: Well most of that is correct. The law states that 1/20 of the total
: weight not thickness needs to be gold to be considered GF. The
: gold filling process is not technically a plating process. The
: gold is put on with heat and pressure so it fuses to the base
: metal, usually brass. This process yields a layer that is ~100
: times thicker than the electroplating process. GF is not
: technically a plating process since there is no electrolytic
: process or an autocatalytic process that takes place...it's
: physically fused to the base metal.
: Sometimes gold plating is also labelled as HGP if the plating layer
: is 2.5microns. Normal GP layers are .5. Hope this helps
While on the subject, I've got an old Hamilton that says "rolled gold" on the case. Whats the deal with that?
Also have an old Connie that is gold capped. Curious.
Thanks
