The iron sands usually contain sea coal, a finely ground coal which keeps the sand from adhering to the casting by generating a gas film when in contact with hot metal. For foundries using sea coal in all their sands, the mixture runs about 5% coal dust. Gilsonite serves the same purpose, in that it produces gasses to prevent sand sticking or ...
Introduced in 1994, the now discontinued Ping Zing 2 irons succeeded Karsten Manufacturing's Ping Zing series.
