Oh, I see - this is much more clear than the other thread. Mars is just another name for iron oxide, but if you want to stay away from oxides, that is fine.
Do what you have outlined sanding also - will give nice effect. make sure you let it dry between coats completely. then before applying the glaze - seal it with any plaster sealer to stop from absorbing the glaze.
Then glaze avay like you would glaze a regular wall.
The only "problem" (traditionally true marmorinos were waxed and polished) I can see is that you will not have matte surface, but you can apply matte top-coat or deglosser afterwards.
