How do I identify a stoneware jug?

Answered by Frank Schwing

Identifying a stoneware jug can be a fascinating endeavor, as these timeless pieces often carry a rich history and craftsmanship. Here are some steps and characteristics to consider when identifying a stoneware jug:

1. Look for a shiny, glass-like surface: Stoneware jugs typically have a lustrous appearance due to the glaze applied during the firing process. This glaze creates a smooth and shiny finish, similar to glass. However, it’s important to note that older stoneware jugs might have a more muted or worn glaze due to age and use.

2. Check for occasional bumps or specks: During the firing process, salt particles were often introduced into the kiln, resulting in small bumps or specks on the surface of the jug. These imperfections can add character and authenticity to the piece.

3. Observe hand-painted decorations: Many stoneware jugs feature simple hand-painted decorations, commonly using cobalt blue ink. These decorations can vary from simple geometric patterns to intricate floral designs. The brushstrokes may appear slightly uneven, indicating that they were handcrafted.

4. Look for decorations beneath the glaze: Unlike modern pottery, where decorations are often painted over the glaze, stoneware jugs typically have their decorations applied beneath the glaze. This means that the designs are protected and less prone to wear or fading over time. Careful examination may reveal subtle variations in color and texture where the decorations meet the glaze.

5. Check for hand-drawn or stenciled numbers and letters: Stoneware jugs often bear markings such as the potter’s signature, maker’s mark, or capacity measurement. These markings can be hand-drawn or stenciled onto the jug before it is fired. The presence of such markings can provide valuable clues about the origin and age of the piece.

6. Research and compare: Once you have identified the characteristics of the stoneware jug, it’s time to research and compare. Look for similar jugs online, visit antique shops, or consult reference books on stoneware pottery. Pay attention to details such as shape, decorations, and markings to find comparable pieces that can help you determine the age, origin, and value of your jug.

Remember, identifying a stoneware jug can be a nuanced process that requires a combination of visual analysis, historical knowledge, and research. It can also be helpful to consult with experts or collectors who specialize in stoneware pottery to gain further insights and expertise.
