With shredded cotton being blown in from the Cotton Dry House, 32 pounds of cellulose fiber were mixed in stainless steel nitrators that contained 1,500 pounds of nitric and sulfuric acids that were blended together. The treated nitrocellulose and spent acids were then discharged from the bottom into centrifugal wringers that removed most of the acid through the exterior of the wringer. The acid was used in the production of pyrocellulose or fortified for reuse. Wet nitrated cotton was then immersed in water and the slurry transferred to the Boiling Tub Houses.
