Aluminum Lost Foam Pour

Me and a long-time friend pour 319 aluminum in the research foundry that I work in. It was his first time to work with molten metal. He is on the pouring end of the crucible cradle and I am supporting it on the other end.

Where is fire?

Where is smoke?

It seems to be not  "Lost Foam Method"

The combustion productions from the foam are there, but the reaction is not as violent as sometimes observed. There are a few reasons for this:

1. The permeability of this green sand is sufficient enough to allow much of the gas to escape without a volcano effect.

2. The cope and drag don't fit together perfectly and so some gas can escape along the parting line.

If this were a steel pour in our foundry, the reaction would be more volcano like.

nice to see it doesn't glow in reality.

@MetPhD Thanks for your explanation ;)

It will be very interesting to see results of that casting.

How using of green sand influences on casting quality?
