I am new to alumilite, but, I am a life long wood worker/carver. I poured a test mold last night with highly figured cherry which I've had for 30 years. I had stabilized the cherry with cactus juice for 5 hours in a vacuum chamber at -3, then baked it at 200F for 3 hours. I colored the alumilite with their ocean blue powder. I had the mold in the pressure pot within five minutes of mixing and hoped for beautiful clear features against the cherry. Unfortunately the result is the appearance of white milk everywhere the alumilite is touching the wood - everywhere else the alumilite is nicely blue tinted and clear. Why? the milk?
Is it because a few hours before I poured the mold I had used a Q-Tip to soak the cherry with cactus juice? I did this because the wood had lost its sheen in the oven.

I think the answer is in your last sentence... it sounds like you had some uncured Cactus Juice on the wood that was never catalyzed and that reacted with the Clear. There are only a few things that will make the clear turn milky/wispy white, off ratio, incomplete mixing (blending), or not fully cured because of moisture.
