I’d like to try water-soluable oils for plein air. Cobra seems to be a popular brand but I just saw a YouTube video of an Aline Ordman workshop. She uses Holbein Duo Aqua and they look so creamy & smooth! They seem to be the priciest though.
Does anyone have a brand preference you’d like to recommend?
Also, for plein air, do you just carry water in a regular metal brush washer–or do you bring along a larger amount of water say in an old soda bottle or the like?
And what do you do with the dirty water? I recycle Gamsol so I’ve never poured it down the drain or out in the environment. Wonder if the water-mixable oils are any more harmful to the water supply than say washing acrylic paint brushes in a sink?
