Vintage 1930s Mountainside Art Pottery Vase John Kovacs Matte Green Glaze 5.5” New Jersey Studio Ceramic Incised MP Mark

A refined example of early American studio pottery, this vintage vase was produced by Mountainside Art Pottery of New Jersey, a short-lived studio operating from 1929 to 1941. The form reflects the organic, hand-thrown sensibility of early 20th-century American ceramics, with a softly balanced silhouette and subtle surface variation that highlights its handmade character.

The glaze features a matte green base enriched with soft yellow and brown accents, creating a layered, earthy surface with natural variation and depth. The finish emphasizes a quiet, organic aesthetic typical of early studio pottery, where form and glaze work together rather than high gloss or uniformity.

The base is incised with the distinctive “MP–” mark, confirming production by Mountainside Art Pottery. Based on this mark and the known studio output of the period, this piece is attributed to studio work associated with John Kovacs, a maker linked to Mountainside production during its active years. The vase stands approximately 5.5 inches tall and remains in excellent vintage condition with no chips or cracks noted.

Because Mountainside Art Pottery had a relatively short production span, surviving examples in clean, intact condition are increasingly scarce. This piece represents a strong example of early New Jersey studio ceramics and holds appeal for collectors of historic American art pottery and early studio wares.
