I have two wire tinning solder pots that have not received the proper day-to-day maintenance and now there is solid crud filling all but about ¼ of the crucible.  I have tried chiseling it out and drilling it out.  All I end up with is dull tools, even carbide drills.

Other than buying new solder pots or replacing the crucibles are there any suggestions for removing this super hard stuff?
