You've probably seen one in a dusty corner of an antique mall. Maybe it was a deep amber or a striking aquamarine. It’s the George Washington glass bottle, or more accurately, the historical portrait flask. These aren't just old trash. They are basically the 19th-century version of a campaign button or a concert t-shirt. But here is the thing: if you find one at a garage sale for ten bucks, it is almost certainly a reproduction.
Genuine 19th-century glass is rare. It feels different.
Collecting these is a rabbit hole. Most people think "old" automatically equals "thousands of dollars." Honestly, that's just not how the market works anymore. A common Washington-Taylor flask might fetch $200, while a rare color variant of a different mold could buy you a small car.
The 1820s Obsession with the First President
Why George Washington? To understand the George Washington glass bottle, you have to look at the American psyche between 1820 and 1870. The country was young. People were obsessed with the Founding Fathers as these mythical, Herculean figures.
When the Marquis de Lafayette returned to America for his farewell tour in 1824, it sparked a massive "spirit of '76" revival. Glassworks like those in Kensington, Philadelphia, and Dyottville realized they could sell more whiskey if the bottle had a face people respected. It was brilliant marketing. You’d finish your spirits and keep the bottle on the mantel.
The most famous of these is the "Washington-Taylor" flask. Zachary Taylor, the hero of the Mexican-American War, was often paired with Washington on the reverse side. It was a way of saying, "This guy is the next Washington."
How to Tell if Yours is Real or a 1970s Fake
The market is flooded with "Bicentennial" glass. Around 1976, companies like Wheaton Glass produced thousands of colorful George Washington bottles. They look old to the untrained eye. They have the iridescent sheen. They have the rough pontil mark on the bottom.
But they aren't "real" in the eyes of a serious numismatist or glass collector.
Real 19th-century glass has "sick glass" or "bloom" sometimes—a cloudy oxidation that happens over a century. More importantly, look at the neck. If the lip is perfectly smooth and machine-tooled, it's likely a modern reproduction. Authentic bottles from the 1840s usually have a "sheared" or "applied" lip. This means a craftsman literally cut the glass with shears while it was molten or added a separate ring of glass to the top by hand.
It's messy. It's imperfect. It’s beautiful.

The Dyottville Factor and Mold Variations
If you want to talk about the George Washington glass bottle, you have to talk about Thomas Dyott. He was a colorful character, to put it mildly. He called himself "Dr. Dyott" and ran the Dyottville Glass Works in Philadelphia.
Dyott was a pioneer of the American factory system. He even created a temperance community for his workers while simultaneously churning out thousands of flasks designed to hold hard liquor. The irony is thick.
- The "GI-70" mold is one you’ll hear experts mention.
- Collectors use the McKearin numbering system. It’s the gold standard.
- If a listing says "McKearin GI-2," they are referring to the specific mold shape and bust style identified by Helen and George McKearin in their seminal 1941 book, American Glass.
Color changes everything. A standard aqua Washington flask is the "entry-level" piece. But find one in "Pike's Peak" green or a true cobalt blue? Now you are talking about serious auction house territory. Norman C. Heckler & Company, one of the premier auctioneers for historical glass, has seen rare flasks go for $40,000 and up.
Most people just have the $15 Wheaton version. And that's okay! They look great in a window. Just don't try to retire on one.
Why the "Pontil Mark" Matters So Much
Turn the bottle over. Do you see a jagged, circular scar on the bottom? That’s the pontil mark.
It happens when the glassblower detaches the bottle from the iron rod (the pontil). In the mid-1800s, they started using "snap cases" which didn't leave that scar. So, a "smooth base" bottle is generally newer than a "pontil scarred" bottle.
However, even this isn't a perfect rule. Some high-end reproductions from the 20th century faked the pontil mark to trick collectors. You have to look at the weight. Old glass is surprisingly light sometimes, but the glass itself feels "greasy" or soft compared to the hard, brittle feel of modern soda-lime glass.
Myths About "Old" Glass Colors
There’s this weird myth that "purple glass is the oldest." Actually, glass turns purple (sun-purpled) because of manganese used as a de-colorizer. When exposed to UV rays over decades, it reacts.
A George Washington glass bottle that is deep amethyst might actually be a clear bottle that sat in a desert for fifty years. Or, worse, someone put it in a food irradiator to "cook" the color into it to make it look more antique. Serious collectors actually hate sun-purpled glass because it alters the original intent of the maker.

Value is in the original state. You want the color the blower intended.
The Zachary Taylor Connection
As mentioned, Taylor is the most common "B-side" to Washington. This reflects the 1848 election. You'll see "The Father of His Country" on one side and "Gen. Taylor Never Surrenders" on the other.
It’s political propaganda you can drink out of.
There are also variants with ships, eagles, and even the "Tree of Life." The variety is staggering. Because these molds were made by hand-cutting into iron blocks, no two mold families are exactly the same. The hair on Washington's head might have three curls in one version and five in another. These "die varieties" are what keep the hobby alive.
The Reality of the Current Market
Is the George Washington glass bottle still a good investment?
Honestly? It's complicated. The "Big Box" collectors—the guys who spent millions in the 90s—are aging out. Younger collectors are more interested in mid-century modern or "weird" 1970s kitsch.
But "High Americana" never truly dies. The top 1% of bottles are still breaking records. The middle market—the $500 to $1,500 range—is a bit softer than it used to be. This is actually great news if you're just starting. You can get a piece of 180-year-old history for the price of a new iPhone.
That iPhone will be e-waste in five years. The bottle will still be there, holding the light.
Real Evidence of Value
In 2021, a "Firefly" colored Washington flask (a vibrant, glowing yellow-green) shattered estimates. It’s all about the "eye appeal." If you have a bottle with a lot of "seed bubbles" (tiny air bubbles trapped in the glass) and a "whittled" texture (where the cold mold caused the glass to ripple), you have a winner.

Texture is everything. You want a bottle that looks like it was made in a workshop, not a clean room.
Actionable Steps for New Collectors
If you've found a bottle and want to know if it's the real deal, don't just Google "old bottle." You'll get a million confusing results. Follow this specific path instead.
1. Check the seams. On a real George Washington glass bottle from the 1840s, the side mold seam should stop before it reaches the very top of the lip. If the seam goes all the way over the rim and down into the mouth, it was made by a machine. Machine-made = 20th century. No exceptions.
2. Evaluate the "Ring." Gently (very gently!) flick the side of the bottle with your fingernail. Lead glass or very old soda glass has a dull "thud" or a very short, high-pitched "tink." Modern glass has a different resonance. This takes practice, but you'll start to hear the difference.
3. Use the McKearin Charts. Go to a library or find a PDF of American Glass by George and Helen McKearin. Look for the "GI" section (Group I: Portrait Flasks). Identify your bottle's specific mold. If your bottle doesn't match a known mold exactly, it is likely a modern commemorative piece.
4. Look for "Wear Ice." Check the highest points of the relief (Washington's cheek or the letters). On a real antique, there should be tiny, microscopic scratches from being set down on tables for 150 years. This is called "base wear" or "shelf wear." If the bottle is perfectly pristine and shiny everywhere, be suspicious.
5. Consult an Expert. Before you list it on eBay for $5,000, send a photo to an auction house like Heckler or American Glass Gallery. They often do free basic evaluations via email. They've seen it all, and they can tell a Wheaton reproduction from a Dyottville original in about two seconds.
The world of historical glass is a mix of chemistry, art, and American ego. Whether you own a $20 shelf-piece or a $20,000 museum artifact, these bottles are a tangible link to a time when glass was precious and a president's face was a symbol of a brand-new world. Stop looking at the front; start looking at the lip and the base. That's where the truth is hidden.
