You make your own canvas? How big's your loom?

Anyway, is there a way to make your own cheap dryer medium? Quick answer is yep, sure is. Do you have any philosophical problem with toxicity or health issues?

Longer answer: 4-6 hours with true oil paints is asking too much I'm afraid, not consistently at least.

Drying time is dependant on the nature of the original pigment(s), the type of oil used as a binder, how thickly you're painting, temperature and humidity, your support and its preparation and maybe some other factors so to get this kind of drying time as it is would be tricky (and would be very risky to the painting) and across the board is just not feasible.

If you paint thinly on a fairly absorbent ground, using lean paints and minimal medium, and prefer colours made from pigments that naturally make faster-drying oil paints you'll get pretty good drying speeds already without having to resort to added driers of any kind. If you want to include modern synthetic organic colours or traditional oily paints like Lamp Black, which don't dry quickly by themselves, glaze with much body or paint at all thickly and you want short drying times then oil paint is not the medium to be using.

Some people are just going to suggest you try alkyd medium, alkyds instead of true oil paints, or maybe even Genesis heat-set paints where you 'dry' them at will with a heat gun.

Re: Is there a way to make your own cheap dryer medium

I think many of the established oil quick driers (like colbalt) have few, or only single, ingredients - so you'd still be paying about the same for the raw "secret" ingredient.

Also, any oil layer that dries in 4 hours will probably get sticky, gummy or skinned too soon in your brief painting session to really take advantage of the unique oil blending and manipulation techniques.

If overpainting over wet oil layers is the only concern, best bet is to buy, or whip up, some "thixotropic" medium (maroger, some alkyds formulas, etc.) that will will allow light overpainting w/o disturbing the underlayer much.

If quickly moving from wet blends to total, ready-to-hang drying is what you're after, then Genesis is for you.

Re: Is there a way to make your own cheap dryer medium

Hello Boogie, and welcome to the Oil Forum.

Einion is right that dry in 4-6 hours is unreasonable for oils, but niether do you have to wait for days.

Here are a couple of threads for your review:

Classic Oil Painting Mediums
Glazing Tutti Fruity

As already mentioned, so much depends on how you paint in the first place, and the nature of pigments themselves. Even if you give alkyds and other driers a whirl, it's important to keep in mind that you can't push the river - oils are what they are.

You might consider having several paintings going at a time so that while one is drying, you work on another. Or, since you favor a hands-on approach to your materials, you can be stretching/priming canvas, doing study sketches, imprimaturas, underpainting, etc., while waiting for your work to dry sufficiently.

cheers!

I've seen a lot of recipes for making your own art materials, but I've never come across one for making lead napthanate or cobalt linoleate.

But think about this. You can get enough siccative to last you for months for less than $10 US. The time, effort, and materials cost involved in learning to make your own siccative would be ridiculous compared to the cost of just buying a bottle of the stuff. If you want to economize on art materials by making your own, then your efforts would be most efficiently applied to other materials, such as grinding your own paint.

David Rourke may be a better authority on this, but I've found an egg & oil medium to dry very fast. Recently I've been experimenting with methylcellulose as well which dries to touch in a few hours. They're both extremely simple to mix yourself.
