I have used beeswax for years to flux and recently tried Marvelux. I think I am disappointed. With beeswax I always got a clean looking pot after a lot of smoke followed by a minute of flame. There was a residual smell which wasn't so bad.
When I tried Marvelux I got little smoke but a alot of black glass/crud on top and on sides of furnace. After two hours of this I went back to nature's flux. Did I do something wrong?
What has been your experience with Marvelux? Any suggestions on how to use it?
Thanks in advance...
