This Glaze medium from C.Roberson & Co can be used with Oil colour to produce thin glazes, aid fine detail work and smooth brushwork.

  • It increases the flow and translucency of Oil colour.
  • The inclusion of Strontium – a Cobalt dryer alternative, acts in speeding up the drying of Oil colour making up the perfect choice for those working with Oil in building up colour in successive layers.
