Hi Jerry,

The pour would need to be done in layers around 15mm thick to prevent the resin overheating.  In reality if the pebbles take up a large amount of volume you will probably be fine even at 20mm or so as the heat will soak away.  Pour subsequent pours when the previous pour is firm but tacky and the resin will bond perfectly to the previous layer with no or virtually no visible join.

I have got a thick piece of Oak (about 2.2" thick) that has dried out and I will be making a coffee table with it.
The piece has got a couple of large knot or branch holes that go through the thickness of the table and I would like to fill these holes with epoxy resin and small pebbles as well as cover the rest of the table with the resin to give a clear shiny look.  I have never worked with resin before.
Can you advise me how I would go about it.  Would I fill the holes in layers or would I do it in one go?  I'm assuming layers because of the pebbles in which case how deep should each layer be?  Do I do one layer, let it dry, lay the pebbles and do another layer and when that is dry finish off the rest of the table. 

Many thanks for any help
