That when the cartoon was laid on the surface of the support the linear pattern was transferred by dabbing or pouncing the perforations with a muslin bag of powdered charcoal the dotted contours traced through were then fixed in paint medieval tempera painters of panels and manuscripts made lavish use of gold leaf on backgrounds and for symbolic features such as haloes and beams of heavenly light areas of the pounced design intended for gilding were first built up into low relief with gesso duro, the harder less absorbent gesso compound used also for elaborate frame moldings background fields were impressionist often textured by impressing the gesso duro before it set with small carved intaglio wood blocks to, create raised pimpled and, quilted, repeat patterns that glittered when gilded leaves of finely beaten gold were pressed onto a tacky mordant adhesive compound or over wet bole reddish brown earth pigment that gave greater warmth and depth.

Applied with sable brushes in successive broad sweeps or washes of semitransparent tempera these dried quickly preventing the subtle tonal gradations possible with watercolour washes or oil paint effects of shaded modelling had therefore to be obtained by a crosshatching technique of fine brush strokes according to the italian painter cennino.

Rubens and diego velázquez however used oil pigments alone and employing a method similar to pastel painting applied them directly to the brownish ground with which they had tinted the white priming contours and shadows were stained in streaks and washes of diluted paint while lighter areas, were created with dry opaque scumbles, the tinted ground meanwhile providing the halftones and often remaining untouched for passages of, local or reflected colour in the completed picture this use of oil paint was particularly suited to expressing atmospheric effects and to creating chiaroscuro or light and dark patterns it also encouraged a bravura handling of paint where stabs flourishes lifts and pressures of the brush economically described the most subtle changes of form texture and colour according to the influence exerted by the tinted ground through.

Darken while. Cracking blooming powdering and flaking can result from poor priming overthinning with turpentine or the use of varnish dryers and other spirits colour changes may also occur through the use of chemically incompatible pigment mixtures or from the fading of fugitive synthetic hues such as the crimson lakes used by pierre auguste renoir, watercolour watercolours are pigments ground with gum ic and gall and thinned with water in use sable and squirrel camel hair brushes are used on white or tinted paper and card three hundred years before the late th century english watercolourists albrecht dürer had anticipated their technique of transparent colour washes in a remarkable series of plant.
