Instead of plunging you down a rabbit hole of internet links - the distractions of the pursuit overwhelming any prolonged concentration on a single discovery - I'd like to recommend a number of books that provide insight into folk pottery and the resurrection thereof during the second half of the 20th century. These are some of the classics; you can find your own way from there.
