Mystery liquid from Koen Padding's workshop

[Helen M]

As part of my project to produce a book of Koen Padding's varnish expertise, I have been helping the family to sell the contents of his workshop.  Amongst the varnish materials was this container.  Its contents look like this on maple.
I can possibly explain the first two ingredients.  "Cremonese" could be the dried bark of Cortex Frangulae, (Rhamnus Frangula, Alder Buckthorn) which yields a strong yellow dye in water; Koen stored this in a plastic container labelled "Cremonese".  He also had a packet of cola nuts, the "Cola Noten".  What KGN or KQN is I have no idea.
What this mixture might be for is unclear.  My best guess is as the colour component of a lake, though in that case I don't understand why Koen would have bottled it separately rather than finishing the procedure.
If anyone has any suggestions, or can suggest what KGN is, please respond!
Incidentally, I still have some varnish ingredients for sale, principally sandarac, fused sandarac, aluminium hydroxide and Magister siccative.  If anyone is interested, I can provide a full list and prices.

Note to moderator: I'm sorry, I may be dumb, but I can't find a way of uploading images, and this post is useless without.  Please can you help?

Thanks, Helen

Helen,

KGN may be in reference to the source of the materials.  There is a pharmaceutical company by that name.

Helen, its unclear from your description whether the KGN or KQN you refer to in your post is the whole container of  (liquid?)  .What is actually labelled KGN or KQN?

Its the sort of personal way i often label my own solutions when experiementing and no-one but me would know what they really were.  But if i was labelling something for example KQN it could  refer to something like a solution of Potassium Quercitron.( Kalium (refering to potassium sulphate or alum) mixed with Quercitron(the yellow dye from various plant materials such as buckthorn). Your photos if i could see them may be helpful. Or it may simply be a pharmaceutical company like Joe suggests.

KOH could look like KQN or KGN in someone's handwriting?

[chungviolins]

Could it be his varnish?

 

If so,I'm interested.

fc,

It could be KOH...Quercitron + KOH yields flavine....
