Indigo Fermentation – Day 5
There are bubbles! I now realize that temperature is critical. I think I had let it cool down too much the first day and then let it get too warm. I can see why in the video I watched the vats were sunk into what looked like a cement floor – no doubt this keeps a very consistant temperature. I also talked with Chris Dalziel of Joybilee Farm, who had tried a fermentation vat using the Madder, soda ash method and this was also her observation. So far I have used the hit and miss method – perhaps a thermometer would be helpful!
