Given that I spend most of my time messing about in the studio with materials that would have been familiar to Rembrandt you might be forgiven for thinking that the Norfolk Painting School is a backward looking school, but you might be suprised.
In fact I've been looking just as hard at the new wave of modern pigments and materials available to contemporary painters and seeing how they can be used with
traditional methods.
Many of the new transparent earth pigments (transparent oxide red, yellow etc) are so finely composed in terms of their pigment size, that they let enough reflected light through the paint film as to almost flouresce in a glaze, particularly laid over a suitably reflective surface, such as smooth white impasto.
My new delivery of Neo Megilp from Oregon has given me an opportunity the Old Masters never had; to try an impasto application of these incredibly luminous pigments and the results are no less than staggering; for the first time in my career I can see how Turner might have began to get some of the luminosity into his skies using the same principles, albeit with duller pigments and a more challenging (being shorter) resinous megilp formulation. I'll be messing about with this stuff over winter to see what it can do on various test pieces.
On the subject of modern pigments another couple from Gamblin have impressed me recently; chromatic Black and Quick Dry White.
Chromatic Black despite its name isn't a black at all, but a very dark complimentary grey intended (just as Payne's grey) for the subtractive mixing of hard to find complimentaries. For those of you unfamiliar with the principal it goes like this.
Imagine you have a bright orange which you with to desaturate, if you put black in it it will go muddy, use white and it will go chalky, in both cases not only desaturating but taking on the character of the colour you mix, so while you can do it this way it's unsatisfactory.
If however you put a bit of blue into the orange (blue being the complimentary or opposite) the orange will just appear a little less orange, rather tham muddy or chalky - in other words it is desaturated.
Put more blue in still and eventually you will get a perfect grey that is neither orange nor blue, carry on and eventually you will get less and less orange until you get blue. So that in a nutshell is subtractive mixing - put opposites in to deaden colours: orange/blue, red/green, yellow/violet and so forth.
However finding complimentaries is easy with primaries and secondaries, but gets more challenging when one wants to find compimentaries of subtle mixes. The old standby for this was Payne's grey a kind of universal de-saturator which would desatrate a little less aggressively than black, but could easily kill colours if overdone. Davy's Grey was sometimes used as a softer alternative, but as a single pigment (Davy's is a mix) didn't work at all with some colours.
Chromatic black is a modern alternative, a perfect complimentary grey, made from just two colours, both translusent with small pigment particles that can be added more easily than Paynes to desaturate. It works very well indeed, and isn't at all bad as a glazing colour for shadows, certainly livlier than Payne's and capable of appearing deeper than Davy's.
Quick dry white is a little less impressive, I hoped it would be a good alternative to PW1 (Lead), which I use in block ins to create quick drying underpainting. QDW is a mix of Titanium and Zinc whites with the addition of an Alkd resin to speed up the drying of these tw pigments. Quick it is compared to these notoriously slow pigments, but its fat oil content rules it out as a serious alternative to lead for underpainting.
As a mixing white though it performs very well, having neither the hopeless brittle translusency of Zinc or the deadening opacity of Titanium. The alkyd in the tube also make it good for creating the kind of stable impasto that can be overglazed in time (although more time than lead).
When working with mediums it also seems to have some of the 'tooth' of lead, floating well over and holding on to passages of medium rich paint that leaner overpaintings would lift. Whether this is caused by the alkyds I'm unsure, but it does make it useful as a lead replacement for mid to upper passages.
Both of these pigments are available fom the Norfolk Painting School (
