OK, the azurite looks good. SOME of the chrysocolla looks ok- others are a strange shade of blue green. We'll see after the fresh water soak and oven. I have high hopes at the moment.
The pic doesn't show the questionable ones. |

They look good. If the questionable ones still look questionable after the water soak, I wouldn't worry to much. Most likely it will be surface only. You can test to see by just running a spot of one under Gene.

Yeah, I was thinking it would probably grind off, but there is a risk the color gets messed up all the way through. It was the softest stuff. But, I feel pretty good with it right now. |

I've used Simple Green undilutede on my concrete driveway and it didn't turn the porous concrete green.

I'm afraid to suggest anything - but a vinegar soak or a bleach soak came to mind to try  But I'm NOT suggesting it & I deny all responsibility.  Patty |

The fresh water is turning a dirty pale green, so some of it is coming off. I'll get a pic later. I have hope. |

This is in the shadows a little, but you can see the water is far from clear anymore. I'm gonna pull them out and add fresh water.

I wonder if warm to hot water would make it work faster ?

I think I might keep doing it (and changing the water) until the water stays absolutely clear.

I touch of chlorine bleach in the rinse is what I use with light colored porous materials after cutting in old discolored saw oil, when I forget to save them for fresh oil. Works pretty good.

I'm getting tired of waiting, so I decided to try some art resin on that really desperate piece of pulsite. I doubt it can be saved. It's on a coffee warmer under a light bulb. In a couple hours, I'll flip it over and do it again. It ran straight through that big crack on the bottom. I may be able to save a small cab out of it. This was just for grins and giggles. I have no high expectations.

Not "poo-poo'ing" what you've done...just thinking out loud. I can see the AR holding the slab together in order to cut preforms...but I'll be curious to see if the AR has any effect other than that. In my head, I imagine this material has space between the "parts" which is causing it to be brittle. I would think this particular piece would be an ideal candidate for the vacuum chamber in order to try and impregnate those spaces within the piece, thus strengthening it in its entirety, rather than just the top and bottom.

For some reason- some how- that slabbette got crushed. It may just have been in the bottom of the bin. It has cracks that the CJ won't help. I could have used the CJ to help with porosity, but it would still have bad cracks. I would have to go back and fill the cracks with CA or AR. Evey time I touch it, a new piece breaks off. This was more out of curiosity than anything. I'm wondering if after the other side is treated if it will at least hold together. There is one small area that looks cabbable at this point. |

Nice big slab of Lucin variscite in there Thanks, it's the best one I have. I don't think it needed stabilizing, but the matrix is pretty soft. |

Well, Hell. I'm pissed. My oven was supposed to be here today. I was all ready to dry the slabs and test the temperature. My wrap teaching date was rescheduled, so now I have plenty of time to stabilize. NOT!!! No oven. It won't be here til Tues now. I ordered it on the 7th from Amazon Prime. What gives??
AND, the Art Resin didn't harden properly. I know I mixed it right right. I measured it.
Boo!
