I was more thinking along the lines of people posting pictures of their own grounds 

 

but I'm happy to share what this is. 

This is:

 

-UV

-nitrite applied along with white vinegar

- glue size to the top

- whiskey, egg white cambium and saffron tincture 

70hr cook lean colophony varnish. About 55%resin to 45% oil. Burnished with glass power until it’s all sealed.

This photo was taken the last time I stripped this instrument this ground was applied about 3 years ago, I’m pleased with the lightfastness of the yellow.

Very very nice

Thank you guys. It is my latest concoct strongly inspired by Brandmair Greiner  and Padding.

The layers are horse shit, protein, and a very light ground layer of an oxidized varnish containing 80% resin/20% linseed oil. This lean varnish seems to have a positive stiffness/weight effect if there is only a mild penetration.

What do you call protein? Caisean?

Can you show a photo of a larger area?

Unfortunately I varnished this piece already. But here is another sample - it appears more yellow and cooler because of almost no uv tanning of the wood.

Amazing how different people can read Brandmair Greiner and come up with completely different substances to match the findings.  

I like when someone starts a thread on this subject matter.

Here's mine from a few years ago,  resting on laurels.. translation.. too lazy to do a new version.  :D

Everything looks good on curly maple,  you should all post your ground on spruce.

... if the lighting is right.  Directional light in a dark room looks totally  different from outdoor bright overcast sky lighting.

And then there's the issue of a single photograph not being able to differentiate between burned flames and a high-contrast, perfect chatoyance sample.
