Pretty cool! I tryed to get some black jack from my suplier but it was fairly unstable and crumbled while grinding on it. So he steered me away from that batch. I have enjoyed your videos so far thanks for filming them.
I have a black jack that chipped while I was unboxing… I will soon try to cut it! As you say, some batches may be unstable! Thanks for watching my videos 🤩 tonight I will edit the 2nd part and post it tomorrow ☺️ take care!
