Here are some pictures from the foundry I’d like to share with you.
That’s how the pans look like after casting. They still need to be seasoned. This we do by rubbing them with vegetable oil and then heating the pans in an oven at high temperature.
This is after the first seasoning, not yet perfect, but getting there. The process will be repeated until the pans are entirely black. Only then they will be released from quality control!
As final step, the pans will be rubbed again with vegetable oil to prevent them from rusting. That’s why our pans are a bit oily when you buy them. Before first use, heat the pans up and let the oil burn away – that will smoke a bit so use your exhaust hood or do this outdoors. Then let the pan cool down and wipe it clean with a paper towel.
To keep the protective seasoning, never ever wash the pan with detergents! If you do so, the process must be repeated.
