dyeing bone question

[peppin72]

Hi,

A couple of years ago, when I was in New Zealand, I did a bonecarving course.
After finishing the object I dyeed (or is it dyed )it. It gave it a nice antique look

Back home I fixed some cowbone and started carving .
By now I've finished a couple of pendants.

I want to dye them but I just can't seem to remember how or with what

I want to say : with tealeaves; but I'm not sure.

Does any of you know how to dye bone?


Thanks ,
Pepijn

Fabric dyes like Dylon work;
potassium permanganate can be used to darken bone & antler;
stains used in microscopy also work (well, they stain everything else!).

Thanks ESpy,

Using a wet tea bag works good to add age to bone and antler.

Somewhat nicer than working with KMnO4, too... Is there a reaction involved, or does the tea just sit there (and possibly dissolve out later)?

Thanks guys,

Did some googling and found out that it can also be done with cold (instant)coffee.

So I took 2 tablespoons of coffee and just enough water to solve the coffee,in a cup, and threw in some leftover pieces of cowbone,antler and ivory (don't worry;nothing illegal,just an old,sawn up billiardball).
Left it there for about 6 hours and .....tadaaa ... it has a nice antique look now.
Kinda brownish.
The smooth parts of the surface were a little less tanned then the rougher parts.

Also a cup of water with 2 teabags coloured some pieces.
Just a little less dark.(yellow)

Well,that was a nice experiment

Again,thanks for sharing.

Have some nice carving time down there!!

Enjoy the beautiful country and perhaps you could attend a bone/jade carving workshop.
