How to hold a paintbrush

Technique is one thing; the zeitgeist is another.

Dry Wash, painted earlier this year, is most indicative of where I’m going right now, but I didn’t even include it at the event where I painted it. Oops.

Last week I showed Roger the proper way to hold a paintbrush. “At its end, like a baton,” I said. “Not like a pencil.” I demonstrated how much more swing you get when you hold it like that.

Of course, there’s no one right way to hold a paintbrush. It’s just that every new painter thinks of it as an extension of their pencil and clutches it up near the ferrule in a three-finger choke hold, as if they’re about to work on their Palmer Method of Penmanship. That was adopted because it was hyper-regimented and would improve discipline and character. It was even believed it could reform delinquents.

Holding a brush like a pencil gives you a lot of precision but very little range. Holding it like a baton at the end gives a lot of lyrical movement and less precision. You can do both, but you’ll have much more energetic brushwork if you start off with it held farther back.

Roger’s a thoughtful guy. “This is all part of the idea of working in big, broad, patterns, rather than focusing on the details,” he mused.

I don’t remember where or when I painted this, but I like it today. It’s almost impossible to judge change in real time.

Yesterday I wrote about alkyd media and glazing. I got an interesting response from Bruce Bundock, a fine acrylic painter who works as a preparator at the Frances Lehman Loeb Art Center at Vassar College. “Seems to me painting is the one discipline where there is no ‘last word.’ It’s what works for each individual,” he wrote.

Technique is one thing, the zeitgeist is another. The majority of painters since the mid-19^th century have worked alla prima, directly and expressively. Glazing has no place in that system.

Painting movements are pushed along by both culture and technology. The Pre-Raphaelite Brotherhood was born in Victorian Britain. Queen Victoria’s early reign was marked by rapid industrialism and social and political upheaval. The nostalgia of its painters was reactionary, an effort to cope with overwhelming change.

The Impressionists were firmly grounded in technology. The vivid synthetic pigments that characterize their work were developed in the 19^thcentury. They were able to paint outside extensively because of the invention of the paint tube in 1841. Emerging color theory shaped their thought.

Our own times have been rapid and anxious, which is reflected in our direct technique and in Expressionism. However, a young person would be a fool to tie himself to the last century. Nobody can predict where the spirit of the times is heading; we can only swim like mad and chart an uncertain course between fickle fashion and the past. And that is, as Bruce said, highly individual.

Alkyds may be the technological advance that ushers in a new period of indirect painting. After all, the Pre-Raphaelites were living in tumultuous times, and they glazed like mad. If you’re painting glowing, detailed interiors like William Holman Hunt’sThe Lady of Shalott, you’re definitely going to hold your fine brush like a pencil.

Wildfire, western Canada, painted during my 2016 road trip. Change isn’t always pretty.

But that’s not where we are today, and all I can do is teach my students the best technique rooted in our times. “Why didn’t you ever tell me this before?” Roger asked.

“I really thought I had,” I said apologetically. Painting instruction is so individualized that you can easily miss something like that. “But I’m still not refunding your tuition,” I added.

That was my last local (Rockport, ME) class of the summer. We start back up in October, on Tuesdays from 10-1. If you want a place in that session, email me.

There’s nothing new under the sun, and that includes glazing

Is it true that the fat-over-lean rule is suspended when using alkyd paints and mediums?

Grain Elevators, by Carol L. Douglas, is an example of a cold-wax medium painting. I used it to add the rough texture of a beaten down industrial setting to the sky.

Oil paints are pigments suspended in vegetable oil. These drying oils are most commonly linseed oil but also may be walnut oil or tung, poppy, or perilla seed oils. They do not dry by evaporation, but by oxidation. To speed up the drying process, metal salts are sometimes added.

In my youth, we made our own medium with equal parts linseed oil, turpentine, damar varnish and a few drops of cobalt drier. After seeing the condition of some 20^th century masterpieces, cracked and brittle after less than a century, I stopped making my own and started to use commercially-prepared medium instead.

Alkyd mediums have almost completely taken over the industrial coating world. They dry more quickly than old-fashioned drying oils. There are many ways to make an alkyd medium, but they all involve cooking a vegetable oil with a polyol like glycerine. Before you consider eating the results, however, alkyds generally have Xylene added to control the viscosity. Alkyds for decorative painting have extra oil cooked in to lengthen the oil strands and to make a more durable finish.

The Sacrifice of Isaac, c. 1527, by Andrea del Sarto, courtesy of the Cleveland Museum of Art, shows a painting at the pre-glaze point.

I’m seeing more and more students come to class with alkyd-based products like Galkydor Liquin. I’ve used both and like them well enough; they don’t feel significantly different from conventional media. But I’m skeptical of replacing something proven with something unproven to save dry time, which is relatively unimportant in alla prima painting. Classic painting mediums last for centuries when properly applied.

It’s claimed by some teachers that alkyd media allow you to ignore the fat-over-lean rule in painting. That’s the principle that higher-oil paints (i.e., mixed with medium) belong on the top levels, whereas lower-oil mixes (i.e. cut with turpentine or OMS) belong in the initial underpainting.

The Sacrifice of Isaac, c. 1522, by Andrea del Sarto, courtesy of the Prado, shows the same subject in what del Sarto would have called its finished form, after meticulous glazing.

Pigments affect the dry time of paints as much as the oil binder does. However, as a general rule, the more oil, the longer it takes for paint to dry. The less oil, the faster the paint dries, but this produces a more brittle film. That’s one reaason we use thin layers at the bottom and save the juicy paint for the top.

There’s been a trend toward painting techniques using glazing layer after glazing layer of thin pigment dissolved in alkyd media. I’ve even seen paintings done by laying down layers of alkyd medium and then painting into that. None of that is proven technology, and won’t be in our lifetimes. It will take another few generations before the durability of indiscriminate alkyd glazing is proved.

Self-portrait, c. 1655, Rembrandt van Rijn, courtesy Kunsthistorisches Museum. His technique involved painting impasto passages above transparent ones, or the opposite of glazing.

Glazing has been used since oil painting was invented. It was traditionally done by applying transparent colors over an opaque monochromatic grisaille or colored foundation. That doesn’t mean the masters just indiscriminately glazed everything. Most passages were painted alla prima, just as we do today. Glazing was restricted to dynamic passages and fine modulations.

To do it right is very tricky; I’ve never mastered it. It’s hard to predict how a passage will look when dry. You get no second try at the underpainting, so if it’s wrong, too bad. And the thickness of the glaze affects not only the paint’s tonal value, but its surface finish.

Still, pigment suspended in a binder is very beautiful. If you’re interested in this effect, you might try cold-wax mediuminstead. Unlike encaustic, which uses heat to thin the wax, cold-wax medium is whipped with mineral spirits. It has a milky, soft, appearance. You can sand it, scrape it, and rework it to your heart’s content, and it’s thoroughly modern in its final appearance.

There just might be something to this.

Early spring morning, Piseco Lake, oil on canvasboard, 12X16

Yesterday, I wrote about a Stillman & Birn Alpha Series sketchbook that Jamie Grossman gave me, and my first attempt to pre-sketch my paintings in it in watercolor.

This morning as I walked my appointed rounds, I carried the sketchbook and watercolors instead of my camera. The first thing I noticed—of course—is that it took rather longer to make my circuit than it usually does.

I’ve had my eye on this lovely house set on a hill for a few years, and there being a convenient bench, I sat down to sketch it. (I decided that it will be a better painting when the leaves are leafed out.) From there, I moved to a tree in the deep woods with a triple trunk, which proved to be very difficult, but which was good observationally. In both cases, I was approaching the project too much like real painting, which just irritates when all one has is one small brush.

My sketch, a bench.

This last sketch I did much more quickly, just ripping off a pencil drawing and then flooding the sheet with a color map. And it is frankly more satisfying than either of my earlier sketches (which you can’t see because I finished my day after dark and forgot to photograph them).

Because I didn’t have a toned canvas, I decided to underpaint my finished study in alkyds. (By this point, time had ceased to be a meaningful constraint.) And it was a good day for them, too—the wind whipping off the lake dried them in no time. My alkyd painting is a simplified but direct rendition of the watercolor sketch.

In the end, this painting took me about four hours, and that is about what I’d expect for a field sketch of this size (12X16). So whatever time I spent on the watercolor sketch was saved on the final project.

Marilyn Fairman has joined me in the hermitage, and we spent the afternoon painting intensively. Tomorrow, we have all day to paint. What a joy that will be.
