How to Tell if Antique Glass is Valuable

Antique glass can be a captivating addition to any collection, but determining its value is not always as straightforward as it may seem. Glassware is an ancient practice, with cultures creating glass pieces over 4,000 years ago, as such the variety in the field is astounding, making the valuation process require a keen eye and vast knowledge of the field – something that our valuers here at Dawsons have in abundance.

What is Antique Glass

In order to understand what may class as “antique” glassware, it is important to clarify that the term “antique” generally refers to any item that is over 100 years old. Whether you're buying or selling, understanding what qualifies glassware as "antique" can significantly influence its value. With that being said, antique glassware comes in the form of many different pieces – most commonly vases, bowls, bottles and dishes.

In addition to the many depictions of glassware, the type of glassmaking process that is used can greatly differ from piece to piece, thus creating a huge variety of sought-after products. Pieces can range from the aurora-like carnival glass popularised in the 1920s, to the smooth, white milk glass of the 16^th century, to the unique hobnail glass design from the late 19^th century – each of them coming with their own personality and beauty.

What impacts Antique Glass value

Age and Rarity – as with all antiques, usually the older a piece is, the more it could fetch at auction. Scarcity is also an important factor, as a rare find would generally be valued higher due to its low availability.

Condition – perhaps the most important factor when valuing glassware, the condition impacts its value as chips, scratches and cracks reduce its desirability. Wear and tear is expected with most antiques however, due to their age, and so even if you think a piece you own may not be worth much, it is always worth getting it valued by a professional.

Manufacturer – renowned makers of glassware oft bring with them a certain assured quality and craftmanship that makes them more desirable and thus valuable. As with most antiques, a brand’s reputation commands a higher asking price – think Lalique or Baccarat. Similarly, if a piece were to be made by an esteemed glassmaker - i.e. Rene Lalique, Dominik Labino - then this would naturally increases its value.

Design - the form glassware takes and the decoration that accompanies this also plays a part upon its valuation. The style of these designs can often help indicate the period it was made in, and give a more accurate estimation to its value. Typically, pieces with more intricate designs, such as etched or cut glass, tend to be more valuable than plain ones, though that is not to say that more simple glassware is not sought after.
