The HO Scale Walthers Cornerstone Superior Paper Recovery Boiler House kit is a vital part of your layout's mill complex. Brown stock, the fiber and water solution produced in the Kraft mill, is concentrated in the recovery boiler via evaporation into a substance called black liquor. As the level of concentration increases, raw rosin is created, skimmed off the top, mixed with other chemicals and heated to produce tall oil. The tall oil is stored in tanks and shipped by rail or truck to manufacturers who use it in the production of glue, rubber, ink, soap and lubricants.
