Topic tags/keywords: spalted maple

Last week, I had a piece of spalted maple that I took to work to show a coworker.. It was a very nice slab that looks like a spalted burl, as the grain looks like cinnamon on toast.

Unfortunately, I left it in my truck overnight and we had a freak rain shower out of nowhere and the top of the slab was soaked. I brought it in to the house to dry and checked on it a couple days later. I had weighed down the center to try to get it back to its shape, but when I checked on it, it was now cupped the other way, like a bowl. I also noticed that there was some fuzziness on the top. When I flipped it over, I found that the entire bottom side was covered with a mold or fungus of some sort.

My questions are
  1. is it still safe to use?
  2. is it safe to keep in the house to continue to dry out
  3. is there interest in the fuzz (I see some people on here from time to time trying to cultivate it)

I couldn’t believe how fast ‘the fuzz’ grew.. It was about 36 hours between it being soaked and it being a culture site. Also, this wood was KDed at one point.. would/shouldn’t that have killed off the culture?

My guess is that it was not properly kiln dried(not high enough temp).
Fungus is dead in kiln dried wood and dormant in air dried wood.

Fungal, mold, and mildew spores are all over the place. It does not matter that it was kiln dried because you un-kiln dried by leaving it in the rain. The spores were in the environment. The conditions were perfect for fungal/mold growth, and that is what happened.

Any wood that is kiln dried that is left out in the outside environment will re-equilibrate with the ambient environmental conditions, meaning that the wood will gain moisture, the amount based on the humidity. The board cupped because after it got wet, it dried more on the exposed side than on the underside, creating tension that caused the cupping. If you turn the cupped side down flat on a surface, it might flatten back out. Then, be sure and store it so that air can circulate freely around both side of the board until the board reaches equilibrium again.

Patron, I like your idea!

Thanks for the tips guys.. I already have it weighed down and its getting back to normal.. I may grab my respirator and scrape it down to get it looking like how it was
