WAKAYAMA Japanese Pottery Company - Obscure antique purveyor of blanks & other pieces

This is for ho2cultcha, from a discussion between his collection of Japanese Awaji pottery pieces and my collection of Wakayama pottery pieces and it's marks.

These are glazed green pieces with a mustard yellow base, and worn silver deposit decorations. The red pieces are much rarer, and there was chocolate brown and cobalt blue items with silver motifs also produced. My reference books also show some painted motifs on a rough yellow background they also made.

Another part of their business was to make blanks for the top ceramic artists of the time, 1900, which they decorated and marked with their Japanese Kanji script names. They also produced porcelain blanks with the same molds, I have found pieces such as these, decorated differently the porcelain signed Royal Nikishi, Nippon.
