Smelting and using the metal

Art is not always about the making. Sometimes it is in the preparation; the ordering of materials; the acquiring of tools etc. Today has seen me ordering sheet metal and steel rod for elements of a couple of projects; attempting to order some equipment; taking delivery of some recycled silverware; and making a Steampunk Lamp (not yet polished).

During the week I spent four days at an art institute learning the art of recycling scrap silver; forming useable sheets and rods from the smelted metal; using the silver plate and rod to make a few pieces; and learning about some sustainable and non toxic processes and chemicals along the way.

In the following I want to share some photos of the smelting process; and the creation of plate and rod. I will then go on to share a few photos of the pieces I made from some of the silver we smelted. I also took along some old worn silver coins that I also smelted to create some coin-sliver plate that I will use at home. We were taught by a silver-smith Claire Poppi.

Melting  the recycled 925 silver which is mixed with new silver scraps..

©2015 - Lots of heat - took about 5 minutes to melt 60+ grams.

The crucible after the pour. We did 6 smelts and pours.

The coin-silver ingot cooling; and then cleaned (pickled). The coin-silver is probably about 60-80% pure silver.

Making wire - drawing square rod rolled earlier in the mill. I cut off a piece of the square rod for later use in making a twist ring.

Coin ingot after rolling in a hand operated plate rolling mill. All the ingots looked similar to this after rolling down from about 5mm thickness to about 1mm.

A couple of pendants made from recycled silver. I added a piece of pearl shell from home to the highly polished piece. And the second one has been pickled in citric acid but not yet finished.

And my coin-silver straightened and cleaned - ready for use.

A very enjoyable week I learnt a lot. Now I must go and make a roast pumpkin and blue cheese risotto to go with the red wine.
