I just mixed up another batch of the medium I use for oil painting. I seem to always loose or forget the recipe so I decided to store it here for safe keeping. This is a simple recipe with damar resin, stand oil and gum turps. I don't bother with dryers or other ingredients, too lazy.
You can of course buy a ready-made medium but they generally don't tell you what's in them and also I find something meditative about preparing my own. It's a method of procrastination that feels as if you are doing something art related - anything but actually face the risky business of painting.
The recipe for the medium I use is in the proportions 1:2:5. That is, one part damar varnish, two parts stand oil and five parts refined turpentine. This gives me the base mix and I pour some off and add a little more turps for the lean underpainting as required.
See the full recipe here... and feel free to let me know if you have a variation on the theme.
