Instead of using baking soda and cyanoacrylate to fil and repair bone/plastic nut slots and bridge bone inserts, has anyone tried bone dust or pearl dust (if obtainable)?

I've been using it for many years. I'm going to use it in a few minutes on one slot on a guitar that's come in for minor set-up.
But if more than one or two slots need to be filled and re-cut, I generally either shim or replace the nut.

Every time I cut a new bone nut or saddle, I save some of the dust if it's clean.
Be aware that CA and dust or baking soda will not stick well to some plastics.

Are you refering to bone or pearl?

The main difference is that baking soda acts as a catalyst for CA so it cures faster.
Personally, I don't use dust and CA, but instead vile a V-notch, superglue in a well-fit piece of bone, and re-cut the slot.

Use Blufixx. UV hardens quick. Then reslot.

I filled a white bone nut using bone dust from the same nut blank.

The CA darkened the bone dust to the point where the filled in part didn’t match.

I think of filling slots with anything as a temporary solution and after struggling with the mess of mixing anything with the glue I just apply a drop to the slot all by itself.
This lasts a good amount of time even when played every day.
My favorite fix is shimming under the worn nut with a piece of brass feeler gauge blade.
Usually an .008 or a .010 and then retouch the slots to spec.
