Thanks Kirk.  I'd never come across that before.  I'd only found that they
are the same.  Good to know.  I'll also point out for the oil absorbing
discussion that you can get a volume of clay sold to soak up oil from
places like Tractor Supply here in the states for cheap.  A little time in
the blender and you'd have a nice powder to try with the soaking or vacuum
trick.
