Langridge Oil Mediums can be used to change the consistency of oil paint, rendering it more convenient for brushing or applying, or more suitable for the artists’ particular technique. Langridge Oil Mediums can assist the artist to create paint that is thicker or thinner, faster or slower drying, more transparent or opaque. Glazes can be added to oil paint to create thin, but permanent, veils of paint. The resin content creates optical depth similar to a colour varnish.
