I’m new to collecting and have absolutely no clue how to date this. The front of the bottle is hard to see; it reads:
MILK OF
(Trademark)
MAGNESIA
THE CHAS.H. PHILLIPS
CHEMICAL CO.
GLENBROOK CONN.
The bottom says MADE IN USA with two dashes on the left side and an M on the right.

This is my new find. Coblalt blue bottle, over 13" tall and 5-1/2" in diameter. Partially threaded neck. M in a circle for, I believe Maryland Glass and 2 below it for mold#?. I had find out that Maryland made them from 1920 to 70. I look for similar bottle on the web but cannot find more...
