I must add some gloss to the pigments. I'll paint the next layer and the rest of the painting with an Gamblin Galkyd, an alkyd resin oil. Alkyd resins are polyhydric alcohol with polybasic acid. These alkyd modified resins are non yellowing and dry faster than natural oils. Liquin is another alkyd resin with added oil.
Alkyds mix well with normal oil paints and speed drying.
I love it . Alkyd oil has some of the same qualities as water based acrylics and some of the best qualities of oil. In acrylics I blend and glaze in layers because the paint dries so fast. I gave this oil painting painted so far without medium a thin coat of alkyd oil and let it dry. This alkyd oil is one that is not premixed with any other natural oil to slow down the drying time, and so letting it dry and be repaintable and unresolvable again within three hours.
