Well, yes and no. It is in a dried hardened form, quite 'chunky', but broken up into smaller pieces and powdery where it has been banged around. When I get a new batch of it from the pigment supplier, some of the chunks are quite large and I can see that they fit together into a circular shape. It seems that some kind of indigo liquid was prepared, and then let stand to dry in the bottom of a container. This was then broken loose, banged up into smaller pieces, put into bags, and sold that way ... In the mortar it crushes up into quite a fine powder. > What do you use indigo for??

I use it when I want the colour 'indigo', or when I mix it with other pigments to get greens, purples, or browns ... It is one of the foundation colours of the traditional Japanese palette. > >(Actually, I should admit that I 'cheat', and keep some ochre and earth > >colours in my box.

Well, I put the word 'cheat' in quotes ... I was simply trying to imply that my skills at mixing colours are far below those of the skilled printers here. They really use an incredibly small range of pigments - and when you look at the ukiyo-e prints of the past, and look at the astonishing range of colour and tone there - well, to my mind anyway, it's just amazing. On one of my first trips to Matsuzaki-san the printer, I had showed him a sample of a particular red shade in a book illustration, and had asked "How on earth do you make this colour? I've tried and tried, but just can't find it!" He replied something to the effect that I had chosen the wrong verb - one didn't 'find' colours, one 'made' them. Then he looked at it for a moment, turned to his pigment box, and pulled out a couple of things. A bit of this, a bit of that, and then a dab of 'sumi' ... a swirl of the colour onto a piece of junk wood standing nearby ... then a quick impression on a piece of the 'test' paper that he keeps standing by ... He pulled it off and put it side-by-side together with the sample. Other than the difference from the fresh 'wet' glisten, they were identical. Bang on first time! And everytime no doubt ...

It is in fact Thymol crystals. You put about 2 crystals in one liter of water. I use distilled water. It is suppose to help with the mould problem. It is not a cure just a slower downer thing.

It is a good colour and one should stay with it. I can understand when you talk about the mixing of colours. It does take years...or better I say continual mixing on every occasion possible. I don't know if you have ever just sat down and played with colours. I have 2 reds, 2 yellows, 2 blues, burnt sienna, yellow ochre. The three primary colours reds yellows and blue range from a cold to a warm colour, which gives me lots of latitude to mix any shade I want all the way to black....Well almost black.
