I got a selection of alkyd oils from Jerry's Art-a-rama. They are,by brand name, CAS Alkydpro.
They handle well and I could see their immediate applications for laying in a background color or blocking in colors for the next days painting; they'll be dry.
The remnants of thick oil on my glass palette had developed a crust overnight. In fact, the un-opened tubes need a pin prick to get the tubes flowing! After applying pressure to a new tube of Bismuth Yellow (a cool lemon yellow) I had a great quantity burst onto the palette. Fortunately, I had a trio of yellow abstracts nearby and they are enhanced and dry this morning.
I am using these pigments with Carol Marine's medium recipe.
