Using Mortar as tiling adhesive?

[Steve91k]

hi, I heard the "old way" of tiling floors was to use dry sand and cement binding, and then a slurry of water and cement would be used to fix floor tiles into place?

I was a little taken aback by this suggestion, but would it be possible to use mortar as tiling adhesive on a floor?

I intend to use ceramic floor tiles and grout as usual, but I have not heard of this method before, can anyone shed any light on it?

quarry tiles yes, ceramics no.
