I am constantly thinking of ways to categorize billheads. When I purchased a large group of billheads last summer another theme showed through - colors! I really like the colored paper billheads. I can only assume that business choose colors to stand out from the crowd. I would also assume that colored billheads were more expensive too. Billheads continue to amaze me. Just when you thought you'd seen it all a really exceptional graphic one shows up on ebay or a plain but historically significant one appears. I haven't given up my habit, soon I'll post some new additions to my collection. I have lots I am watching in ebay too - one I am particularly crossing my fingers I can get my hands on. Wish me luck!
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.
