Indigo Extravaganza! Segment TWO
THREE SESSIONS, two hours each, covering a broad range of reduction vats and using your home-grown, fresh-leaf indigo with minimal waste.
Saturday, August 31, 11:00-1:00 and 2:00-4:00 California time (Pacific Daylight Time)Tuesday, September 3, 11:00-1:00 PDT
At the end of each session, you will be given links to that day’s Zoom recording to download along with access to material specific to this class. In addition to the Zoom recording, I’ll be uploading higher quality vid-clips to allow you to see what I’ve presented with greater detail and ease. These clips will be available on Vimeo all the way through the last class and one month beyond – allowing you to access them as often as you like to work at your own pace. There will be plenty of time for questions and answers during class.
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. |
