A two-page article from The Melliand by Dr. Nüsslein on using Nekal BX dry, a wetting agent, in the indigo-hydrosulphite-soda vat for dyeing cotton. It reports on how Nekal changes the vat's appearance, the particle size and filtration of precipitated indigo, and the effects on vat stability and shade depth at different concentrations per 10 gallons. The text ends with "To be continued"; two photographs show dyed nettle samples.
