The red that is coming out will probably not be a TRUE RED.
Unless they found some method to make it without violating violating any laws.
I like the idea of a removable handle, just not the shape or style.
It my belief that the reason they rust at all the welded spot is this"
Welding cleans the steel. Really clean. Clean steel starts to flash rust immediately. Porcelain coating doesn't stop what is going on under it. Certain climates and the way they are stored increses the rate at which the rust forms. Its only a matter of time.. Ashes to Ashes as they say..
Enjoy them and rescue any of the oldies whenever you can.
