I found the wood to be quite yellow-greenish in color, especially the fine dust from sanding.
Ultimately, the wood turned out quite nice and achieved a very beautiful natural luster well before I applied any finish at all just through very fine grit sanding down to 800. When I did apply the finish it took extremely well and served to further highlight the greenish color of the heartwood. I have never yet seen a wood with such a pronounced greenish cast and I was quite pleased with the effect.
I could easily see myself working with Mulberry in the future if I can locate reasonable sized pieces for a decent price. If any of my readers locate some, please do let me know.
As always, I wish all my readers a great experience in whatever their wood working interests happen to be and to those who like working with lathes especially, do a good turn today!
