Segment TWO A B C - Indigo Extravaganza
See what's inside:
2 – A Reduction Vats Starting with Fresh Leaves
Just what is a reduction vat? Starting with the most basic approaches to extracting indigo pigment from fresh and dried leaves, we’ll explore the differences between high-pH reduction vats and pH-neutral dye baths – along with the hows and whys they work.2 – B Reduction Vats Starting with Pigments
Pigments come in many forms and from many sources. We’ll discuss the best sources for natural indigo pigment and which states are the easiest to employ. We’ll use the pigments we produced in the earlier session, 2–A, as well as commercially available pigments, to develop a variety of reduction vats while exploring the pros and cons of each.2 – C Reduction Vats Starting with Mystery Sources
In this session we’ll delve into accessing the inner child of several mystery indigo sources – including John’s Cow Pie Indigo vat (also known as Cry Baby Indigo). In essence, these will all be vats made from left over bits of this and that, including what may be considered the orphan children of the deep recesses of your studio refrigerator–sources for which we may not easily determine the volume of indigotin present in calculating the other ingredients crucial to a reduction vat.
