Yes the heating element stay red until you let the oven open, I don't know why it turn black is it still hot?
(See my reply#410 and your reply#424)
Sub, sorry that I go back to the subject so late. Unfortunately I had not much time for pizzas lately.
As I said before, the "safety" thermostat has been removed in my oven and I only have a aluminium reflector behind the heating element. I still use the method with a small fan and that way the oven does not switch off, even after 30 minutes. The control lamp is on all the time.
When I leave the oven ON, without a pizza in it, the heating element is red hot glowing all the time and the temperature goes up to around 500* C. That way I can also clean the stone nicely. Even when I open the lid shortly to check the temp, the element keeps glowing after closing the lid.
However when I preheat for baking a pizza (and see the element glowing red), as soon a I put the pizza in it and close the lid, the element apparently extinguishes and turns black in colour and stays so. I don't understand this because the control lamp is ON all the time, so the thermostat does not switch off.
Do you have any idea why this is happening ?
