Paint, Color, and Chemical products were added as product lines along with the French Window Glass product line and their business grew rapidly. In August 1857, a product line that would change the future of H. J. Baker & Bro. was added -- Castor Oil. H. J. Baker & Bro. produced the Castor Oil which became common in household medicine chests across America. This, in turn, led to the first fertilizer product offered by H.J. Baker & Bro. -- pomace, the by-product of castor meal.
