The shock came the first joy. I showed my new achievement INA proud. When she asked me for the special containers for this, was I quite amazed. I thought always pot was pot. But no, There is extra special for induction fields!
INA had a solution for me fortunately directly. There are stainless steel plates from the Company de buyer in different sizes, which are placed on the induction plate. Wonderful, now I can continue to use my lovely copper pots.
