Bucket of copper crap

Try stabilizing one and see what happens.  The red stuff on the closeup one looks soft.   Better wash it good.   

I see a few pieces that would definitely be worth working. Most of it though looks like surface coatings.

There is some malachite, such as that one towards the bottom right. That nice blue could be a couple of things including turquoise. A hardness test can help narrow things down. Actual chrysocolla is very rare and softer than most turquoise. "Silicated chrysocolla", which is actually a chalcedony and not chrysocolla is harder than turquoise.

And veins and stringers can look really cool in cabs, like these turquoise stringers in a purplish quartz.

I freakin' told you it looked like turquoise!! LOL

How would someone stabilize this?

I am curious about this too! Some of my turquoise is natural and I don’t have a vacuum chamber. Guessing that the old epoxy method is considered low quality for higher end materials?

Not all turquoise needs to be stabilized.  I have only stabilized one piece of mine, a chalkier piece, just as an experiment of a stabilization method. The rest I just cabbed without any problem.

Ive been there a time or two. Happens to the best of us 😂

Most looks like good old "crumblecolla", but there were a couple worth playing with, kinda resembles rawley mine material, but lots of places have stuff like that. In fact, I was pulling buckets out of my cargo box yesterday and pondering where in the landscape one of them should go.
