I have used black colorant supplied with the Acra-glas compound, or regular epoxy with graphite in it to color black, etc. But I need some that is white. Any idea as to what would be the best thing to shave/grind up to mix with epoxy to give it a white appearance?

I snagged this Uddha sword here http://www.bladeforums.com/forums/showthread.php?t=382285&highlight=uddha

from the 1/9 deals, and the handle is really much nicer than the pics show, but there are a couple of spots in the butt and the underside (you can just barely see in the pic at the bottom of the butt) where Bura had to fill because of the nature of the antler. He filled it nicely with some hard brown putty, but I wanted to blend it more. I plan on just grinding out the area and refilling, and if the color is right the blend should be almost invisible.

Thanks for any ideas.

I wonder if chalk would work.

Duh, gee, I have absolutely no idea why I didn't think of that. I think it would probably work very well. I'm not all here today...

Thanks Eric.

My first thought was a pool cue ball, then chalk. Nothing like trying the hard way first...
 
Chalk would work..or if you can find some old,dry bone and take a power sander to it and use the powder,I'd think that would do too.
 
Baby powder?

My only concern with these is they may not polish up very smooth, if that is what your going for. Probably smooth enough, though.

Eric.
 
I would probably try a chunk of beef bone (ground dust)...stronger than chalk anyway.
 
fine chopped fiberglass fabric and/or glass fillers? auto-body shops and such should have it. it's white to begin with. the problem is that it might be too shiny and you'll have to rough it up to make it more matte... it might still be too translucent.

maybe you could get some old beef bone and grind some of that up. it and/or the epoxy might age well with the natural material.

perhaps also some stone dust? marble... or other blend that's the same color. avoid plaster/gypsum dust though - it's going to have issues with water.

home despot might have drop in mixers for paint as well; also a pottery shop might have appropriate ground pigments.

good luck :)

Norm, there IS epoxy that drys white, you know. Is that not the look you want?

It is, and there is? I have 90 second, 4 minute, and slow set 2 part epoxies, plus grey metal bonding stuff, and JB Weld and JB Quik, but haven't seen this. I'll look for it.

But I should also have thought of Nasty's idea (and Bladite also suggested it in a follow up) as the bone would be a great match for the antler. I'll look for the white and if I can't find that I'll try the bone / epoxy mix. That would probably look more natural anyway.

Thanks everyone!

I'm with Nasty on this one, powdered bone or antler will be going to a bit of extra trouble, but probably worth it in the long run.

How about white epoxy colorant from Texas Knifemaker Supply?
www.texasknife.com

Stock # EPOX901 $6.95. One bottle should color about 500 lbs. of epoxy.:D Probably more than you need. If you get it, you may want to experiment with how white it is before you put it on the knife. May require just a teeny bit of black so it won't be too white. Or just put a tiny bit of white in the epoxy so it's translucent.

Thanks Steve! I know about Jantz, but hadn't used these guys yet. I appreciate the reference.

I would use ground alabster/serpentine dust, but I have ready access to all sorts of rock.
 

why not test several of the ideas
& let us know what matches best.

If you use white in a gold-brown setting epoxy
then you should be close to 'aged' ivory/bone color

since you need white
you'll need a clear setting epoxy
Every white source mentioned will be a little different appearance
once 'wetted' in the epoxy.


this post suggests use paint store colorant made for epoxy paint.

A couple people in the same thread use Testor's model paint
Which i have also used in the past
Easy to get several colors to custom mix to match

here's another thread general epoxy coloring

Talcum, A fine grained mineral having a soft soapy feel and consisting of hydrated magnesium silicate; used in a variety of products including talcum powder.

Used also to thicken undercoat paint. May be worth a trial.
Talcum powder would beat neem in the smelly stakes:rolleyes:

My 2 cents worth :)

EDIT - Eric you beat me. Baby powder = talc based :confused:
 
The best white pigment is Titanium Dioxide. It has the highest light-scattering of any white pigment, which means that it imparts the most opacity to anything into which it is compounded.

I have about 50 lbs of it, how much do you want? EM me your addy and I'll send a pound or so.

Alternatively, my local True Value has white epoxy from Devcon on the shelf. I forget the set-up time, either 15 or 30 mins.

Geez, Noah, that is really nice of you. I think a pound would be more than I need for this job, but I really appreciate the generous offer. I can think of some other projects where this stuff would come in handy. How do you come to have so much of it? I'll talk to you by email some more, and work out the shipping with you if we go this route.

Many thanks,

Norm
 
Duh.

Duh. Duh. Duh.


er, Norm?

How about I send you a piece of antler to grind, file, hit wid a brick to get granular stuffies for your repair?


sheez. I am SO slow.


I need an addy. Email me.
