If you use watercolours you usually find yourself in one of two camps: those who want as much control of their painting as possible and so hate granulating watercolours, and those who love the magic of granulating pigments, and the unexpected effects they create. For the first few years that I was using watercolours I hated the “cauliflower” and “graininess” of granulating watercolours and so I actively avoided those pigments. Nowadays I have several granulating watercolours on my palette (and two super granulating ones) and I enjoy the watercolour magic and pigment parties that they create.

A few years ago Schmincke started issuing “super granulation” watercolours, which are watercolours with extra pronounced granulation effects and two different pigments in the same paint – something that created a dual colour effect and added tons of texture to any painting they were used in.

I reviewed the first of those paints here, and since then Schmincke have come out with three more series of super granulation paints: Shire, Desert and Volcano. Of the three the Volcano interested me the most as it seemed to fill in a gap that the very blue and green leaning previous sets were missing: warm, red hues. As Schmincke watercolours aren’t cheap, and the full volcano set came out to more than I was willing to pay for just to experiment with, I purchased a trio box of 5ml tubes to try out.

The trio I got contained 913 Volcano Red, 914 Volcano Violet and 915 Volcano Brown. The one that I was most interested in was the volcano red. The one that I ended liking the most is the one that I had the least expectation for: volcano brown.

I filled three half pans with paint and let them dry out for 24 hours (Schmincke watercolours are much easier to pan fill than Daniel Smith as they come out of the tube better and they dry quicker). I then did a colour swab for each, and a paint test with three paint consistencies (honey, milk, tea as Marc Taro Holmes calls them): the first with very little water, the second with more pigment than water and the third with very little pigment. In the case of the volcano brown I overdid the water in the tea swab, so it’s much lighter than the rest.

Volcano red is semi-transparent and semi-staining, volcano violet is semi-opaque and semi-staining, and volcano brown is semi-opaque and staining. The opacity-transparency spectrum in watercolours is important if you mix watercolours, as the more opaque a paint is the less well it mixes and the more chance you’ll get a “muddy” mixture out it. It is also important for layering, as opaque paints will not layer as well as transparent ones. For this reason I use opaque and semi-opaque paints sparingly, and usually only during the final stages of my painting.

Staining is a measure of how easy it is to “lift” the paint off the page with water or by dabbing it off, should you need to. The more staining the paint, the harder it is to lift without leaving a stain behind (this also depends on the paper you use, of course).

Looking at the paints, the volcano brown shows dual brown and red pigments, the volcano violet shows red and purple pigments, and the red shows red and maybe orange pigments, but it’s hard to tell. The volcano brown is the most dramatic and interesting of the three, though the volcano red is by far the most granulating of them.

I tried to create a sketch using only these paints (on 100% cotton watercolour paper) and boy do they show their super granulating properties. while the volcano red by itself isn’t impressive, it does layer spectacularly well on the other two paints, and the volcano brown adds a lot of interest and drama to the painting. Of the three I’m likely to add the volcano brown into the rotation, and perhaps, for certain effects, the volcano red. The violet would come in handy if I was working on portraits maybe, but otherwise it reminds me of potter pink: a pigment that is too washed out to be of any regular use in my palette, and not worth the space when it comes to keeping it around for mixing purposes.

If you’re just building your watercolour palette, these paints are not for you. However, if you have an established palette and a certain style of painting that favours texture and layering, I’d recommend giving at least some of the Schmincke super granulation watercolours a try. They are bound to result in something interesting and unexpected.
