Growing a mass collection of great wood, I have some 600-800# of Cherry Burl, some 50+ year dried Walnut, Some 30 year dried mahogany, and now found some what I understand, spalted maple and a spalted poplar tree of sorts on my family land, getting wood for a bonfire at our company christmas party. I halted several chunks, and glued the endgrain. Didnt measure the diameter, but will. Maybe 14-16" in diameter for a few. And then of course, I am glad I invest in Triple Bond III by the gallon. Doing one end at a time to get the most glue to stay on endgrain as possible.

Ok, I'll bite. What's the purpose of the glue? Is it to seal up the ends so the wood doesn't crack until you go to use it?

Yea its to seal the endgrain to reduce splitting. This or anchorseal works. Or both in conjunction.

From my experience those logs don`t look like spalted maple, they actually look like ambrosia maple. The color reaching all the way from the center outward mixed with live, clear white wood is why I say this. spalting is the first stage of rot and while it may be capped by white sap wood it usually doesn`t mix with the living white wood. I haven`t had much luck keeping full round wood from splitting at least once from the surface to the heart even if end coated so I usually split it in half lengthwise and coat the split face
  Keep the wood in a cool dry place so rot doesn`t set in and  protect it from the bug infestation and you should be good. Nice find, I look forward to seeing what you make with it.

Thank you for a lead on an ID. Heres a few pics showing a scrap piece. Found a mill that can cut my wood into slabs.

Edit: Upon further searching now for ambrosia maple, i think that is what i have and not spalted and not any less beautiful.
