I’ve just been wondering as I read about diffusion. I read that the
Etruscan pieces give little evidence of eutectic bonding. “Scanning
Electron Microscope analyses of ancient granulations show however no
difference in alloy between ball, contact point and surface
metal.”(Some Notes On Granulation Article by: Charles Lewton-Brain �
1996) Someone must have attempted, in their search for the
"granulation solution", just plain diffusion without the use of
metallic salts. Presumeably it failed(I don’t read much about the
failed attempts-any sources) Just wondering why. Is it because it
would be difficult to “clamp” the granules to the base? If the whole
piece, granules in place, were encased in clay or plaster(Etruscans
probably had access to some form of this) that expanded more slowly
under heat than the metal could this not create the pressure needed?
Would the problem then be finding a way to place granules while
keeping the contact surfaces necessarily spotless? Please forgive me
if right now my circumstances hinder my being able to experiment on
my own. Soon, with a flame and a hammer my inquisitiveness will yeild
its fruit and I’ll remember to repay my debt to you(though likely
