tannin in metal conservation

[Marcus Mummius]

Salvete,

I am looking for recipes for tannin used for metal conservation (iron).

I am going to experiment with different recipes and analyse the results.

Has anyone got experience with tannins in metal conservation? Can you tell me what recipes you use or are familiar with?

You can contact me at the following adress: jef_pinceel AT hotmail.com

Thanks in advance!

Valete,
Jef
