At the end of the 17th and the beginning of the 18th century there was a blooming indigo production in Curaçao. A lot of the plantations had planted indigo plants and had built indigo tanks to produce the indigo dye for export to the Netherlands. The dye was in high demand there.
I have simulated the indigo production process at a much smaller scale. The original process has been described in a old Dutch document "Brieven en Papieren van Curaçao en Onderhoorige Eilanden" (Letters and Papers from Curaçao and its subordinate islands). More specific in the "Memorie Om Indigo Zaat te planten, schoon te maken, te snijden, te slaan, en voorts tot Indigo te bearbeijden in manieren als volgt" (Memorandum how to plant indigo seed, clean, cut and beat the plants to produce indigo). This memorandum is part of book 204, part (folio) 39 - 41. Full source reference: Nationaal Archief Den Haag (A.R.A.) 2e WIC toegang 01.05.01.02 inventaris nummer 204, folio 39 - 41 transcribed by S. H. Vautier. The text is published in the Archiefvriend in June 2006. I will not translate the old Dutch text into English but will just quote the transcribed Dutch text. After each part of the original text I will describe the process in English as I repeated it in 2014 on a much smaller scale.
