Vance, I think most automotive castings are done this way now, certainly engines, manifolds, and such, and apparently it's a technique which makes moulding for the home foundryman much easier as there are no flasks, matchplates, coring, mulling, ramming up, etc, to be fooled with. Just pack it in sand, poke vents in it, and pour away. But I don't intend to become a home foundryman, and I did call our local bronze foundry, and even with almost 40 years in the casting business he'd never even heard of lost foam! That's why I have to find a source elsewhere. Regards, Harry
