When I first started working with metal, everything I made was flat... after awhile I started to realize that metal could also be dimensional. One of the most intriguing and challenging forms for me was anticlastic forming. The best part was getting to buy new tools and getting to use words like 'sinusoidal stake' and even making some of my own hammers.
It was a pretty big learning curve (no pun intended) but I couldn't stop doing it. You can see some earlier photos from the 'Ring-A-Day' series on flickr. Forming it, of course was never enough, so I had to start enameling the forms as well. That was also challenging because I use a torch to fire my enamels and it takes some thinking about how to fire both sides of a spiral shape with a torch. For me, experimenting is one of the most fun things to do, so I was up for the challenge. I like using transparent enamels with Carefree Lustres©.
