Distinctive Characteristics

What makes cobalt blue glass so special? Here's what to look for:

• Color Depth and Consistency: The intensity and evenness of the blue color are key indicators of quality. Genuine cobalt blue glass exhibits a deep, saturated hue that is consistent throughout the piece. Variations in color can sometimes indicate the use of different manufacturing techniques or the presence of impurities. The color should appear vibrant and uniform when viewed in natural light. We've often found that the deeper the color, the more valuable the piece.
• Transparency and Clarity: High-quality cobalt blue glass typically has excellent transparency, allowing light to pass through and enhancing its visual appeal. Look for glass that is clear and free from significant bubbles, streaks, or imperfections. These characteristics indicate a well-controlled manufacturing process and a high level of craftsmanship. However, it's worth noting that some vintage pieces may have minor imperfections due to the manufacturing processes of the time.
• Weight and Feel: Cobalt blue glass often has a substantial weight and a smooth, polished feel. The weight is a result of the density of the glass and the amount of cobalt oxide used in the manufacturing process. Handle the piece to assess its weight and feel. Genuine cobalt blue glass tends to feel solid and substantial in the hand.
• Manufacturing Techniques: The way a piece was made can tell you a lot about its age. For example, hand-blown glass often has slight variations and imperfections, while machine-made glass tends to be more uniform. Knowing the manufacturing techniques used can help you date and identify the piece.
• Marks and Signatures: Many vintage pieces bear the marks or signatures of their makers. These marks can be found on the base, side, or rim of the piece. These marks can provide valuable clues about the piece's origin, manufacturer, and date. Familiarize yourself with common marks used by different glassmakers to aid in identification.

2. Identifying Vintage Cobalt Blue Glass: Techniques and Tips

Knowing how to spot genuine vintage cobalt blue glass can be a rewarding experience. Here's a detailed guide to help you identify these treasures.

Examining Color and Clarity

Color and clarity are your first line of defense. Remember these points:

• Color Intensity: Authentic cobalt blue glass should have a rich, deep, and consistent blue color. Avoid pieces that appear faded, washed out, or unevenly colored. Examine the glass in various lighting conditions. Natural light often reveals the true depth of the blue color.
• Clarity: Look for glass that is clear and free from significant imperfections, such as bubbles, streaks, or inclusions. While minor imperfections can be acceptable in vintage pieces, excessive flaws may indicate lower quality or a modern reproduction. Inspect the glass for any signs of cloudiness or haziness, which can detract from its value.

Assessing Manufacturing Techniques

The manufacturing process can tell you a lot about the age and authenticity of a piece. Keep these points in mind:

• Hand-Blown vs. Molded Glass: Hand-blown glass often shows slight variations in shape, thickness, and size, as it was created by artisans. Molded glass, produced using molds, tends to be more uniform in shape and size. Examine the piece for any signs of tooling marks, such as pontil marks (left by the rod used to hold the glass during blowing) or mold seams, which can help you determine the manufacturing process.
• Tooling Marks: Examine the surface of the glass for any tooling marks, such as pontil marks (a small circular mark on the base of hand-blown pieces) or the remnants of a mold seam. These marks indicate the manufacturing process used. Pontil marks, in particular, are common in hand-blown glass and can be a sign of authenticity.
• Thickness and Weight: Authentic vintage glass often has a certain heft and thickness. Compare the piece's weight and thickness with those of known vintage examples. However, this is not a definitive test.

Deciphering Marks and Signatures

Marks and signatures are like a signature on a piece of art. Here's how to interpret them:

• Researching Marks: Familiarize yourself with common marks used by glassmakers. Consult books, online resources, and expert guides to identify the manufacturers and the time period associated with each mark. Keep a record of the marks you find.
• Checking for Authenticity: Examine the quality and style of any marks or signatures. Authentic marks should be clear, consistent, and well-executed. Look for signs of tampering or alterations, which could indicate a reproduction. Examine the mark in detail to assess its authenticity and determine its age.
• Cross-Referencing: Always cross-reference the marks with other identifying features, such as the piece's style, color, and manufacturing techniques. This helps confirm your findings and increases the accuracy of your identification.

Utilizing Expert Resources

Sometimes, you need to call in the experts. Here's how:

• Appraisals: Consider having a professional appraisal done by a qualified expert. Appraisers can provide valuable insights into a piece's authenticity, age, and value.
• Online Forums: Engage with online communities dedicated to collecting glass. Share photos and ask questions. Many collectors are very generous with their knowledge.
• Museums: Visit museums that specialize in glass. Study the collections for reference. You can learn a lot from seeing authentic pieces in person.
