Costs a lot of money to work these woods. Seems like a shame to just dump the sawdust in the trash. Would be interesting to come up with a use for it. Personally, I use a coffee grinder to make very fine powder and scoop 1/2 tsp into a cup of acetone to leach the color into the solvent in a mason jar. Use a coffee filter to filter out the swarf. Add this pigment to your favorite oil. Store in glass mason jars with metal lids.
This “essence” can now be used not to stain other woods but to rejuvenate the very wood that it came from. If you notice the wood aging because, for example, the sunlight tracks a path via nearby window that causes a streak or dry spot on your furniture, you can fix it.
The “stain” is a 100% color match for the wood because it came from the same wood. It’s foolproof.
A lot of people like to talk about how they never stain wood, but that’s in the context of applying a color that did not originate from the material you are applying it to. Plus, you get this color for the mere cost of acetone, mason jars, and coffee filters.
That is, only if you mill your own wood.
