Electric melting oven + Crucible blowout. Anyone tried the same?

Hey guys! The week havent been good to me so far!

Had an incident where I obviously have pushed my graphite crucible a bit too much… 23 castings… I think I dumped my quite large sprue buttom down in the crucible a bit to hard when I dumped in the silver and it broke off the buttom. Dident notice before everything was melted. Nevertheless i had to turn it upside down with molten metal, safe to say i had sweaty palms!

However got most of it out, hoever some of the metal i couldent get out… And now cooled down… Seems pretty stuck… The theromostate seem to be working fine… Bit clueless how to proceed…

Hi,

interesting issue.

what brand is your electric furnace?, crucible?
what company did you purchase it from?

perhaps you can call their technical support and ask for assistant there as well.

Brand is Forno Elettrico - Italy! Bought from a Danish Jewelry retailer !
Crucible is from tiger Gmbh

Cant complain on any of the products. Been using them for two years now… Just my own fault i would assume being to rough on the crucible!

Spoke with my retailer, and will drive down with the machine tomorrow to take a look at it together!

However the silver is pretty good melted together with the ceramic inlay material, not sure how i will get it off! And i dont think that i would be a good idea having a puddle of molten silver in my melting oven floating around at the bottom every time i make a melt :3

Might need to order spare parts from italy i assume, however right now the delay in production is just a headache, hehe!

hi there,

good luck!

good to know about the crucibles needing care not breaking!

i wonder if they get “old” and have a recommended life expectancy?
