I have a piece of Blue John i have polished and polished but it has a few holes. I have purchased a vacuum chamber and am about to purchase some "cactus juice". Thanks to you, i now have a better idea of what to do. Thanks for sharing this.
Thank you for doing this video. You answered a lot of questions I was running into with the stabilization arena of no information out in the net. Thanks so much!
Thank you for this! I'm wondering whether you have to degrease your slabs prior to resin treatment beyond the usual soap and water to remove oil from the saw. I'm reading that stabilization of oily wood is problematic with this method and immediately wondered whether saw oil contamination has given you trouble.
Hi, just got the message. That method will work really well on pietersite. I do the stone until almost finished then stabilize, then maybe the last two or three wheels.
Hi, i'm not sure but I use a small 3cfm pump and that works well. You have to give it enough time for the air to work its way out of the stone. If you can see into you chamber you can tell when bubbles stop coming out. Thanks for watching

Did it work?
I read that Blue John starts to lose its color if heated to 100-300 C.
300 being where it loses color completely

Very Very useful ,interesting, and necessary. Thank you
Very nice video Dave!! Keep them coming :)
good video, just got equipment to stabilize and your video was very helpful. going to run first batch of Petoskey stone today.
GREATLY appreciated sharing your valuable skill and work..
I appreciate that!
Who keeps the metric system down?
We do. We dooooo.

Sometimes when I'm selling someone will stop and sing that song. I love it
Wow ! Love the finished product!looks gorgeous. How would you stabilise flourite? I have a piece of blue john i wanted to polish for my girlfriend.
I don"t think flourite would stablize or work for lapidary. Most i know of wouldn't anyway.
Thank you so much Dave this was a awesome video :) can you send me the link to the vacuum pump and pot you used in the video
Sorry, don't check my comments. I bought the system from aliexpress. don't remember the specific store. All works still.

I clean them really well and on some rocks I wash a bit with acetone just to make sure the oil is removed
thanks
Thanks. I'm about to try this with some very fractured pietersite.
Can you tell me what rock you are stabilizing as I can't quite catch the name?

What Vacuum Rating will work best for stabilizing these? Would something rated at 29.9inHg @ sea level / 24.82 @ 5000ft work? Thanks!

You need to redirect your question to a forum on vacuums. Not hobbyist geologists. And in answer to your question, yes. More than enough.
Can this soft material be tumbled after stabilizing?
soft material is difficult to tumble. Only put it with other soft material and maybe skip the course grit and shorten the times
I just tried this with mecican turquoise chalk...total failure
