How does Fat over Lean work with this?
Just started doing this with my last painting but am wondering if this is the right way. I've been painting with cold-pressed linseed oil very thinly (stretching it out, then brushing off any excess) on top of a (dry) section of painting then painting into that linseed oil either thinly/transparently like a glaze or more thickly/opaquely like a scumble- and probably in-between like translucent too. I'm not using anything but the linseed oil and the paints. Its really easy to get nice soft blends this way, or alter colors. It's been fun.
But is this the right way to do this?
Is the glaze/scumble layer then really 'fat'.... And how do you make sure that the next layer is as fat or fatter? How long does a glaze layer like this need to dry before you put another layer over it (it seems to go through a time where it's kind of tacky and it's not a good time to mess with it)? If it's dry to the touch - is that enough? And can you only paint more 'glaze' type layers over it? Is it OK to 'scumble' over an area that was previously glazed (like if you need to make a correction)? Or would the scumble be leaner than the glaze?
I've been painting additional 'oiled-in' layers over top once the layer below is dry to the touch... is this sound? I'm loving this, but don't want to be abusing the technique!
