I have used tea (different brands, they really are different in effect..., potassium permanganate, different kinds of henna and even boot polish for staining. Generally speaking I found tea a bit on the drastic side. (At least the way I used it, which is boiling the carving in it for a minute or two.) Henna works quite well, at least some of the paler kinds.
Recently I came across a suggestion on a completely different forum (bagpipe one, to be precise) about staining ivory, which is by using iodine. Someone there managed to match a brand new ivory mount to a bunch of 100 year old mounts, which have of course gone quite yellow. According to the photo, it was a real success.
Anyone tried that?
Hey Juri,
Late reply, new here.
I plonk my cut offs in different stains. Just for fun and out of curiosity, not systematically yet, so no real specifics about duration etc yet.
Two things imho work best so far for staining: red bush "tea" (infusion really) and Iodine. Second started out accidentally, after washing hands with iodine soap, and spilling on a cut off. Seeing the colour, I tried iodine (not soap) on another piece.
First try: immersion in pure iodine
It stains quickly, and quite deep, to a rich colour brown/yellow. After some time it is through and through, as was clear after cutting the piece.
Dense bone gets a quite uniform stain. The spongier bone, and pieces that had the crosshatch stuff (what's the name for that anyway?) attached, stain irregularly, more like the pattern in deer crown. Guess that will be true for any type of staining.
Second try: brush on iodine
Again quick, just nor deep. Stains where brushed on, spreads while still wet. It does not seem to spread much over time once dry, but not sure yet. Way slower than grease anyway.
With the tea, the redbush gives a nice warm stain, orangy. It's not a cold colour like some black teas.
I just immerse it in normal strenght tea. The longer it is immersed, the deeper the staining and the warmer the colour. After cutting it shows more of a surface or shallow colouring than the iodine.
Someone told me it is good for brush on as well, haven't tried. He lets the water evaporate from the infusion and stores the powder till needed for staining, adds a drop of water and paints it on for shadow patches/undercuts.
Anyway, hope this helps, haven't got more specifics.
Cheers, Hans
