An International Correspondence Schools-style textbook section (§31) on carbonizing, the chemical removal of burrs and other vegetable matter from wool. It covers the sulphuric-acid, hydrochloric-acid, aluminum-chloride and magnesium-chloride processes, with solution strengths, drying temperatures and neutralizing. It also describes the compressed-air soaking apparatus, the carbonizing duster with crush rolls, and Sargent's low feed attachment, and carbonizing of cloth and rags. It ends with examination questions.
