oxidized lead moulds

[pingu]

guess nelson knows answer to this but know others make as well

went to go and make some leads this morning as got a lovely new 5oz gripper mould from evilbay( yes theres some for you tonight baggie)

but also went to do some plains, got the moulds from the shed and they have somewher/somehow got damp possibly( but everything else dry arround??) and fouund them all comered in white oxidized residue

now i have scrubbed them off and put in oven to dry
now they seem a bit pitted

is there anything i should worry about with them now

going to buy some fine wet and dry to clean better
after dry
also can you do anything to stop this

cheers

dunno what the xperts will recon but we never worried about the odd bit of oxidization or pitting on our old moulds, never cleaned or treated in any way other than to make absolutely sure they were hot and free from moisture b4 pouring.

i'm not sure but i'd suspect that any grease or wax etc to prevent oxidization would cause the same prob as a damp mould if not thoroughly cleaned out b4 pouring, ie- explosion.

how deep is the pitting?? shouldn't be a prob unless it eats a hole through the mould

Hi Dave, the moulds just got damp, before you use make sure they are well
smoked, (sorry if you already know this) black by holding the cavity over a candle, this aids release and seems to help in slowing down white mould.

Could you store them indoors? would solve the problem.
