A 3/4 x 6 inch blank would be around 3.5 ounces of resin, maybe at the most 4. Depends on if it's round or square too...a round one might only be 3 ounces or less. You are better off pouring into blocks as opposed to singles. It is easier to control your swirls in a larger mold. Picture number 2, I can't guess how to pour that one, not with alumilite anyhow. With PR, perhaps, because you could pour thin sheets of white and let them run close to setting, and then you pour a thin sheet of black on one sheet of white and then place other sheet of white over top..or it could be side by side with white on either side and then again you don't let it totally set, just come close but still be pliable and then you would push and pull on it so you get thick and thin spots and then cut and put in molds and re pour..that's my only guess on that one. The last one is real easy..you pour a block then smash the hell out of it, throw the chunks in a mold and pour again...again this works best with PR, because PR is brittle and easy to smash the heck out of it, and with Alumlite, you put that on the floor and hit it with a sledge hammer and it might laugh at you! At best, you break it into a couple pieces..you pretty much need a grinding machine of some sort to get it broken up like that with Alumilite.
Pour number 1 can be done with either product..probably a bit easier with alumilite, but either way, just need some practice with the timing is all. Both products can produce this effect if you pour it right before it flashes off. You need to find out which color will flash first. I already know with alumilite, the white paint is going to flash first. So the white would be stirred first and then the purple. So the white will start flashing off..getting pretty hot, time to pour fast, in goes the white first, about 1/3 full then get that purple which will be more liquidy and splash that in real quick and then get that white back over top before it becomes so flashed off it won't pour. See..with PR, the technique is pretty much going to be the same, but you will wait much longer for the flash to happen. If you pour too early, the colors may be different weights and they will be swirled in the beginning, but then the heavier color will settle to the bottom and you will have a kinda layered ugly blank. The same thing will happen with Alumilite, but you will never get a total settling of colors because the flash time is so fast. With alumilite, you will have to use pressure..no pot, no alumilite. Pr can be done right on the counter, you do risk trapping a few bubbles, but if you do, it should be minimal enough to spin and maybe fill a pin hole with ca if at all..the bubbles will generally float up..just depends on how much flash is happening during the pour..too much will trap more, not enough and you get settling of colors. It does take a lot of practice. For 36 blanks to be poured by yourself, I would definitely use PR, as you will pay 5-6 times more for alumilite, and then need a pot on top of it all. You can buy Alumilite at a more comparative price to PR..like maybe only 15-20% more cost, but to do so you need to buy large quantities.
