This large Merrimac vase stands a tall 11.5" high by 3.5" in diameter at the rim, and 5.5" in diameter at its widest. According to Kovel's, Merrimac Pottery Company was founded by Thomas Nickerson in Newburyport, Massachusetts, in 1902. The company made art pottery, garden pottery, and reproductions of Roman pottery. The pottery burned to the ground in 1908. This vase has a full-bodied and pleasing form. It is glazed in a magnificent, organic matte green glaze, loaded with character and finished to a satin matte sheen. This vase is unmarked to my eye, but guaranteed to be vintage Merrimac Pottery. Close up photos of the bottom show lots of green glaze, which likely covered the base and was ground back in the heavy spots to allow the vase to sit properly. This more than 100 year-old pot is in excellent condition, with a very good restoration to a simple short and tight line at the rim, which present quite handsomely. This Merrimac vessel, in an awesome broken matte green glaze, makes a wonderfully organic Arts & Crafts presentation!
