The discovery of the oldest known glass bottle provides a remarkable window into the early origins of glassmaking.
This ancient artifact was unearthed by archaeologists in 1925 during excavations of the ancient city of Uruk, one of the earliest urban settlements in Mesopotamia.
Uruk was a thriving city-state around 3,700 BC, which makes the glass bottle one of the earliest examples of glass production yet identified.
The bottle itself is small—less than 5 inches tall—with thick uneven walls indicating it was free-blown by an early artisan just learning the new craft of glass forming.
Analysis shows the glass contains high levels of silica, lime, and alkali, revealing the basic recipe used over 5,000 years ago. Traces of wine residues confirm it once held a precious liquid.
Of course, we can only speculate about the original owner of this priceless relic.
Perhaps it belonged to a royal resident of Uruk, or a merchant trading goods between Mesopotamian cities.
The sophistication of this early glass technology hints that glassmaking expertise was already spreading between diverse regions at that time.
Whatever its origins, this fragile vessel provides a tangible connection to the earliest origins of glass itself.
The ancient Phoenicians truly revolutionized glass production through the invention of glassblowing.
Though glass vessels had been produced for thousands of years before, early manufacturing methods were laborious and resulted in crude, uneven products.
Glassblowing Changed everything.
Sometime around 50 BC, Syro-Phoenician artisans made a remarkable breakthrough.
Rather than casting glass into molds, they began gathering molten glass on the end of iron blowpipes and inflating it with their breath.
The flexibility of this process allowed skilled workers to slowly expand the glass into thin, lightweight, and delicately shaped bottles and vials.
Early blown glass from Phoenicia shows ripples and tool marks bearing witness to this new technology.
The uneven surfaces reflect the hand-worked character of the first luxury glassware created this way.
Despite the crudeness, Phoenician blown glass represented a huge leap forward. For the first time, artisans could produce finely worked glass on a larger scale.
Once perfected, glassblowing spread rapidly across the Mediterranean.
Phoenician merchants introduced the technique in major port cities, where local artisans added their own innovations.
Within a few centuries, glassblowing had transformed glass from a rare curiosity into an integral part of daily life across the Roman world.
The Phoenicians' ingenious contribution spawned two thousand years of glass craftsmanship that continues today.
The practice of collecting bottled urine may seem bizarre today, but it made perfect sense in the medical context of 17th-century Europe.
During this period, uroscopy - the study of urine for medical analysis—was a standard diagnostic technique.
Physicians and healers closely examined a patient's urine color, consistency, and even taste to assess humoral balance and identify illnesses.
Given urine's perceived therapeutic and diagnostic value, it's no surprise elite individuals started amassing specimens for study.
Displaying impressive "pissoteques" full of urine samples became a way for physicians to flaunt their medical knowledge. The ornate glass bottles kept harmful air from corrupting the contents' vital essences.
Fascinatingly, aged urine was considered most potent, as fermentation was thought to distill the healing spiritual qualities.
The British physician Sir Thomas Browne proudly described obtaining urine purportedly from the days of Roman emperor Vespasian—over 1500 years old!
Though uroscopy remained common into the 19th century, the practice of collecting urine as medicine thankfully faded away.
Once germ theory identified the spread of contagious microscopic organisms, the sanitary risks of accumulating glass bottles full of piss grew obvious.
The earliest glass bottles manufactured in the American colonies reflect the technical limitations faced by colonial glassmakers.
With no local sources of pure silica sand, the first bottles produced here were made from sand containing high amounts of iron impurities. When heated, these impurities imparted a distinct dark olive hue to the glass.
These crude greenish bottles contrasted sharply with the crystal-clear flint glass coming from England at the time. But the colonists made do with what raw materials they had access to, resulting in sturdy utilitarian bottles that served local needs.
By the mid-1600s, bottle production was underway at early glassworks in Jamestown and Massachusetts.
It wasn't until the 1800s that American glass manufacturing gained access to higher purity sand shipped from the mid-Atlantic region.
Adding manganese purifiers further helped remove the iron tint. This allowed producers to create lighter shades of glass, including the distinctive aqua color associated with early American bottles.
But even when technology permitted, most bottles remained hand-blown using inefficient methods that limited scale.
It wasn't until automated bottle production emerged around 1900 that bottle-making in the US became a powerhouse industry.
No longer constrained by impure ingredients, American factories could pump out vast quantities of affordable bottles in any color imaginable.
The automated bottle machine invented by Michael Owens fundamentally transformed glass bottle production, marking a critical turning point in the industrialization of glass manufacturing.
Prior to Owens' invention in the late 1880s, every single bottle was individually hand-blown by a skilled artisan.
This manual method constrained output. It also led to subtle inconsistencies, as no two glassblowers could form bottles exactly alike.
Owens' automated machine worked by mechanically pressing heated glass into molds with pistons to shape the bottle interior. Air was then blown in to form the outer shape.
With this technology, a small team could produce over 30,000 bottles daily–––far exceeding hand methods.
And the bottles were uniform in size and shape.
The machine’s productivity gains were revolutionary.
Soon, Owens' bottle machines were spreading from factory to factory, displacing traditional glass blowing methods.
By 1910, the majority of American bottle production had converted to automation.
This pivotal shift hugely expanded bottle availability and access.
Once artisanal and bespoke, bottles became a high-volume disposable commodity.
As one of the most recognizable brands in the world, Coca-Cola's iconic contoured glass bottle is deeply intertwined with their corporate history and identity.
The famous Coke bottle shape has an origin story stretching back over a century.
Coca-Cola first began bottling its sodas in 1894 as an alternative to fountain service.
Early straight-sided Coke bottles followed the common medicine bottle style of that era.
Seeking differentiation, in 1915 the parent company sponsored a bottle design contest to create a groundbreaking new bottle with distinct shape and branding.
The winning " contour bottle" design was patented in 1915 and featured the elegant curved cocoa pod shape still used today.
The bottles were custom molded rather than machine made, with the embossed Coca-Cola lettering as part of the intricate shape.
This was the first mass-produced bottle meant for branding over function.
Over the next decades, Coke's contour bottle became iconic, cementing Coca-Cola's image as a classic American brand associated with family life and refreshment.
The bottle design has gone largely unchanged, inspiring customer loyalty and nostalgia throughout the 20th century.
In recent times, Coca-Cola has innovated with plastic packaging but the molded glass contour bottle remains core to their identity.
Billions of Coca-Cola bottles in collectible designs are still produced annually, making it the number one recycled package globally.
After over a century, those graceful sloping bottles remain visual shorthand for Coke itself.
The "growler trade" provides a fascinating look at a bygone custom that employed children to transport beer from taverns to people's homes.
Prior to Prohibition, many states restricted take-away sales of alcohol in sealed containers. However, there was a loophole allowing beer to be dispensed into open pails.
Savvy neighborhood taverns took advantage of this law by hiring local children to shuttle freshly tapped beer to thirsty customers via these open buckets.
The young beer porters, often boys around 12 years old, would make the mile-long journey carrying a wooden bucket yoke with 6 to 8 beer bottles dangling from each side.
The glass bottles clinking back and forth led to the nickname "growlers" for these take-away beer buckets.
A typical growler haul would deliver warm frothy beer to families gathering for dinner or informal social calls. The enterprising kids might make several rounds a day, providing a welcome service in the days before refrigeration and home delivery.
Of course, sending unsupervised children toting alcohol does seem concerning by modern standards!
But the growler trade persisted in cities like New York, Philadelphia, and Chicago into the early 1920s, when Prohibition finally made the practice obsolete.
The ingenuity of bootleggers during Prohibition knew no bounds, as evidenced by the inventive bottle-reshaping methods used to discreetly package illegal liquor.
With alcohol banned nationwide, bootleggers could not simply walk into a store and purchase legitimate flasks.
This led many to take recycling to creative new heights.
Resourceful home brewers and distillers would gather used glass bottles of all shapes and sizes.
They would melt these down by heating them over a metal drum stuffed with burning rags.
Next came the tricky part: shaping the molten glass into the rounded form of a pocket flask.
Some used modified wire coat hangers bent into a makeshift mold. Others relied on wet newspaper or cloth wrappings as a primitive shaper.
After some skillful blowing and rotating, they would produce a crude but serviceable glass flask able to hold a few shots of moonshine.
The end products were irregularly sized with bumpy imperfect seams, but did the job discreetly holding and pouring illegal spirits. These handicraft flasks made from recycled bottles helped underground distributors reuse materials and avoid detection.
For thousands of years, the classic cork stopper reigned supreme as the closure of choice for glass bottles and jars.
From ancient apothecary vials to Victorian era medicine bottles, keeping contents sealed in required a wedge of pressed cork. This made the transition to screw top lids in the early 20th century all the more revolutionary.
The major turning point came in 1932, when American inventor William Painter patented the first twist-off bottle cap for the Crown Cork and Seal Company.
This was the iconic cap we now associate with bottle tops—metal lined with cork cards and sporting a looped opener.
At first, screw caps were slow to displace the traditional cork, facing resistance from traditionalists.
But their convenience and effectiveness soon won out in certain sectors.
Screw tops eliminated the need for a separate bottle opener and provided excellent protection for carbonated beverages.
By the late 1930s, screw top metal caps sealed the majority of beer and soda bottles.
Their lightweight nature was also advantageous during World War II rationing efforts.
Eventually, screw tops became ubiquitous and expanded beyond drink bottles to condiments, medicines, and food jars.
Yet traces of the classical cork cap can still be found on certain wines and spirits upholding time-honored tradition.
The rationing and material shortages that impacted daily life during World War II led to some creative improvisations, including in how bars served beer.
With new beer bottles in short supply, pubs and taverns needed alternatives to continue pouring draught brews.
This necessity sparked a period of novel innovation.
Glass bottles of all kinds were pressed into service transporting ale, lager, and stout from kegs to thirsty customers.
Milk bottles and jugs were common stand-ins, as dairies had extra on hand.
Some establishments went even further afield, serving frothy pints in jelly jars, fruit juice bottles, even kerosene cans if need be.
To cope with the bottle shortage, patrons were encouraged to faithfully bring back empties to be sanitized and refilled.
Bottles were used repeatedly until broken. Draught beers became take-out items poured carefully into a mismatched array of glass vessels.
The mix of determination and unconventional thinking needed in wartime can spur unusual creativity.
While makeshift milk bottle beer service seems odd today, such resourceful improvisation kept neighborhood bars in operation and morale up.
The adoption of the beer can was a gradual revolution that took decades to finally displace the traditional glass bottle.
While canned beer may seem ubiquitous today, it was a novel concept when first pioneered in 1935 by New Jersey's Gottfried Krueger Brewing Company.
At the time, the American Can Company was eager to break into the beer market as Prohibition's end rekindled demand.
So Krueger teamed up with them to conduct the first ever test canning of beer, their Krueger's Finest Beer and Krueger's Cream Ale brands. Early sales were slow, as metal cans were viewed with skepticism.
Over the ensuing decades, brewers like Pabst, Schlitz, and Anheuser-Busch gradually expanded canned offerings. But cans only comprised around 10% of the beer market through the 1970s.
Purists felt cans compromised flavor and preferred the familiar glass bottle.
By the 1980s, however, cans had claimed a majority share.
Their advantages were clear: cans were lighter, easier to transport, cooled faster, and avoided light damage. Specialized can liners maintained taste. And newer aerosol canning technology reduced oxygen contact.
Today, canned craft beers have converted even the most skeptical drinkers. But it took half a century for Gottfried Krueger's pioneering vision to fully transform our conception of how beer should be packaged.
Their risky 1935 experiment with beer cans laid the groundwork for what was to come.
