Well! What can I say!!
I have only just posted the last post, if you see what I mean. It's been a draft for several weeks! I made the vat as described, but it wouldn't ferment! (Lots of exclamation marks, going on you will see, that's how frustrated I've been!!!)
I tried stirring it every day, to move the sediment from the bottom. I have "fed" it more sugar, more yeast. Not to mention that it is sitting on a heat pad to keep the temperature constant, as it had been rather cold here in Derbyshire in the UK.
Jim Liles book, The Art and Craft of Natural Dyeing - Traditional Recipes for Modern Use, suggested that if it hadn't become active in 2 - 3 days it may never do so! Well, I didn't want to abandon all the effort, not to mention, indigo and ammonia, I had put into it. So, I have given it another chance, adding more sugar every day and more yeast over the last two days and Hay Presto! it's started to ferment. I suspect it was because the temperature has risen, here, over the last few days, to be rather unseasonly warm at night. This despite the heat pad, has maintained the temperature a little more consistently.
Let hope this continues, as I have usually used a yeast and washing soda vat, and only used this one because some one said they liked it better! It has been a very good learning curve, though!
