I have compiled a few interesting and informative facts about Japanese Cloisonne Ware. 
My information is based upon an original Sato Ware Co. 1950's brochure, several 50's vintage vases and the Sato-Shippo web site.

• Sato-Shippo is a company that started manufacturing Cloisonne Ware in 1936 and continues to be in business today.

Some designs continue to be in production:

The new vase has a lot in common with this older model:

• Sellers and buyers, here is a 50's era SATO cloisonne mark. The circle design was part of a seal that originally said Quality Guaranteed and Trade Mark.

• During the 1950's, 1st grade finished Sato pieces were stamped on the bottom, there may be seconds from the same era without marks.

• Transparent Red color is called Pigeon Blood. The 50's pigment is made with GOLD, but it is always RED. Many sellers describe any Cloisonne color as being Pigeon Blood.

• Top and bottom edges of finished SATO pieces were trimmed with silver or (more commonly) nickel silver bands.

• The base of 50's Sato Ware is sheet copper.

• Jade or Apple Green color was not available in the 50's Sato product brochure, but is currently being produced:

• More than 17 Named designs / combinations were available in Sato's 1950's brochure. No wireless designs were offered.
