We were trying to prepare a chocolate cake using a Panasonic Microwave. We set the oven to auto mode for cake preparation. There was a time for preheating (180°C) and then asked us to place the cake tin inside which would cook for 35 minutes, but when it was just six minutes after process started, the vessel started to melt.
We first used the vessel provided by Croma which melted and then we tried using the vessel provided by Panasonic for microwave, that also melted.
What was the cause for this and can we eat the cake that was in the melted vessel?
