when filling a knot with epoxy, is there any difference if using stain vs dye to color the epoxy? have a dark knot in a walnut board. Wondering if the stain would be more cloudy than a dye.

thanks jocks.

I haven’t tried it yet but a friend uses the oil paint colors of burnt umber and sienna with epoxy and it looks good to me.

I usually use a five minute epoxy, brand doesn’t seem to matter, and add ink from a black pen, bics are cheap and quick to disassemble and I’ve never had a problem with the epoxy not setting rock hard. Even with the slightest amount of ink the result completely black. I’ve never tried just slightly tinting the epoxy if that’s what you’re going for.

Ooooh I like the Bic sourcing.

I use a much more laborious laboratory thingy: I have a stand with a candle and a rack above and I let the candle burn under a tomato sauce can until there’s a smear of lampblack (carbon). Snuff the candle, invert the can and mix the epoxy right there.

I have used HF 5 min epoxy but the bubbles tend to stay entrapped, sometimes resulting in one or two more applications. If I can do the job at the end of the day I use higher quality stuff, T-80, and the bubble problems are minimal next day.

This is one of the many gems I learned many years ago from Robert Miller, one of my two wonderful mentors. I wish I could find him to thank him.

I have used Transtint powder dye some it actually worked one time but that’s the only time I tried, I also used some marking fluid black and it worked really good cause I wanted that look of pure black epoxy in some deep voids and long cracks if that helps, but really I don’t do that much woodworkin anymore, have a good day make some dust

I have had a need to color a number of batches of epoxy black. I bought a small bottle of ink pad ink. Worked great, just don’t get it on your fingers.

I have mixed chalk line chalk (from Lowe’s) with epoxy to get a contrasting color to fill voids and cracks in Mesquite.

Read a tip about using food coloring in epoxy. Haven’t tried it yet myself.

Read about using Testor model paint as a colorant for epoxy so tried it. Worked great! It only takes a drop or two of paint, comes in just about any color and is very cheap.

+1 with JayT——-I color the epoxy for gluing more transparent pen blanks. I reverse paint the pen blank and add the color into the epoxy…it works great….but like JayT says don’t use any more than a couple drops.
Testors gives you a lot of colors to pick from and they are 1.50 per bottle.

I have a friend that makes acrylic pen blanks and he uses women’s powdered make up. I’ve never tried it, but it seems like it would work with just about any epoxy.

You can use powdered tempra paint to color epoxy and it works on waterborne and solvent based epoxies. The plus side is you can make some great special effects with bright colors.
