[meteorite-list] weird rock - meteor wrong

[Mr EMan]

Yes I do or in the local dialect "yeppers".  Silicate slag (a glass with also with bands of ceramic/clay) a bi-product of iron smelting which has been produced and disposed of-- all over Pennsylvania for at least 240 years.  It was a popular automotive and rail road bed filler.

This was tapped off the furnace onto a floor allowed to cool them broken up by workers to be hauled off.  This is (ore + flux-iron-CO2)= (silicate glass+ clay).
