Cologne pots
Origin of Cologne stoneware pots
The name doesn't literally refer to the city of Cologne, but in the Netherlands, it's used for German stoneware from production areas like Westerwald, Siegburg, Raeren, and Frechen. Westerwald, in particular, grew into an important center for stoneware intended for the Dutch market in the 18th and 19th centuries.
How to recognize Cologne stoneware pots?
Material
- Grey stoneware
- Hard and high-fired
- Exceptionally durable
Salt glaze
Cologne stoneware pots often have a slightly glossy surface due to the use of salt glaze. During the firing process, salt was added to the kiln, making the pottery watertight and suitable for storing food and liquids.
Cobalt blue decoration
Early examples from around 1800–1860 often feature cobalt blue decorations. Think of stylized plants, animals, or simple ornaments, which today are an important identifying feature for collectors.
Functional forms
- Anchovy pots
- Mustard pots
- Storage jars

Usage in the Netherlands
In the Netherlands, Cologne stoneware pots were used for storing fish and anchovies, mustard, preserves, butter, margarine, and spirits. Traders from Westerwald themselves traveled to the Netherlands, which led to these pots becoming widely distributed here and a familiar part of daily use.
