Making a Mokume Ring Part 2

Still red-hot ingots of Platinum Enhanced Silver and 14K Palladium White Gold after annealing
These are the still red-hot ingots of Platinum-Enhanced Silver and 14k Palladium White Gold. They were just annealed to relieve the stress created by cold-rolling them.
Continued Rolling of the ingots create strips
After annealing the metal rods, they are again pickled, surfaced with a scotch-brite wheel and cleaned in the ultrasonic before being rolled through the flat rollers on the rolling mill to create a strip
Rolling the Strips of Platinum-Enhanced Silver and 14k Palladium White Gold
The sheet is rolled progressively thinner and thinner until it reaches the correct size for cutting into the pieces that will make up the billet stack
The strips are cut into pieces for the billet stack
The strips are cleaned, annealed again, cleaned, pickled, scrubbed with a scotch-brite pad and then cut into pieces for the billet stack
The strips of metal prepared for the Mokume Billet
The many pieces of strip that were cut to the same size have been cleaned and are ready to stack in the clamping jig. The jig is made from 1" square steel and clamped together with grade 8 bolts and nuts. The inside of the clamp, where the stack of mokume billet will touch the steel, has been coated in yellow ochre to prevent the fired mokume billet from sticking to the steel.
Arranging the Strips of metal onto the Mokume Billet Clamp
The pieces of Platinum enhanced silver and 14K palladium white gold are carefully stacked on the clamp using tweezers to keep them clean, as they have been washed and rinsed many times to ensure that there is no dirt or skin oils on them. They alternate: 1 strip Platinum-Enchanced Silver, then 1 strip 14K Palladium White Gold, then 1 strip Platinum-Enhanced Silver, etc..
The unfired Mokume Billet stack in the clamp
Then the stack clamped in the jig and the bolts tightened to create extreme pressure during firing
Wrapping the Billet and Clamp in Stainless Steel foil with Charcoal
The jig with the mokume billet stack is then wrapped in stainless steel and packed with charcoal. The charcoal will create a reducing atmosphere to prevent oxides from forming when the whole package is heated in the kiln
