The new smokeless powder, called Poudre B, was three times as powerful as black powder for the same weight and left virtually no residues of combustion. Paul Vieille soon became director of the "Laboratoire Central des Poudres et Salpetres" in Paris, where his research had taken place.
He then used roller presses to transform this gelatinized colloidal substance into extremely thin sheets which, after drying, were cut up into small flakes.

More-stable and slower-burning collodion mixtures were eventually prepared using less concentrated acids at lower temperatures for smokeless powder in firearms. The first practical smokeless powder made from nitrocellulose, for firearms and artillery ammunition, was invented by French chemist Paul Vieille in 1884.
