Iceboat MaryEllen, gouache. The 50/50 isopropyl/water dilution stayed liquid at 15° F/-12°C, but caused some sedimentation in foreground, which helped in this case.

Reactivation test: cad yellow / ultra blue, overpainted with water. 

Iceboat Vixen, gouache over casein from a photo.

Early stage in painting with light passages only. Darks came later.
