How to color epoxy?

[Dmay]

I have to do some Bubba work to a synthetic stock. Would like to color some epoxy black. What will mix into the epoxy without affecting it...... shoe polish?.....acrylic paint?......

I would stay away from any wax or oil based product. Maybe consult with a paint store to see what tints they have. A little goes a long way.

you can add a little powdered graphite to expoxy. works quite well.

Carbon black....aka soot
That is what goes into paint, plastics,stains,nail polish and yes epoxy, to make them black.

Graphite is mostly composed of carbon so it will also work as long as you have a VERY fine powder...but graphite tends to make a silvery black coloration....perhaps this is what you want however. Not having seen the stock in question

I've got some black epoxy die that I bought at the same place that sold the epoxy. They sell epoxy and fiberglass products and have all the associated fillers and dies etc.

Lee Valley sells black "rare earth" powder that mixes very nicely with epoxy. Mix it thoroughly first with the resin, then mix in the hardener. Do not spill any, as it's super fine and tough to clean up.

I've used the Bondo Easy Finish Epoxy Bumper Repair Adhesive found at Canadian Tire with pretty good success on a few projects. Despite the Q&A saying it is yellow when dry, it is indeed, black. A 30ml tube is $12.00

They used to sell powdered "earth pigments" at Lee Valley that were perfect for colouring epoxy. With a bit of practice, you could match any colour of wood.

Buy some real black pigment. Composites Canada sells the same stuff we used to buy by the gallon from the maker. 4oz is about $15. You can add about 1 gram to about 25 grams of epoxy with no ill affects. CC calls it pigment for polyester resin but don't let that scare you, it's in a glycol base and works fine for epoxy as long as you don't add a huge amount. We made a few thousand stocks with it. I don't think LV carries the powdered pigments anymore.

Tempera paint. It's the powdered stuff used in schools. Mind you, acrylic paint is epoxy. Think dollar store.

Yes that's it - earth pigments. It seems they're no longer carried by them though.

Still on the pipe eh?

Most places that sell polyester resin and fiberglass cloth or matte for repairing fiberglass boats or automotive repairs also sell little tubes of coloured pigment.

Thanks to all for the suggestions, I appreciate it.
One kind soul is even sending me some pigment.
