Topic tags/keywords: woodturning inlay stone

Hello all,

I have just started experimenting with crushed stone inlay on some of my turning projects.
I ordered 5 different types from Great South Gems and Minerals.
Aragonite Crystals
Calcite Blue
Calcite Red
Sodalite Specimen
Calcite Emerald Colored
I have crushed and inlaid using CA glue 3 different stones for practice/testing.
The results are disappointing, all 3 have a dull white powdery look to them.
As I was crushing them I did notice a lot of white/opaque dust resulting from the crushing, the original shine and color of the stones is really compromised.

I have seen many beautiful examples on the web, and I have read many tutorials on the procedure.
Clearly, I am doing something wrong. So I turn to my fellow turning geeks to help guide this geek in the right direction.

The picture shows 3 different stones.
Calcite Emerald
Sodalite (blue)
Calcite (Red)

Is this a normal result from calcite stones??

Thanks all
Kurty V

Have you put a finish back over the project yet. When I did turquoise it looked white and opaque but when I but the clear finish over it, it looked great. Even an oil finish over it should help. The turquoise was quite dull after I sanded it smooth but as soon as the finish went on it really brought out all the colors. I also used some black crushed garnet in a table top knot and same thing and that finish was 1/3 boiled linseed oil, 1/3 spirits, 1/3 gloss varnish and looked great when done. I think you should try a finish over it and hopefully fixes your problem.

Kurty—Just as finish will cause the wood grain to ‘pop’, so will it effect the inlay work.

If you don’t want to experiment with actual finishes, you can get an idea of what it will look like if you just dampen a rag or paper towel with mineral spirits and wipe it down. The mineral spirits will flash off, leaving a clean, dry surface ready for further sanding or finishing.

I gave the piece a quick wipe with denatured Alcohol, waited a few minutes, then gave it a quick 30 sec circular rub with Boiled Linseed and it helped dramatically. It also revealed my flaws, which is very important as I continue to improve refine this technique . My “go to” finish is 2 coats of clear shellac, then 4-6 coats of juice (1/3 each clear shellac,Denatured Alco and BLO) .

Sparks and Lane,
Thanks for the wise help lads
