This is a folk etymology. No scholarly dictionary lists "pygg" as a kind of clay. You can only find this "pygg - piggy bank" story in pop-culture books of false etymologies. I am alarmed to see this here, and in the Piggy bank article. Check Chambers, Oxford, Webster -- no proper dictionary mentions this cock-and-bull story of "pygg" clay. 31.52.81.111 (talk) 12:34, 13 January 2013 (UTC)
- "Pygg" is just a 15th-century spelling of "pig". Merged to earthenware. — kwami (talk) 00:25, 17 January 2013 (UTC)

- Not a reliable source. It seems that meaning was made up in the '60s (note that that isn't a reliable source either, but it at least gives its sources), which is backed up by some perfunctory searching on Scholar. Kolbasz (talk) 21:45, 28 March 2016 (UTC)
