ok everybody..heres the deal. daniel gave me an idea for a science project this year for cp...i still have to run it by cp it is basicly using super glue...opticon...and jamies recipe to seal some stones...and polishing and comparing results...sounds cool to me. anybody see any drawbacks to this project?.....we will need 3 or 4 slabs of material that needs to be sealed.....what material would someone recommend?....i have some of jamies Chrysocolla is that a good candidate. throw ideas my way...yays...nays for this project...kev.

I think chrysocolla is a good candidate as it is often porous and will allow the stabilizer to soak deep into the material. I am doing a similar experiment right now. I used plain ole' super glue to stabilize some and an acetone/epoxy mixture on others. The difference is time. The ones stabilized with super glue can be used fairly quickly while the ones in acetone/epoxy have to soak in the mixture for around a week and left to dry for another week.

sounds good to me ---- might try some Morgan Hill Poppy jasper-- alot of it needs sealed before working -------- something I've wanted to try but haven't yet is like when they use it for finger prints --- has to be in a large sealed box , hang the stone above the super glue and heat it from below --- basically evaporates it so should get in all the smallest of cracks but wouldn't want to inhale the fumes or anything like that ----------some turqouise and opals are others that need stabilizing too------

Sounds good Kev.
Montana agate is notorious for having cracks right where their beauty lies.I've never tried anything to seal them yet but it is on my very long list of "to do's" now that I'm retired.

some of that Mozarkite needed healing, let me look at what i've got, i can send you some science project pieces.

after some thunking with cp....he said healing fractures cant be so bad ;D....he didnt really want to do a rock thing....but healing fractures kinda got him going a little ;D.
we kinda decided to go a diff way.....super glue in the liquid state....and super glue in the evaporated state....thanks dave.
now dave...where the instructions ;D...or plans for the box ;D.
KD if you have a few small peices that you know need healing....yes i would like a slab or so...just pm me.
or anyone that may have a small slab we can cut....that you know needs healing ;D..
sheri....thanks but i think turgoise is a little out of our league...he will have to polish this himself........kev.

That experiment sounds good. The only limit, as I have found out, is how to get the material into the stones to repair the fracture. I use a commercial vaccum unit, a pump and bell jar, however if you use a laboratory aspirator and home made bell jar, you can get the same results. www.ishor.com/refining.htm#SimplicityAt the bottom of the page is an aspirator that works off tap water pressure, good for 28 hg. Also, epoxy thins with alcohol, not acetone. Acetone will colloid the epoxy. I think the test is a good one. Liquid cyanocrylate, opticon, T-28, all good materials for sealing fractures. Making a bell jar is easy. Have fun.

HeHe Cp is gonna be a rock doctor, healing all those fractures. Sounds like a cool experiment. Good Luck to you Cp and Kev. Tonja

o.k. so do i have him grind the 2 stones with the 120 wheel first?....by hand that is....bench grinder....and then try to seal it.
or do we try to seal 2 peices as cut off of the saw rough....then try to grind it?....we aint never tried to seal anything ;D....just the first question of many ;D....kev.

Rough the piece, then vaccum the sealant. It is not something people do all the time. Definately a father and son project. It works well on emeralds also. I have saved many a mine run emerald. Those are emeralds that have been blasted so they are real full of fractures.

A coworker/rock buddy told me about a way to get sealant into rocks without a vacuum. It involved opticon. You put the slab in a glass jar with the opticon (I think) and stick the jar in boiling water on the stove. Then you seal it when you are ready, just like canning fruit. The vacuum that seals on the canning lids is what gets the opticon into the rock. Has anyone ever heard of this? Maybe this would be part of your experiment if you can't get a bell jar, but I have no idea if it works. Steve
