I'm trying to get a solid gold color using clear slow, so far with no luck. I tried Alumilite's gold powder but it turns out darker
than I'd like, I want a bright polished gold look.
Does anybody know of a good dye or pigment that might work?
I'm wondering if I can add an acrylic paint to clear slow, has anybody tried this? Will it mix?
Thanks.

You should be able to paint the resin if you already had the gold color you wanted. If you're using a mold, you can paint the mold itself (either with the gold or a clear primer) before pouring. Acrylic paint should work but I've only tried the paint on RC-3 and that was a spray and not a dye or pigment so it might not work the same.
I know RC-3 needs to "bond" with the paint (or primer) so it needs the heat of curing to do so which is why you have to either paint the mold itself (with either primer or the color) before pouring or immediately after it hits hard enough to demold. I'm not sure if the clear slow works the same way but I would think it does - I've just not tried it myself. If I can get to it today, I might try experimenting with some clear I have on hand with some acrylic paints I use on glass.

I don't use shaped molds, I cast blocks and then carve them to shape on my lathe.
I don't want the color *on* the resin, I want the color *in* the resin.
Do you know if acrylic paint can be added to clear slow and then poured? I've heard
of people doing so with epoxies (at a ratio of 1:10), but clear slow is urethane...

Okay I finally got around to testing acrylic paint with Amazing Clear and I've got some ...results.
Now I did silver and gold - the gold showed up a little better than the silver but silver is a lighter color so it's not that surprising. I mixed each color into side A before mixing A and B then turned around and stirred them again a few minutes after I poured. Neither one liked to stay mixed with the Clear and it was more noticeable with the gold as it's a darker color but after the second remixing, the color stayed better but there are still "swirls" in both. Now this is old, cheapy paint which may or may not have been a factor in how they came out. Also I didn't use a lot which also may have been a factor. Now I do have some good paint which is a multi-surface kind that is newer and probably would have given better results but these were what I had in a metallic so they were what I grabbed.
So verdict is: it IS do-able but it won't necessarily give you a "uniform" coloring. But you might get a different result than I did. You could try one of Alumilite's liquid dyes and see if that comes out better but again - you'd have to experiment to find out.

That's very interesting, thanks for taking the time. I'm encouraged and I`m going to pursue this further. I will update.
Thanks again!

You're welcome and please do experiment and let us know how it turns out.
I personally enjoy pushing these products to the the limits to see what they are capable of and the only way to do that is to experiment - one of my favorite ones was a small batch mixer for the Plat that combines a whisk for milk frothing and an electric screwdriver, that thing saves my hands from cramping and tiring out so much that I use it every time with any mold under 400g. It's just fast enough to not add a lot of bubbles, it's lightweight on my hands, and does exactly what I want.

Well my first attempt was a disaster. I used some Lumiere by Jacquard 550 True Gold; Ive read that Jacquard paints are great... I put maybe 1/2 tsp. into 4 oz. of clear slow. It mixed pretty well so I poured it into a pill bottle and popped it into a pressure pot at 50 psi for two hours. The result is attached. Yikes. Maybe I should try some of that old cheap stuff you mentioned, what brand did you try? ![]() Attachments:

Whoa, popcorn anyone? Kidding aside, I used an old bottle of Folk Art paint - so old I can't remember when I bought it and I haven't bought paints for at least a year. Could the pressure pot be part of why it did that? I don't use one so my test also didn't involve the ups and downs of pressure.

I don't think it has anything to do with the pressure pot, I always leave a little in the mixing cup and it foams worse than what I pressurize. Here's my second attempt, this time using Deco Art paint. Same story, about 1/2 tsp. into 4 oz of clear slow, poured into a pill bottle and pressurized to 50 psi for 2 hrs. Another disaster. I have ordered some Liquitex acrylic non-metallic plain old artist paint for my next attempt. If that doesn't work I guess I'm gonna have to disappoint a customer and abandon this project.

I can't believe I missed that part, d'oh! Amazing Clear Cast is epoxy. I'm using Clear Slow, which is urethane. This explains the different results. I'll have to go a different route or give up on this project. Can I pour ACC 4+ inches deep? It'd be about a 20 oz. pour. |

Ah, I missed it too! I forgot the two different kinds work differently. But yes you should be able to pour it that deep, there's a video of how to use it to make an imitation marble counter top that has to be at least 1-2 inches deep if not a little more. Here's a quote of what is recommended:
"Application thicknesses greater than 1/4" in a single pour may shrink, discolor,pull away from surfaces, and/or warp. Where thicker coatings are desired, it is recommended to pour multiple coats. Additional coats can be applied no sooner than 3-4 hours and no longer than 12 hours for optimum adhesion."
You make the eggs at that depth right? What I would do is mix up about half of that at a time and do it in at least two layers, maybe three or four. Though you might want to do more than one egg at a time to get the most out of the time you take to do each one. You might be able to shorten that 3-4 hours in between by adding a little heat to the mold (if you use one) beforehand, a little heat after pouring, and/or both. Let us know how it comes out.
