What am I doing wrong

Ok as you can see in the pic below on the lower portion I had a nice wax. The whole thing looked like this, I went to work came back home and as you can see the upper portion turned into a goopy mess. I took the temp of the was and it was at 123C.... is the heat my issue? What am I doing wrong and what can I do to fix the goopy mess?

123C yes heat is the issue. Try 120f next time

How do I fix it?

turning the heat down...

Just a lil overdone! lol Twitch suggest never over 150F. So no more then 66C.

You may have reached Perma Goo status, if temps went too high, there is a point of no return and it will not re-solidify.
