Has anyone cast two colors in Alumilite? If so, do you mind sharing your method? I don't seem to be able to get mine under pressure fast enough after they begin to gel to eliminate the small bubbles.

Was having that issue because I waited too long. Right when it gets hot I pour now and seems to do fine. Minimal if any color blending.

Here are some call blanks I just finished.

I mix the colors with part A before putting A and B together. I made a tricolor blank set in PVC back in March, it worked out because it was cooler in my shop giving me more set time. Turntex advises that it is OK to induce cooling during hot months. BTW my tricolors were, purple, pink, and the white Alumilite... so really it was just 2 colors and a third stir and pour.

Thanks guys for the input.
I spoke with Curtis this afternoon and he told me he doesn't wait, just pours the colors together.
Looks like I'll be experimenting tomorrow.

If you just go ahead and pour you can get color bleeding. If that's not an issue with the colors you're using then go for it. If you want the colors to get a bit more separated try waiting for the mixing cup to get warm in your hand. If you can feel the heat POUR. You should still be able to get things under pressure quick enough.

So far my max has been 7 colors: http://i1136.photobucket.com/albums/n496/Brooks803/DSC03446624x700_zps952cbd8e.jpg

Nice bunch of casts mate, well done...!

Interestingly, out of the "few" Resifills (my name for wood and PR resin casts) I made over the years, the mix on your blank far to the right, is very identical to one I done a couple of weeks ago with some Truffle wood, and done without thinking how it could come up, I just think of 2 colours and mix but, the "camouflage" look was something that I never did before, I was a little surprised when I sprayed the blanks with varnish for colour enhancement, all the colours together, turn out the camouflage look I'm talking about, and now listed on my eBay store (have a look)...!

One of the joys of casting the way I do, I target for NOT to make the same mix twice, that's what I like most about it, you get more "surprises" that way...!

Cheers

For my 3-color pours, I generally have a primary color and two accents (and I'll have more resin in the primary color than of the other two combined). I mix the pigments into one or both sides, and then combine the A and B of each color. I stir in turn until they all get warm. If one starts to kick before the others, rapid stirring of the cold ones will speed the reaction. When they heat up, I pour, swirl, and pressurize as quickly as I can.

I hope that helps,
Eric

That's also how we do our 3 colors, but I usually have to help Fred with those...:biggrin:
 
Monty,
I've only gone through about 2 1/2 gallons of alumilite, so I'm definately not an expert. I do get pretty good color seperation though. I mix A and B together first, then pour off the additional colors into cups. I will then tint all the colors. Usually by this time (or very shortly after) the resin has begun to set (get hot). I then pour the colors and swirl. This method keeps me from pouring before the resin is ready. I don't work at break neck speed, but I dont diddle dally either. Good luck my friend and I hope this helps!!!
