In a recent lot of paper I purchased, I stumbled upon two very colorful and pretty women's hair net packages. There may be a an ick factor as to what is inside package (real human hair) but the advertising outside is very pretty for these. From what I have seen on Ebay, they can be had rather cheaply.
In 1843 the first modern version of baking powder was discovered and manufactured by Alfred Bird, a British chemist. In 1846, Justus Von Liebig in Germany experiments with yeast made from sodium bicarbonate and hydrochloric acid with explosive results. In 1885, Eben Horsford and George Wilson manufacture chemicals which eventually became the Rumford Chemical Works. Horsford formulated and patented Rumford Baking Powder, the first calcium phopshate baking powder. In 1889, William Wright and chemist George Rew developed a double-action baking powder marketed under the name Calumet Baking Powder. Below find some examples of baking powder billheads.
