Instead of the old-fashioned method of using wax for polishing floors,
etc., soluble glass is now employed to great advantage. For this
purpose the floor is first well cleaned, and then the cracks well
filled up with a cement of water-glass and powdered chalk or gypsum.
Afterward, a water-glass of 60 to 65 , of the thickness of syrup, is
applied by means of a stiff brush. Any desired color may be imparted
to the floor in a second coat of the water-glass, and additional coats
are to be given until the requisite polish is obtained. A still higher
finish may be given by pummicing off the last layer, and then putting
on a coating of oil.
