Potassium metal from K2CO3 + charcoal

I repeated an experiment done years ago, but now used a stainless steel vessel.
Still unable to capture the K vapors (this requires Ar gas as answers to earlier topics on the same subject by me), but I noted now that the SS vessel just melted on the burner side. The inside of the furnace was 1470 C so the burner side even hotter.
Now I want to find out how to capture the metal. As Nighthawkinlight shows :

he has the same problem capturing the Na / K metals.
