Drawing for Students
Free Watercolour Demo, Silver Teapot
Metal objects always pose a special problem for painters in watercolour. The purists among us don't like to use a solid white to pick out the highlights, and beginners often avoid tackling shiny metal in still life paintings. Brass and copper are usually easier, as they have base colours - but what colour is a silver teapot? As with chrome, it depends. It depends on what surrounds the silver teapot. Is is being painted in natural daylight? Incandescent light? Fluorescent light or a mixture.
For this demonstration I've chosen a silver plated teapot lit by fluorescent light on a no-seam pale green background.
I'm using modern computer technology in this demonstration, but you can still achieve good results the old-fashioned way. I printed out an 8" x 10" colour shot and used it as a tracing source. Using 300 lb Arches paper, I taped the print-out to the paper and used artists' graphite paper to transfer the image, using a sharp 5H pencil. Note I kept the actual teapot close by for reference, plus the photograph and the mat in which it will be eventually mounted.
I needed a darker than usual pencil image in order to photograph this for you, so I gently erased the original before my final re-drawing of the image. Don't hesitate to turn the drawing and the reference photograph upside down to help draw difficult curves. This also helps in giving you a different perspective to the object you're drawing.
You must decide how much detail you want in your final image. If you want an impression of a silver teapot, and not a more representational image, you can leave out what you think you won't need. I've chosen an accurate drawing for this demonstration.
Now we're ready to paint. Here I always suggest a few moments of quiet reflection on exactly how you will paint this picture. Look at the teapot carefully (or whatever it is you're painting).
Look right into the object and see what is there. What is being reflected? What might be left out or emphasized to make the metal look like metal? Decide what areas need misket to allow the white paper to show through. What is the colour theme?
Thanks to modern computer technology we can now keep the original image up on the monitor for frequent reference. This helps if you simply cannot paint a still life in place. You may not have the room to keep it up for weeks, and the transmitted light from your computer monitor acts like a slide show. A computer isn't essential of course. You can paint from a photograph, a magazine or a calendar. The idea is to have fun.
In any of my paintings I usually start at the centre of interest, unless I decide the background or sky should go in first. There's no hard and fast rule. Here I started at the top and worked down. It's already looking like metal I think. I used a wash of Antwerp Blue and Brown Madder as my basic colour, with a little Sap Green to pick up the green background. Note the misket detail is in to help leave white paper for the main highlights.
Early in any of my paintings I introduce the mat I will eventually use. This always gives an immediate lift to the painting and seems to enhance the colours. It also gives you an added motivation to continue, and acts as a kind of cheerleader and shows you how far you've come. The bigger the painting the more need you have for anything which helps you keep going, especially if you paint alone with no input from teachers or other painters. Notice how the highlight along the top of the lid has been softened to make a diffused highlight.
Do this with a small, stiff oil brush, using water and a gentle scrubbing motion and dabbing with facial tissue. Don't overdo this technique or you'll damage the paper and subsequent colours will run. Experiment first.
Leaving the misket in place, the basic wash goes over the handle area, with a couple of darker places to emphasize contours. The darker parts are made from a mixture of Antwerp Blue, Brown Madder and Sepia. I mixed three shades from darkest to light. Once you've experimented with metal objects, you will begin to see where certain areas will need emphasis to exaggerate the contrast between highlights and shadows. This is really two-dimensional trickery. You must fool the eye into thinking-hey-this is metal. It's shiny looking.
Gently remove the misket area with masking tape or the special lifter sold for this purpose. Now you have white highlights to allow your illusion to take hold.
Now you add the darker touches to create the illusion of embossed leaves on the handle. Gently soften the extreme highlights with the scrub-brush technique, and go back in with more dark shadows.
Here the misket has already been removed and the base wash applied. A light sap green wash was added to pick up the colour from the background. Put the mat back frequently to bolster your spirits. Don't forget - this is supposed to be fun!
Two things went wrong at this stage: one was the accidental use of Turquoise instead of Antwerp Blue, which gave me a distinctly green shadow, the the other was painting over a place which should have been left white.
The wrong shadow colour was quickly corrected, but I had to lift out some colour to allow white paper to show through. Experiment with this technique first, but place some masking tape over the affected area and carefully draw in what you want to lift out.
Cut this out with an art knife and press in place as shown. Experience will teach you how hard to press; you don't want to damage the surface of the paper. Now use the stiff brush, clean water and facial tissue, to alternatively dab and blot. Then use a small hairdryer to carefully and gently lift off the mask.
All that remains is to re-paint the area that went wrong, soften up the highlights you feel are too hard, and it's time for the background. The finished result is suitably metallic I think, and of course these infuriating demonstrations always look easier than the really are! I can't be there in person to look over your shoulder, and even if I was, I could only help you so far. Ultimately you're on your own, and only through constant practice and experience can you perfect any technique. You're going to fail many times, but you will learn from your failures and each time get a little better.
Now comes the tricky part: the background wash. Lock the front door, draw the drapes, turn off your cell phone, banish the dog and the kids, and be prepared for a high-wire act. Put on a clean wash of water all over and paint right up within 1/16" of the painting. Then push the water right up to the outline of your teapot with a wet brush as shown. Be careful not to go over the painting or the background colour will follow the water and mess it up. You'll need a steady hand here and something to stop you smudging what you've done. Turn the painting upside down if it will help. OK - you can start breathing again now!
When the clean wash is almost dry, I used a wash of Sap Green with a touch of Brown Madder and Sepia. The colour followed my water wash and then I pushed the colour into the edge of the painting as shown. You'll notice the colour wash still glistens but you'll have to work quickly or you will have a double line showing when it dries. Practice this technique before doing an actual painting.
To prevent blossoming from the surplus colour along the edge of your painting, use a flat brush to carefully sop up the colour all around the edges. Your painting is very vulnerable at this stage, so move everything out of the way to let it dry. Use a hair-dryer if you want to speed things.
I added a little extra shadow at the base of my picture, using a stronger mix of Sap Green a touch of Brown Madder and Sepia. I blended this in with a slightly moist brush. After this was throughly dry I painted in that intense shadow just along the bottom edge, softened it with a moist brush, and sharpened up a few mid-toned reflections on the base.
OK - switch on your cell-phone, unlock the front door and let the dog and the kids in. You're done. The finished result looks nicely metallic I think, and although a single teapot is not a candidate for anyone's living room wall, the experience should help you the next time you are faced with painting metal in watercolours.
