Damascus,

I note that Antimony Chloride is listed as an optional component of your "Slakum Formula" to darken wood & if I remember correctly I have seen this in other "Slakum" Formulas in the form of "butter of antimony".

Can you elaborate on the impact Antimony has on darkening light wood. How much does it darken it & what is the color imparted?

The reason I ask is that I've found some of the lighter colored wood difficult to stain dark enough & get the "correct" color & especially when viewing the finished wood at different angles & in strong light.

Just wondering what the possibilities are & I'm assuming that Antimony had a definite purpose or it wouldn't have been used.
