Glaze
Glazing, applying a transparent coloured coating to an object to give it shine and freshness; in painting, the process of softening the impasto local colours of the underpainting by means of transparent layers and bringing them into harmony with the overall tone of the painting. See Glazes.
These Airfix Soviet Riflemen were painted Vallejo 70.924 »Russian Uniform«; the rifleman on the left is fully painted, but not glazed. The soldier in the middle has received a glaze of the single pigment colour PRIMAcryl 13.684 »Natural Burnt Umber« (PBr 7, iron oxide). His comrade, pictured at right, was glazed with the artist oil colour Lukas Studio 311 »Burnt Umber« a mixture of pigments PY 42 (transparent iron oxide yellow), PR 101 (synthetic iron oxide red) and PBk 7 (soot), which has left a conspicuous reddish cast.

The noticeable shine of the artists’ oil paint, caused by the »citrus terpene« solvent we used, will be eliminated by the final matt varnish.
