What Is Antique Glassware?

What Is Antique Glassware

Antique glassware is practical and decorative dishes and art pieces created in the late 1800s. You can find different types available on the market, including bowls, vases, glasses, and plates.

Items of various designs and patterns produced from the late 19th to the mid 20th century were the pinnacle of glassmaking, making them collectible. Nowadays, you can consider every piece of glassware more than a century old an antique.

 

Ways to Identify Antique Glassware

Antique glass is a group of different glassware types manufactured over centuries. You can recognize them thanks to a few crucial features.

Crystal or antique glass

The crucial step is determining whether you look at a crystal item or antique glass. The best way to differentiate them is by gently tapping the piece since the crystal sounds like a bell. It has sharp edges and produces a prism effect.

On the other hand, antique glass is heavier, and you can notice patina, bubbles, delicate irregularities, and a pontil mark on the bottom.

Antique glass markings

You should always look for a circular pontil mark on the bottom of blown glassware older than 100 years. Other identification signs include:

  • Logo
  • Signature
  • Typical symbol
  • Trademark

Remember that glassware with a bottle cap manufactured from the 1800s to 1900s had the same numbers on the bottle and stopper.

Finally, you can recognize pieces made in the same mold thanks to similar imperfections and lines. Be aware that these markings can fade over time, and you need a magnifying glass to recognize them.

Pattern

Since the oldest pieces typically come without a mark, you can distinguish them thanks to the characteristic pattern. Each manufacturer created its own glassware look, and it is possible to recognize it after fast surfing the net.

Color

Color

Antique glassware comes in various colors, but the most popular are:

  • Red Cranberry glassware, created by adding gold oxide to the molten glass
  • Deep blue Cobalt glassware, which production includes cobalt salts
  • Pale green Jadeite glassware that got its unique shade thanks to added uranium
  • Golden Amber glassware appeared after adding sulfur to the glass

When antique glassware is without a signature or mark, you can identify its age thanks to atypical color or bi-color.

Imperfections

There are a few flaws that can confirm you look at antique glassware. The most common are:

Bubbles – Most antique glassware contains tiny bubbles inside the glass due to the production process.

Chips – This flaw type is often smooth and deep, and you can feel it under your fingers. Chips will probably decrease the glassware value but are the sure sign you have an antique piece.

Cracks – It can be challenging to find them, particularly if you have glassware with a complicated pattern. The best option is to take it to the sunlight and check for delicate cracks. Be aware that these imperfections always drastically reduce the price.

Flaking – This flaw type occurs on the antique glassware rim. Luckily, this tiny, thin, and flat piece of glass won’t affect the piece value.

Nicks – Sometimes, you can notice missing pinhead-sized pieces on antique glassware. They are not considered glass damage and won’t affect the price.

Rough spots – You can feel the rough spots under your finger while running along the piece’s rim or base. They will affect the price, depending on damage levels.

Scratches – These imperfections are always indicators of age and regular use. You can typically notice them at the antique piece bottom going in all directions.

Straw marks – Antique glassware always had straw marks on the bottom. These irregularities appeared during glass drying on the straw and were a sure sign you have an original piece.

Feeling

Believe it or not, antique and new glass never feel the same way. They are different in weight, clarity, and color. Old brilliant-cut glass is sharp, while the pressed one is smooth and always has a thin raised line showing you where the mold halves were assembled.
