One key element that makes Alumilite work is that you MUST completely mix both A and B or your pour will fail, you won't have the chemical "connection".
What I do is take a small amount of A (just enough to mix in the colors) and put it in a cup large enough to hold your final amount of that color. I mix my colors in as many cups as needed.
Then I pour the A and B sides together in a larger separate container and mix mix mix until it's not cloudy.
Then I pour that mixture into the smaller color cups in the amount I want for that color, then mix that again.
Then without hesitation pour into your mold(s), mixing the colors as you pour. I take a skewer and swirl after that, but that's my "artistic" choice.
Then get it into the pressure pot at about 60 lbs immediately to squish those air bubbles you created while stirring and mixing.
I hope this helps, let me know if you have more questions.
Keep turning -
