Paper wasps build nests using fibers to form a paper like substance.
Inside, they look like this:
I made some foam and paper sprues
and attached them to the nest fragments with masking tape:
These were packed in loose sand (shake gently while doing this).
Them moltnm aluminum was poured in the sprues.
This is the resulting rough casting:
This is the back, with the sprue still attached>

I was born and raised in Pittsburgh, Pennsylvania. As a child, I played on old coal mine dumps in my neighborhood, which were the remains of mines that fed the J&L iron and steel works. Although I had uncles who worked there, I did not pour iron myself until I managed to get to Herman. Minnesota, for their last pour. Wayne Potratz helped me accomplish my first large scale iron casting,which weighed 50 lbs. It was somewhat difficult to find a place to cast iron, until I took a summer program at Ox-bow, School of the Art Institute of Chicago, under Norwood Viviano and Dan Matheson. I later went to the Indianapolis Art Center for a multiple-furnace iron pour, and did a few “rolly molds” under Kelly Ludeking’s instruction. I have built a small aluminum foundry in my backyard, where I can produce maquettes and other small-scale castings.
