I've been experimenting with the use of natural wood and resin to turn bowls and bottle opener handles. I have a problem with bubbles and "frothing" within the casting. The frothing occurs around the wood surfaces and also at the top of the pour. I end up losing the top inch or so...and never get a clean transition between wood and resin. They both occur with or without the use of a pressure pot. I have been using Aluminite Clear Slow. Should I be using a different type...deep pour, etc..? Any help/guidance would be appreciated!

We have a few people who work with wood here, can we have them chime in with some advice?

I recently switched from regular epoxy to Aluminite Clear Slow and have had no problems at all. I usually use a pressure spot but recently turned a large plate and while it did froth a little on top this came off anyway during the turning and was likely because I did not take the time to heat and dry the wood properly. Otherwise the project so far looks great. My projects with Aluminite have been excellent with wood or not. They come out very clear and bubble free but you do have to pay attention to the tips about pouring, mixing and drying the wood properly. Other epoxy products I have used do not give you the stunning effect you get when you add collars.

I, too have had serious problems with alumilite clear slow, both with casting and also with pouring on a wood product. I have never had a totally clear pour. I know all the lectures I will hear about too much part A but I have (2) gram scales that match and are very accurate …….. no question. So on my latest project I anticipated some white on the surface but I didnt expect the whole 1/4” pour to be solid white.
Here’s the details:
Humidity in the house 50%….(I don’t live in Arizona)
Temperature 70 degrees
Exactly 20 grams each of part A and part B (20 tare 20)
Mix for 2 minutes
Pressure tank at 70 PSI
Let sit overnight
Results…..solid white disaster
My gripe is that I think Alumilite needs to be very specific to the exact process as to the how and whys of how to get a perfect pour from their product. I know it is a beautiful resin in the right hands but to the non pros we need to be able to get answers from the chemists and engineers that have developed this resin.

Call Alumilite's tech department at (269) 488-4000 and they should be able to nail down what happened. All the tips should be on the data sheets but they might need to update them a little so you calling them for help might be what is needed for them to look back over the data sheets and be sure it's all there.

Try sealing the wood with a clear coat first. Polyurethane or epoxy work well but let it fully cure before casting.
