The Low-Down on Forging Sterling Silver Metal Clay

Janet Alexander

Can fired sterling silver metal clay take the brunt of a hammer?

Spoon Plank

I made two spoon planks rolling them out eight cards thick, and lightly texturing the handle areas. I fired them per Mitsubishi's instructions in the kiln.

I hammered the first spoon using a steel dapping block, which was too deep to support the metal correctly. I promptly put a hole in it.








With the second spoon, I wanted to use a wood block but didn’t have one the correct size. So, I made one out of a stump of firewood I found laying outside the house.

Firewood

Carved wood

First I traced the bowl area’s outline onto the end of the stump. Then I used a 10mm ball bur and my rotary tool to carve out a shallow area.

I hammered the bowl area with a rounded raising hammer on the carved stump.

After I got it somewhat domed, I annealed the metal.

Using a dapping tool

I carved the hole in the stump deeper, and since my hammer was too big to fit where I needed it, I used a dapping tool and a rawhide mallet to forge the spoon’s end into the stump.
It worked fine so long as I stopped regularly to anneal the metal before pushing it too far.

Success! Fired PMC Sterling can be forged and the spoon is ready for refining and finishing.
