View Full Version : What should I do with this wet chunk of wood?

I just bought a chunk about the size of a normal red brick of spalted maple off ebay. It's freshly cut and wet to the touch. It's starting to grow a little mold. I know I need to dry it out somewhat quickly to get the mold stopped and to prevent the spalting fungus from softening the wood further. The wood is so spalted and figured I can't identify a face grain and end grain side to figure out which is the end grain to coat it with wax. Should I coat the whole thing in wax? Just let it air dry as-is? Try to microwave dry it?

What do you think?

Spalting doesn't necessarily weaken a wood... I have plenty of spalted wood that's hard as a rock. Coating the entire thing will certainly prevent loss of moisture and further mold, so it's a vlid plan. If you'd like to dry the piece, however, consider sticking it in a paper bag with some wet shavings and let it dry slowly. Other options are boiling for a few hours, soaking in a DNA bath, and using the microwave to dry it quickly but in a controlled manner.

If you can't identify the end grain to seal it, just let it air dry as-is. The longer it stays damp, the longer the fungal spores will continue to grow. Once the MC gets below 20%, the fungal growth will cease.
You might saw a thin slice off the end/side to better identify the grain. If you can find the end grain, seal it with some paraffin wax (or Anchorseal if you have some).

Ty, if you plan to use it for turning simply coat the entire piece in end sealer.
