Vat Revisited

I forgot to say that the jar in which the vat was made holds approx 2 litres and I filled it to about 75% of its capacity. I apologise for the two photos being marked 'Left' and 'Right' being on top of one another instead of side by side, but however often I move them back to where they should be, save them, blogspot moves them back again........

This morning the vat is cold but still at pH 11, so I will try again but it won't be till this evening. In our south west facing, double glazed conservatory, it may well warm up by itself during the course of the day.
