Anyone know what this is?
Really dense hardwood came in a random cut off bag, I have a few more that turn extremely nice but can’t seem to find anything pertaining to the highlighter like dust it throws off.
I have some Ipe that looks quite similar. The stuff that I have came from a decking sample. WoodDatabase also refers to "powdery yellow deposits": https://www.wood-database.com/ipe/ . There are many species under the name Ipe, so getting good direct comparisons is difficult, lots of variety.
