Topic tags/keywords: question oak water oak spalted spalting burl bowl platter carving finishing

Hiya folks, I’ve got a Water Oak burl cap that I cut several months back that I have started working on. It was an ant resort in a former life. I am wondering if I need to do anything to it to stop the spalting process. It is filled with tons of worm/ant holes and is super spalted. I am thinking it will be a shallow fruit bowl or platter. Will the spalting continue or will it just stop when I carve it out, sand it and put butcher block oil on it? What kind of prepping do I need to do before I put appers and banenes in it? As always, thanks for help.

I would think that aplication of some sort of sealer should do the trick. I think you would need to cut off the supply of oxygen. Not sure butcher block oil will do that. Shellac is food safe and should do the trick.

The spalting is a process caused by the presence of live fungus organizims (sp?) in the wood. They require moisture to survive and will die when the wood reaches a reasonably dryness level.

Good luck with your project. I’m looking forward to seeing it.

Just get it dry and it will stop. It may continue for a while even if it is under cover until it gets dry enough all through.

Putting sealer on it would actually make it continue spalting, in my opinion if not properly dried. But once dry, you can finish as you please.

Just remember spalting is rotting wood so some parts may be or will get soft.

If you can rough carve it now, that might speed up the drying process.

Put it in the oven for an hour at 200, that’ll stop it
