Overview

This is a bulbous, hand-finished ceramic planter featuring a rich amber-brown body crowned with a frothy, cream-and-gold drip glaze around the rim. The base shows firing stilt marks and a stamped mold or style number ('7-dU' or similar upside-down), characteristic of mid-century American commercial art potteries.

Story

Ohio river valley potters in the 1930s mastered the art of controlled glaze runs to create unique decorative ware at affordable prices. The frothy rim foam effect occurred naturally as heavy lead-alkali glazes reacted to intense kiln heat.

Maker / Origin

During the early-to-mid 20th century, companies like McCoy, Brush-McCoy, and Hull transformed Zanesville, Ohio into the pottery capital of America. They specialized in utility and decorative wares, using local clay deposits and innovative glaze formulas that made every mass-produced piece feel individually handcrafted.

Condition & Value

The exterior glaze exhibits good gloss and vibrant coloration. Internal mineral staining and minor glaze crazing are visible inside the bowl from prior floral or soil use. Condition is typical for vintage pottery and does not significantly impair display value.

Market Analysis

Comparable demand stays strongest where maker, originality, and venue confidence line up. Broader examples still trade, but the range tightens quickly when provenance, condition, or selling lane fit is missing.

Value Drivers

  • Strong maker attribution with credible period details
  • Better-than-average condition for the category
  • Broader demand rises when presentation and finish feel intact

Concerns

  • Decorative-only demand limits the ceiling
  • Surface wear or missing provenance can compress the range fast
  • Regional sale lanes often underperform specialist venues
