Hey All,
You can also try going to your local hardware/pool supply store and pick up
some pool-cleaning acid. It's used to raise the ph of swimming pools. It
usually runs for under $10 a gallon. I recently used some on a small nantan
(bought for the experiment) and it ate all of the shale off in less than a day. If
you try this, make sure to put the acid in a well ventilated place, as it
tends to make a strong sulfur-like smell as it works. It should etch slices
fairly well.
Anyone else try this stuff?
Jason
