A 1889 article in Science, reporting from the Paris Exposition, on Comte de Chardonnet's process for making artificial silk from cellulose. It explains how natural silk is formed, then describes nitrating paper pulp, dissolving it as collodion, forcing it through capillary tubes, and denitrating the filament. It describes the three demonstration machines, compares cost and strength with natural silk, and mentions fabrics and a chasuble made from the product.
