In addition recovery of calcium in making the 1-2% master alloy is generally less than 90% because of oxidation of the calcium during alloying and pouring despite the inert gas and salt covers. Finally, because of the limited solubility of aluminum in lead, it is not possible to directly alloy the aluminum into the calcium-lead master alloy.
