3. Keep the melted lead in the lead pot clean at all times.
4. Always completely fill each mould at one pouring.
5. Dust moulds well with Ambu mould compound before pouring.
6. When castings “shrink” and crack, add pure lead to that in the pot until the trouble is remedied.
7. Be sure melted lead is of proper temperature, by pine stick test, before starting to pour.
8. Remove castings as soon as they set, to prevent the mould from becoming too hot.
9. A perfect casting, that breaks when taken out of the mould, has probably not been allowed sufficient time to “set” or cool properly.
10. Never use a hammer on the surface of the mould. If a casting should stick, pry it out.
