If you place a drop in a sunbeam, does the drop dazzle like a ruby?

I am wondering whether you would get a redder (less brown) hue with cooking at a lower temperature.

Temps and times of your cooking?

A drop of varnish cooked at a lower heat will look ruby red. I've cooked many batches but that red is not equal to the thickness of a normal varnish layer. Sure it is red in a drop but on a normal thin coat of varnish it is still yellow.

Perhaps... adding a little red pigment will increase the red rather than adding a red pigment to a burnt brown colored varnish. I can probably agree with this unless you are referencing Roger's NO PIGMENT red varnish. But as others here have recently mentioned, Roger first colored the wood with a dark stain and then applied his long slow cooked ruby red varnish.

So getting the right color into the wood is the key. I have always known this but it is easier said than done...ask Don Noon how easy it is to varnish torrified wood. I know from experience with his wood that varnishing is a piece of cake....and beautiful. No offense intended Don.

If you mean like this color, then yes.

It gets somewhat browner if the temperature is raised, but not much different between final varnish. The "red" is still there.

I think it is mostly what type of colophony you start with and how much you reduce it. The one I have wouldn't cook 100 h at low temperature because it has already been reduced.

I have to gradually raise temperature to keep it fluid.

BTW, Roger's varnish is not that red! Sunlight and cameras aren't telling the real colors, red is pronounced too much.

Ex. Different light of the same piece (page 37)

 1. Direct bright halogen, 2. Inside lighted room close to small table lamp, 3. Outside cloudy day

Super colour - how does it look between 2 glass slides?

I haven't tested, it would probably be totally transparent like just 2 glass slides, if I dilute it and squeeze them together ;)

A lot of testing and reading, haven't been taking pictures, most of the test were failure.

As there have been little or no sun I have to imagine how much darker it would be with tanning.

Also got some help from a friend on how to prepare horse dung/urine, which I will try later. 

The grounding mix is casein/lime/varnish/linseed oil(small amount)/colloidal silica. I'm experimenting to get the optimal penetration without burning the flames, I will probably go a little further than this
