While lying in the bath the other night, I was mulling over the "like shelling peas" expression (once you've scrubbed your pits and played with your rubber duck for a few minutes, there's not a lot left to do in a bath situation, is there?), and I came to the conclusion that it is an absurdity.

Patterns were sent to several metalcasting facilities for shelling. Pattern removal, firing and properties analyses were done at Missouri Univ.

Due to the weaker green strength of the water-based shell system compared with its predecessor, a number of minor wax assembly and shelling method changes have been necessary to enable all the blade geometries made at the foundry to be manufactured successfully.

An example of this would be a part with a cylindrical core to be formed by the shelling process.
