The don't believe any of these are watercolor. The ones that are thick are oil.
Ah, I kept my machine so clean. How nostalgic.
Edit
Okay actually, I take that back. The quin purple or magenta is watercolor. I NEVER made an oil batch that large and just let it slide down that way - it has to be watercolor. Watercolor grinds were way faster except for hematite.
