Wood Blackening with Tannic Acid

[Bugra]

Hey there ; 
 
Since last login ( several years ago ) too many things changed in MSW. Topics are gone too, I guess. 
 
So here is my first post and attempting to  blackening wood.. 
 
 
1 - 1gr/Tannic Acid can easily dissolve in 35ml Water. So, prepared solution with this ratio. Other liquid is Fe + Vineager. I put down rusted(!) screws in a vineager for a week. But there is a point, don't forget to make a hole on cap. Not much but there will be a gas. This is for preventing pressure. Testing solution on Pear, Boxwood and Mahogany.
 

 
2 - These are first attempts. 
 

 
3 - After multiple applications reason satisfied me. How much application, such blackening deep in to wood. 
 

 
 

Edit : Guess, it's in wrong place. Sorry for that but appreciated if mods can move it to the proper place. 

 

 

Cheers, Bugra.
