Photo reference

2 uploaded photos

Overview

A classic, heavy-walled ceramic mug finished in a deep, high-gloss cobalt blue glaze. It features a traditional C-shaped handle and an unglazed bottom ring typical of commercial kiln firing.

Story

This classic silhouette represents the workhorse of the modern kitchen. Before the explosion of custom travel tumblers, heavy stoneware mugs like this were the canvas for corporate promotions and cozy morning rituals alike.

Maker / Origin

While the maker is unidentified due to the lack of backstamps or maker's marks, this style of slip-cast stoneware was produced in massive quantities by both domestic pottery companies and international manufacturers to supply the promotional and housewares markets.

Condition & Value

The mug appears to be in good vintage condition with a highly reflective glaze. There is some typical light wear on the unglazed foot ring and minor glaze pops or imperfections from manufacturing on the bottom. Excellent condition preserves its utility 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
