Hi, All
I use a crock pot to dry my oils after underpainting the casting in acrylics, mixing the oils with a goodly portion of thinner, and applying a very thin coating of the oil paint to the piece. I set the crock pot on "low," leave the top slightly ajar, and do this in a well-ventilated basement area. My pot is on a timer, and the oils are fully dry and flat in about 6 hours. I generally paint something and leave it wet until I get it the way I want it; then I "freeze" it by drying it in the crockpot. I can then paint over it without fear of screwing up the underlying work. Thanks to Phil Kessling for this croc pot tip at a seminar many years ago. In the US you can find a good crock pot for very little money at a discount store, or haunt the local tag sales for a used one.
Don't mean to spoil the fun, guys, but I DO NOT recomment that you dry paints in the oven or use any other device that you use for cooking food. My crock pot is used only for baking oil paints. As you may know, oils give off highly toxic fumes while drying and leave toxic deposits on ovens and utensils that are very poisonous. For example, the chromium in chromium colors is highly toxic, as is prussian blue. Even when using a light bulb, please be careful of the fumes as your piece dries.
Happy painting!
