summertime, and…

I’m redoing my indigo fermentation vat this weekend.  It’s been a while in coming.  I emptied it out (25-30 gallons) about 2 months ago when I was redoing a fence line that it sat along and it needed to be moved.  At  the time I was also having some issues with fruit fly larva in the vat and wanted to have a fresh start and see if I could solve that issue.

The vat will take at least a week to ferment to a usable state and in addition I need to receive an order of ground indigo from Cheryl at Aurora Silks.  Coincidentally, she is having a sale on the 1 Kilo size ground natural indigo and offers free shipping.  I only had 4 oz on hand so made the vat up with that to get it started and will add the rest of the indigo when it arrives in a couple of days.

I am adding a fine mesh cover to the top of the vat since the lid to this container is not a complete seal.  Additionally, I am making a large net bag to drop into the vat while dyeing to keep all the organic materials and sludge to the bottom and away from the cloth as I work.  It’s really only an issue when working with larger open weave fabrics which I seem to use a lot these days.  It saves having to pick out the particles by hand or resort to lots of water wasting rinsing.  Water is precious here.

When I disposed of the old vat I balanced the ph with some citric acid down to about 7 and used the liquid on the ornamental drought tolerant landscaping.  The rest of the sludge in the bottom I added to the compost and was ready to start again. This vat had been in use for 4-5 years.

I am adding some video of the process of this new vat to the student forum for the online indigo workshop I have in my shop.   Here is a little bit of day two progress…
