Verfy small forged copper bowls

Verfy small forged copper bowls

Experimenting with an idea before I make a large bowl.

Scaled up to say, 4"

Scaled up to say, 4" diameter depression those things would be impressive - and really heavy! I like the textures created on the sides by the expansion stresses. Might be fun to work with that, seeing the effect of different initial finishes on the final product.

I'm looking forward to seeing the next stage!

We think alot alike,
The texture on the sides is why I am doing this experiment in miniature.
Every bowl has a different texture on the sides, some are serrated, some checkered, some stippled some straight off the bandsaw. I did not get the full effect I was looking for but believe if I use a 2' round disk 1" tall I will get what I am looking for. Then next go to larger scale, like the 4" you recommend.
PS I did not get the expansion out the sides I was seeking but it was close.

HHMM, now you got me thinking.

spiral lumps

I used to play with lumps into bowls ....thought you might like to see what happens if you push right through .....these were 6x6x2 inch blocks or the end of slabs ...punched through to form the vertebrae of a spiral staircase. punched slabs and blocksspiral lumps: punched slabs and blocks

A few very inspirational pieces on your website. There are a few in the 25 years ago folder that speak to me.
Great work, that staircase vertebrae is larger than I would have guessed by the photo. I am guessing you use a hydraulic press for this work. I used a power hammer for my piece. I will probably just make a hand held die for the larger bowl I do to use with my flat dies.
What I am attempting to accomplish is to get the copper to extrude out the features I created on the sides of the copper, if that makes sense. I in essence want the features on the sides of the bowl to grow.
Not sure its possible but in my mind it should work with a taller piece and more heat.

power hammer

the stairs were made with power hammers....I have some bowls that used opening grain as a feature.....I will try to find some pics.....the more sudden the force the greater the bulge....copper may absorb that force though ....steel is better.
