Description
How I make Maroger medium
Maroger medium is a rich buttery medium used by some of the best artist today. There are a lot of myths and claims about this medium, it is my intention to dispel of few of these myths.

myth 1 it is complicated to make False there are only 4 ingredients.
myth 2 it takes days and days to cook False at most just a few hours.
myth 3 you can’t restore a painting using maroger, Wrong mastic is a gum, the solvents used in restoration are for varnishes.
myth 4 Mastic and Damar are the same False both are saps, but Damar is a resin, and mastic is a gum.
myth 5 Your painting will darken because of the lead False the lead used is an oxide, so it has already oxidized.
myth 6 It is complicated to use False mix a dollop into both your black and white paint, and some spread out like paint. Instead of using turpentine to make your paint flow, try some Maroger.
