doheny, you can get titanium dinnerware from REI and Campmor, it is marketed to high-altitude campers who pare off every last ounce. It has less of a taste than stainles does.
Real pewter is illegal for dinnerware these days because it is made with a high lead content and that leaches out. What is called pewter, isn't really. But there's a lot of "decorator" stuff made out of the ersatz pewter.
