NEMADJI Pottery Vase ??-Un-Marked

I collected this pottery for many years as I love the swirls of color you see on each piece.Many people do not know the origin of this pottery so I will add a brief History.Nemadji Pottery has been produced at the gateway of Minnesota's Arrowhead Region since 1923.The plant was founded in the City of Moose Lake which is at the crossroads of Minnesota state highway 73 and Interstate-35.Nemadji Tile first graced the floors of many churches and businesses and the homes of America's most wealthy.The less expensive pottery was produced as a tourist item during the great depression.It was sold primarily in the west and in the northwest as "Indian" pottery.The only connection to Minnesota's Ojibway Tribe is the Name,Nemadji which roughly translates as "Lefthand".While never produced by Indians the pottery was promoted as being reminiscent of ancient indian pottery-overtime,it became known as "Indian"Pottery.The pottery was first made using the rich clays taken from the banks of the Nemadji River.The special painting technic used to give it the pottery its unique look was developed in 1929 by Eric Hellman.The Nemadji plant moved to Kettle River in 1972-73.The new owner updated the plant and made significant changes to the pottery.The plant was sold again in 1980.Within one year the new owner closed down the tile making end of the business.Production of Nemadji Pottery ended in the winter of 2001-2002.This is vase that is 3 1/4" tall and is un-marked,so I can not say for sure this is Nemadji.Has all the same charcteristics though.Un-glazed inside.
