well I planted stuff, for about, using this very solution for three or four minutes and it really didn't affect the brightness with if you play too long then you the brightness goes away and it kind of turns into instead of it being a brilliant white, sort of a battleship gray. If you in fact I've done technical plating for rhodium while we played in two microns plated it for more than an hour and it turns out great. Really, okay.
So for practical purposes you'd probably only need just a couple. Me, I'd say two minutes is fine it's going to give you a really good. I really did brighten that up, that little ball was more even. How about these black parts, they were pretty nice and bright. You know everything looks really good yeah.
There it is next to it, the gold stuff. This rhodium solution is really easy and it's forgiving but you just want to make sure that the part is either if it's freshly gold plated then you're not going to have to worry about it being clean. All right well there it is folks looks similar to silver but you don't get the corrosion and it's really quite simple to use with the jewel master. So if you don't have a jewel master, the option three would be the one to get because it comes with everything you need to do the gold plating and everything you need to do the rhodium plating.
The option 2 comes with just the gold package. If you already have a jewel master then all you need to get is that platinised titanium anode there and the rhodium plating solution and you'll be ready to go.
