I have made a large number of analyses of Royal Baking Powder, and have found it to be an absolutely pure cream of tartar powder, entirely free from alum, ammonia, and all adulterations and impurities. In leavening power it is of the very highest.
Charles W. Drew, late State Chemist, Minnesota.
In this market I find but one powder besides Royal made from cream of tartar. Royal is the strongest, purest, most economical.
H. H. Nicholson, Nebraska State Chemist.
I find the Royal to be absolutely pure and highest in leavening power.
Albert Menke, Arkansas State Chemist.
From actual analysis made by me, I pronounce the Royal Baking Powder to be the strongest and purest Baking Powder before the public.
