For Sale is a Lovely Vase made by The Dugan Glass Company of Indiana, PA. The Vase is in a very desirable Shape. I would call this Shape a "Swollen Form with Raised Lip". The Vase is a Good Size as it stands 6 1/8" tall and is 3 3/4" in diameter. In period catalogs it is indistinctly called Venetian, Pompeian, or Japanese, which all refer to imported fashion crazes of the period.
The Vase Displays the ever Popular Celery Green White Frit Glass with a hand form raised lip. The entire top lip show unevenness and that wonderful hand formed appearance. What makes this an interesting piece is when they executed the Blowing they rolled it in a White Frit Glass Power while the Vase was hot and attached to the Punty Rod. This picked up the Glass pieces and then it was put back in the oven and fired and the white frit became part of the Vase. When you stick your fingers inside the vase you can feel the vertical ribbing. The white frit was fused to these ribs on the outside but you cannot feel the ribs on the outside. This creates somewhat an optical illusion.
The Vase is considered to be in excellent condition as there are no cracks, nicks or dings. The piece is unsigned as is the case with these pieces. This method reminds me a little bit some of the LCT Tiffany Favrile Cypriote Glass examples. This is a quality piece of early American Art Glass. In period catalogs it is indistinctly called Venetian, Pompeian, or Japanese, which all refer to imported fashion crazes of the period.
This piece was made very early, circa 1898-1906. There is documentation that this was a design in the 1898 Catalog of The National Glass Company in which Thomas Dugan was a Partner. The Dugan Glass Company Came into being 1902-1906.
A very nice Ebayer emailed me this information below.
The vase is certainly Dugan and it is from the Japanese line which went into manufacture in 1906. Your last photo shows a hemispherical spot optic on the inside which is only used on the Japanese line pieces.
