Bread-Bakers v112.n004.6

Romertopf has a web site: www.romertopfonline.com. There is a 
"contact us" link at the bottom of the page. I have two of the pans 
and love them for roasting chicken and making vegetable concoctions, 
but I have not used them for baking bread. Williams-Sonoma is a major 
seller of the pans. You should be able to get a response from that, 
too. Good luck!
