[can-talk] Tannic Acid

Hi All

I went to the WA Museum metal conservation workshop last week (it was
excellent) but can't seem to find in the notes about diluting tannic acid
for rust conversion/prevention. I get the feeling that it was soluble in
water, methylated spirits but not petroleum based products like white
spirits. Can anyone out there confirm that for me?

 

I am also looking for the 'recipe' for its dilution. (how many gms/teaspoons
per ml/cups of fluid)

I would prefer not to dilute it in water given that I am trying to prevent
water based rust. J

 

thanks

John
