Copper
Purity = 999
Image taken with 35mm camera, shutter speed = 1/250th of second in bright sun using 200 film.
Although this copper was completely melted and formed a spheroid very little sublimate formed, except for the small amount of green color close to bead.

Sublimate colors are different due to intense light source, but some green and pinkish-red is noticeable.
The cracks in plaster tablet are due to heat from propane torch.
This bead was created from a metal sample cut from large piece of metal and the propane torch caused to melt and become an ill defined spheroid.
The carved out depression is to help keep the metal in a confined area and not be blown away when the torch flame is applied to the area.
Only the oxidizing portion of the flame is used.

Equal amounts of Copper & Bismuth melted together
Image taken with 35mm camera, shutter speed = 1/250th of second in bright sun using 200 film.
Notice the effects of the low temperature melting Bismuth (yellow sublimate) and how it transports some of the Copper oxides.

The crack in plaster tablet due to intense localized heat from propane torch.
Only the oxidizing portion of the flame is used.

Equal amounts of Copper & Lead melted together
Image taken with 35mm camera, shutter speed = 1/250th of second in bright sun using 200 film.
Because Lead melts at a lower temperature than Copper some Copper (reddish) is carried along with Lead (yellow) to form combined colored sublimates.

Sublimate colors are different due to intense light source
It appears that both Cu & Pb was being absorbed into the plaster during the melt and small Lead & Copper beads were reduced away from direction of flame.
The cracks in plaster tablet is due to intense localized heat from propane torch.
Only the oxidizing portion of the flame is used.
