Origins Of The Term "PIG"

[astronuke]

My shift partner was going through an NRRPT computer practice test and found an interesting question about the term "pig".  In the answer, the exam bank claims that the origin of this nuclear term is Celtic and "not related to an animal."  I thought I'd check with some of the nuclear historians here at Nukeworker to see if anyone knew the details.

It comes from smelting.  Ever heard of "Pig Iron"?  A pig is simply a chunk of metal.
A simple google search turned this up:

"pig-iron" (This is a mere play upon the word sow. When iron is melted it runs off into a channel called a sow, the lateral branches of which are called the pigs; here the iron cools, and is called pig-iron.)

Somebody would have to be possessed by demon radiological spirits to use pig iron for source storage.  But then I have seen it done (and a mighty stupid idea that was).  Maybe the term derives from source pigs being a "pig" to move.

Melissa is correct. A pig is any chunk of metal and I believe that the origin has nothing to do with an animal, as astronuke has suggested. Whether it is Celtic or not, I don't know.

seems to me that a pig can be constructed out of any metal, as i seem to remember a few stainless models that radiographers utilized for their sources.... maybe it wuz well waxed pig iron though.

maybe the celts were the 1st to stick it in a pig, hence the reference...

from encarta on-line dictionary.... all of the previous definitions plus this tracer...


[Assumed Old English picga . Originally in the sense “young pig.”]

probably where they got the celt reference.... wonder iffen that's pronounced pigahh or pigay.  maybe it was a happy pig.

in metal casting, the actual "pig" looked like a pig without its head. sprues vents and risers used in sandcasting of metals gave the look of a large pig with four legs-vents risers and sprues.  old block cuts of the "secret arts" show pigs of metal laying about the smelter ready to be send from the foundry to the forge.

Okay, so the celtics squashed their pigs with big chunks of metal???

Take it from an old foundry worker from the 'Burg.  Melissa's explaination is the correct one.  Heats of metal (any metal) from a furnace (in the not so distant past) were poured into channels of sand or clay dug into the ground.  The result looked like a sow with her piglets (ingots) attached at the sides.
