Can you expound on this? I would like to know more! I had thought that
with my future horse barn, it would be great to have a clay floor
(without stabilizing with cement), but I thought it would be impractical
due to horse urine, etc. Maybe it is anyway, but could you explain the
percentages used and what the magnesium chloride does?

I love how the list has come alive in the last few days!
