Is there aproblem with quenching veryhot items in the pot
... Like to know cause I do it all the time....
hi jim, i don't do it anymore. there was a thread recently
concerning this issue recently. spattering of acid solution can
be a problem on your clothes, skin, eyes, coworker and etc.
there was also discussion of the pickle actually entering the
expanded micropores of the metal if the metal is doused hot.
this can make subsequent solderings difficult. i don't know if
this actually changes the surface of the metal like anodizing
does to aluminum or if the acid trapped (or whatever it has
become) is released from the micropores by the subsequent
heating. i have also read that quenching metal too hot can cause
the metal too warp, and if it doesn't warp, certainly it will
cause uneven cooling which causes uneven crystallisation
creating tension in the workpiece.
i'm not sure, but i think you are replying to post where i
talked about the method of heating the 'burnt crud' to clean
behind diamonds. this also i don't do anymore. i have messed up
a few rings this way: retipped prongs melting, fine wire
galleries melting, burning diamonds etc. perhaps it was the
result of my being too bold or careless. in any case, i use what
i believe to be a better, safer solution: 1/2 diluted liquid
plummer or drano in a beaker placed in the sonic.
