While looking up something else I came across this site.
http://www.solidteknics.comFrom down under a new line of cast iron and carbon steel hollow ware. Sounds interesting to say the least also somewhat expensive but if you figure the years of use maybe not so much.
To quote "SOLIDTEKNICS is built on the premise that there are enough people like us who are tired of the waste and damage of the disposable consumer world, and are willing to think before they buy. To take personal responsibility for their purchasing decisions, and thereby influence corporate and governmental policy by 'voting with their wallet'.
We believe in a more sustainable industry where cookware is not a disposable item, and is not coated with questionable synthetics for a little extra consumer convenience.
We only want SOLID cooking tools that are designed to be the best of their kind in the world, and made with such quality and integrity that they will last for multiple generations and centuries; investing in treasured heirlooms to be passed down with SOLID love of family, friendships, and good, healthy, home-cooked food."
Amazon has some of their line for sale.
