I am getting ready to pour a 12" diameter, 4" deep platter of resin. There will be some small pieces of wood suspended in the resin. The pour is too big to fit into my pressure pot or vacuum chamber so I am going to have to do it open air. I have used up several gallons of Alumilite clear slow in a number of bowl and vase turnings but was always able to finish in my pressure pot so I have never had bubbles to deal with. I am using a translucent dye so that the pieces of wood will be visible so I MUST not get bubbles. I was thinking of pouring it in multiple thin (1/2 inch) layers where I can torch the bubbles out between each layer. The trick is that I can't stop and sand between layers because of the wood pieces.
My thought was to allow each pour to start setting up but not fully harden. Then pour another and repeat over and over. Will this work? Will the layers bond? I will be turning this so bonding is important. I don't want to waste 2 gallons of resin and scrape the pieces of buckeye burl. Thoughts and advice?
Here are some of the turning I have made using Alumilite. The purple platter is the small version of what I am trying to accomplish.

Yes this will work. I constantly pour multiple layers of resin (RC-3 and Clear) one after another with no problem. That being said, be sure that the wood is completely dry (the slightest moisture will give you bubbles) or completely sealed. Mix slowly, pour slowly and in a very thin stream and you should remove the majority of bubbles. Resin will bond with resin no matter how long (or short) a time between pours.
