Hi Indcruz47
Yes please,!! Im sure most people love Malakite and would love to see your Photo
As regards the Stabilisation I'm sorry I cant help I'm sure some one else can,
If no one replies put your question on the general board It sounds like a very interesting subject.

have you tried Opticon, it's used to stabilize turquoise, and cracked slabs.

I have never worked malachite because I was told at a rock shop that the dust from the stone will make you fell like you have phonomia. Chest pains, trouble breathing, fever and coughing. I am not sure if that is true you may want to look it up. Has anyone else herd that?

Don't know anything about the stabilization question or inherent dangers associated with Malachite. I do know that "bob" is gorgeous. Please make more and post more pix.

Oh yaeh, you NEVER should work malachite dry, the dust not only makes you feel sick, it is seriously poisonous due to the high concentration of copper, so just don't go there.... |

There is not a problem with working malachite as long as you work it WET! Do not brush away dust, use a damp cloth to remove it. This should be followed with any copper based minerals.

If the malachite is chalky and pourous like low quality turquois you might try very thin Cyanoacrylate glue. I used to sell "Hot Stuff" and switched to Starbond as I heard it was cheaper and worked better. Both are water thin and will saturate turquois well. A friend tried pouring some on some turquois nuggets and had to pry them off the pan they were on. Most of the stabilized turquoise was treated with thinned down epoxy which is basically what opticon is. Opticon (a fracture sealer) requires the stone be very clean and cured with heat. Ihear two main comments; Opticon works great if you follow the directions exactly and Opticon doesn't work at all. I think the second group are the non-direction readers.

Definate DON'T grind malachite or any other copper mineral dry without at least using a 3M particle dust mask and if possible, always cut it wet just as a precaution. The dust is nasty and definately cvan't be good for you to be breathing in.  I was Dremelling some malachite in the kitchen sink with the water dripping and it still kicked up enough noxious dust to irritate my lungs. I'll never grind that stuff without a mask again.  |

I think I cut some today, I bought a huge chunk out of a pile of about anything you can think of and thought maybe this would end up being Malachite. When I cut it chalky was the word for it (wet of course). My reading this thread today could not have come at a better time for me, well here is what I cut, sorry for the saw marks was trying to do three things at once.  Yes? |
