Waiting on the chemical coated blackened brass barrells

I am very interested in this blackening process !

Have posted same question on a number of threads with no result !

Does anyone know what is involved here
Is there any size change as a result

Cheers

I'll contact the gentleman doing this and see if he wants to share the process here.

Strictly UK only .... sorry !...
