How to Authenticate Real Antique Glass: More Than Meets the Eye

Verifying the authenticity of antique glass can be a daunting task, especially for the average individual who may not possess the expertise of an expert. While certain indicators can provide useful clues, it’s important to understand that these alone are not foolproof. This article delves into various aspects to help you authenticate antique glass and discern its true value.

Understanding the Nature of Antique Dealers

Antique dealers, for the most part, are not inherently dishonest or crooks. They are simply in the business of making a livelihood by buying low and selling high. It’s an inherent part of the business model that they might value items differently based on market conditions and personal expertise. This is where the challenge lies for the average buyer.

Initial Indicators and Guidelines

Even without the aid of a porcelain and glass expert, there are some basic indicators you can observe:

Weight and Thickness

Antique glass may often be slightly heavier or thicker than modern glass, but this is not an absolute rule. While weight can be a useful indicator, it is not always reliable.

Color Uniformity

Check the uniformity of the color throughout the glass. Antique glass may have slight variations or discolorations, possibly due to the manufacturing process or natural aging. If the glass has uniformity through and through, it might not be as authentic.

Distortions and Bubbles

Antique glass often has visible distortions and tiny bubbles, which are natural imperfections typical of older production techniques. If your piece is completely clear with no visible flaws, it might be a red flag.

Frame or Holder

The frame or holder can also be instructive. Antique items are often paired with old frames that are also of historical significance. If the frame or holder looks modern, it may indicate that the piece is not antique.

Seeking Professional Help

For the most accurate assessment, it’s recommended to consult a porcelain and glass expert. These professionals can provide detailed insights and authenticate the piece with credible evidence.

Experiencing the Market

Another approach is to visit an antique shop that specializes in glass objects. Bring your piece and ask for its value. Many dealers will undervalue the item by 50% to secure a purchase at a lower price. If the dealer says the item is not antique glass and refuses to buy it, it is likely not authentic. However, some shops may also try to buy the item at a discounted price, suggesting it might be real.

Through these methods, you can gain confidence in determining the authenticity of your antique glass. It's crucial to approach the process with skepticism and a willingness to do thorough research and seek expert opinion.
