Some copper will be available for those who do not wish to spend money on supplies. Keep in mind however that silver is a little easier to solder. Students who do want to work in silver should bring the following:
 

3” 6mm outside diameter sterling tubing
3” 2mm outside diameter sterling tubing
2 x 4” 24 ga. sterling sheet
3” 20 ga. sterling wire
3” 4mm x 20 ga. flat (rectangular) sterling wire

Everyone should bring a notebook
