Janito Posted August 12, 2019 Report Share Posted August 12, 2019 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? Quote Link to comment Share on other sites More sharing options...

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. Quote Link to comment Share on other sites More sharing options...

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. Quote Link to comment Share on other sites More sharing options...
Peter K-G Posted August 13, 2019 Author Report Share Posted August 13, 2019 BTW, Roger's varnish is not that red! Sunlight and cameras aren't telling the real colors, red is pronounced too much. (From his Bass book p. 134) Quote Link to comment Share on other sites More sharing options...

I haven't tested, it would probably be totally transparent like just 2 glass slides, if I dilute it and squeeze them together Quote Link to comment Share on other sites More sharing options...
Peter K-G Posted August 18, 2019 Author Report Share Posted August 18, 2019 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 Quote Link to comment Share on other sites More sharing options...

I don't understand your chart, what is in Y/X? I would thought Hz/Weigth, but as the target should be <360 it seems you were far from target when you did the post. Then I wonder why it is usefull to make measurements and records at his step. 2. How do you know the target values at this step ? I read the old articiles in publications, but most measured values are with finished and old plate, then during making process, as the varnish, bass bar, purfling and edge effects are unknown it seems difficult to predict correctly. 3. "Italian arching" : do you mean Sacconi arching or similar one with some adjustments ? - I noticed you drawn a big C joining the Upper and Lower bout? your purfling looks nice. One can see the maple texture on the white part.

Peter K-G Posted August 8, 2020 Author Report Share Posted August 8, 2020 David & "Cowboy" Thank you for your interest. At the moment I'm busy cooking varnish and making a violin (the fifth in the series of 10 Strad Soils). Hope I can get back soon with some more answers. In the mean time you might want to explore conversarions and debates on the matter about Patrick Kreits' research? What I do is following his work and finding new "evidence" and findings. It's a life time work.. br. Peter Quote Link to comment Share on other sites More sharing options...
