Terracolor 609B Borage Blue From £20.47

I've used this several times. I diluted with extra water (200ml) and it stopped it running. The longer it's dipped the lighter it gets.

Very runny- Don’t apply this more than halfway down the outside of a pot and put on a drip tray. You have been warned! It’s a lovely glossy blue colour with hints of green where it breaks over edges. Don’t apply too thinly or you get a disappointing brown colour.
