Imperfections of the cathode surface (scratches, dents, corners) cause different current density.
In turn, cause a higher deposition rate at that point, from then on, it snow balls to random shapes.
Combined with low voltage (IIRC you work with less then .75V) create Cauliflower like deposition.
Many other variables effet it as well, e.g. concentartion, temp' , pH etc'...
It is cool picture, anyway you look at it 8)

Yup I know it's copper, looks good. There can be so many variables in this process, for one the change in current as the process progresses or the amount of copper in solution, the amount of other metals in it. I have had it do the same to me but not gotten that big but I only ran mine for 24hrs. Made one small change and had a totally different result. I would say as long as your getting it and it's not taking a week to get it, it's good pure copper. Make some bars stamp them and sell on the bay. You could have them checked with xrf gun or do the resistance test if you know that one. I do not know for sure how to do the resistance test for purity, just read up on it a few months ago.

Hello rusty,
Obviously you have a "red (green) thumb" in copper-cauliflower-gardening. Congratulations!
Today copper is much more expensive, as it was 10 or 20 years ago. Thus, - if you are a passionate (even addicted?) refiner, - why not reuse it, because of it's big surface and high purity in upcoming cementations, instead of selling it and thus loosing it, without having taken further use of it?

I thought that was the exactly the way they should look, sometimes many smaller "florets", sometimes fewer, larger. It looks right to me.

Seems a shame to melt it down.
i wonder how much you could get, advertising it as a "Man-made copper crystal".
especially in the SF Bay Area, where there are a lot of techies with extra cash.
how much does it weigh ?

Rusty,
maybe cut starter sheets to look like animals, trees or something, and sell the fluffy copper animals, I guess you would have to get a can of spray laquer or they would be green animals soon, green trees would probably be ok.

Maybe you found a new art form that you could make more money in this wonderful GRF world
