Any thoughts on this? Not sure if the original sent from my Blackberry went
thru with the photos.

I plan next week to slurry, or buff in with black grout with additional
black oxide powder added, to try to stain it black inside the pores, OR in
might try some aluminum oxide with the black oxide powder and buff it in
with a floor machine (don't have any tin oxide and no idea where to get some
here).

BTW. This is more like basalt, or actually IS a basalt, as opposed to the
American "bluestone" which is more like a quartzic sandstone.

Have a job to do, or maybe not... It has some light colored spots which look
like etching, but the finish is not burned. The floor went in before the
limestone walls. My guess is that it is grout from the walls which went into
the pores of the bluestone. This would make it impossible to scrub off and
pressure washing will probably not do it either. Not sure if it is acid
sensitive, tried to 5x and not much happened. What is this stuff?
