Glue is a good question!

- E6000 for dopping (yeah, wax sucks)
- Hot Stuff for quick fixes and small cracks
- Epoxy 330 for intarsia and any type of permanent stone mating
- Harbor Freight 50/50 epoxy for glue-on bails and findings
- 3M Feathering Adhesive for polishing pads
- cheap wood glue for mounting end cuts to board for further dicing

I think that's it for my glue collection.

Try black powdered wood dye to color black about and glue used.  Google it - it is cheap and easy to find.

Even easier is using carbon from a candle -- I've been doing it for years.  Simply light a candle and hold a flat piece of glass over it until it accumulates some "lamp black."  Use a razor blade to scrape it off and mix it thoroughly with epoxy.  I've used it for opal and turquoise inlays and some pieces I did in the 1970s are still in great shape.  I use Epoxy 330 for that work.

Agreed but I am trying out GreatPlanes 6 Minute Pro Epoxy instead of my usual Loctite 5 minute epoxy.
The problem with the Loctite is the hardener goes bad before I use all of it.

The GreatPlanes hardener seems (so far) less reactive.

Both brands purchased in the larger double 4oz dispensers.

what is a solvent for E6000 and how long do you wait for it to cure before you cab?

    Be careful on stocking up on glue. Other than 330 Epoxy I have had a lot of glues go bad before I finish them. If you have a room that stays at a moderate temperature all year it will help. The worst seems to be instant adhesives. Even Elmer's will go bad, especially if it gets too hot in the summer.

I usually dop my cabs with E6000 and let them sit over night, but I suspect you might be able to start grinding with only an hour or two dry time.

Not sure on solvent, but I haven't needed it. It holds the stone just the right amount and when I'm finished I simply pry the stone off with my thumb. When E6000 dries it is elastic rather than hard like epoxy. Whatever glue still left on the stone can be peeled off. Just make sure your dop sticks are not too wide as the more surface attached the the stone, the more difficult it is to remove. My dop sticks range from 1/4 to 1/2 inch diameter.

Goof Off or any acetone like solvent will clean up the E6000.  A set up time of 24 hrs is best for it.  My local craft store sells E000 in tiny tubes so there's little waste (other than they are not much cheaper than the big tubes).  Go figure. 
I dop with cheap super glue from Walmart.  It releases with just a bit of heat (not enough to burn your fingers, but a bit of heat softens it nicely).  This stuff comes in packets of 4 or 5 tubs (black and yellow); don't use other super glues that are more difficult to release from the dop nail. 
Note that the carpenter's glue that we use to stub rocks onto wood stubs tends to be affected by freezing so I move my stubs into the house from my unheated shop in the winter.   I almost never have rocks pop off the stubs if they have cured 24 hrs, but in the winter its all to frequent if they are exposed to cold before properly cured.

I've finally given up on carpenter's glue and wooden blocks for sawing. Now, I use ceramic tiles or, even better, scraps of granite or marble from a counter-top manufacturer. Glue up my rough with super glue to the scrap counter-top and cut away on the saw without worrying about pop-offs or dishing a blade. Simply saw the end off the block when I'm down to my end piece and the remains of the block can be re-used, unlike oily wood. Also, virtually no curing or wait time when I'm setting up my stones and blocks.

While I'm at it, there are two more epoxies for you to consider. Hyxtal NYL-1 and XTR-311. I like to use XTR-311 to treat fine cracks in cutting material like Chrysocolla. It is virtually colorless and has very low viscosity. You can get very good penetration, especially under vacuum. XTR-311 takes about 36 hours to cure (faster with moderate heat) so you can have plenty of time to do treating or even do multiple batches of stones with the same batch of glue.

I use Hyxtal NYL-1 to glue quartz caps on opal triplets. It's also low-viscosity and virtually colorless. It will never yellow. Cure time is approximately 1 week.

Both of them are expensive, but they cut down on failures and bubbling. One nice stone can cover the expense of the glue.
