How To Identify Your Antique Stoneware Crocks

To determine the worth of stoneware crocks, you need to identify when or where it was made. Rarity and the manufacturer are also vital elements in figuring out antique crock values.

Determining the age of antique stoneware

Understanding when a crock was made is a significant factor in determining its worth; here’s how stoneware crocks developed throughout history.

The 1700s: Before the revolutionary war, Americans used to import stoneware crocks, but after the war in the early 1700s, American potters began manufacturing their stoneware crocks. The crocks made during this era were simple and featured hand paints. Most of these designs have foreign alphabet characters. Also, the interior of the crocks made during this era has cobalt blue salt glazing effects.

During the late 1700s, numerous English potters moved to America, and this shift enabled more American potters to produce high-quality Stoneware crocks. Unfortunately, American potters copied the English potters and omitted the fact that the designs were English-made. Newer designs were coated in their interiors using a brown finish known as Albany Slip.

On the other hand, if a Stoneware crock was manufactured in Europe in the 1700s, it has the symbol of an anchor.

The 1800s: During this time, American potters had immensely improved, and their designs proved it. In the 1800s, the most valuable Stoneware crocks were salt glazed crocks made of Kaolin clay. These crock designs were trendy until the middle of the 19th century where new designs were made to meet the consumers’ needs.

German and English designs during this era have a crown or shield logo. Also, it’s important to note that if a piece was constructed after 1891, it has the name of its country of origin. Whereas, if a stoneware crock was made after 1914, it bears the initials “Made in,” then the country’s name where it was manufactured.

The 1900s: By the early 1900s, a lot of companies that were manufacturing Stoneware crocks emerged, and these vessels were a staple piece in almost every home! At the time, most designs had paintings of mythical creatures or human body parts such as arms and hands or clutching arrows or swords.

After spotting these symbols, you’ll see the name of the company that manufactured the crock and the country it was made.

Factors to Determine A crock’s value

Determining the value of a Stoneware crock is highly beneficial. Once you have identified the different types of antique crocks, you need to understand their value. The value of an antique crock depends on various factors that we’ll explain at an in-depth level.

Note: Some factors are weighty compared to others. Therefore, influencing the value of a stoneware crock.

1. Clay Color

The clay color of a Stoneware antique is crucial in determining the value of a Crock. Also, it plays a pivotal role in identifying the maker. For instance, the famous Robinson Ransbottom Blue Crown primarily focused on manufacturing Crocks from yellow clay.

On the flip side, a company like Weller made its Crocks using white clay. If a company was well-known to manufacture high-quality Crocks back in the day, you’d be able to identify it using the clay color, eventually determining its value.

2. Crock Design

The design of a crock significantly determines the value of the vessel. For instance, some of the most intricate designs were cobalt blue. Regardless, you need to be careful before investing in an antique crock.

If the crock has a stunning and delicate design, it is worth adding to your collection since you can sell it for a high price.

In contrast, if a crock design is basic and the decorations were added after the vessel underwent firing, then the crock is not worth it! Its value is potentially low.

Perhaps you might be wondering how one can tell if a crock’s design was added before or after the firing process. Well, it’s pretty simple. If the cobalt blue decorations are adorned below the glaze, they were added before the crock underwent the firing process.

On the flip side, if the decorations are added above the glaze, they were added after the firing process, making them less valuable than their counterparts.

3. Manufacturer

Just like other products, various manufacturers are highly rated compared to their peers. The same would apply to Stoneware crocks, mainly if the maker produced crocks that were loved at the time. You can conduct your research about Crock makers to determine if your vessel is valuable.

4. Crock Size

The size of a crock determines its value. Larger crocks are rare to find than smaller crocks, making them more valuable.

5. Manufacturer’s Mark

Without a doubt, a maker’s mark is one of the most influential logos of a crock. It can also play a role in dictating the value of a crock. If the maker was famous, the vessel would increase in value. Also, if the company behind the logo was renowned, the crock is valuable as well.

6. The condition of the crock

If the crock looks as good as new even though it has been around for a century, then it’s valuable compared to a crock in bad condition.

Regardless, it’s important to note that surface crazing or hairline cracks don’t necessarily mean that the crock is in poor condition. On the contrary, it gives the crock an authentic feel, attracting more collectors.
