The United States Environmental Protection Agency reports that recycling one ton of glass can save more than a ton of carbon dioxide from being released into the atmosphere.

86. Fulgurite Glass forms when cloud-to-ground lightning occurs.

The intense heat from the lightning melts sand or rock and fuses it into a natural glass tube. Fulgurite is found on every continent and is relatively common in the United States, especially in Florida.

87. Meteoritic Glass or Tektite glass forms due to the collision of a meteorite with the earth’s surface.

The resulting high-velocity impact melts the ground and hurls fragments of rock and dirt into the air. As these materials fall back to earth, they cool rapidly and form a natural glass. Tektites are named for their place of origin; tektos is Greek for “molten.”

88. In 1871, William Pilkington invented the machine that allowed large sheets of glass to be made.

The machine that Pilkington invented was a float glass process, which is still used today to produce large sheets of high-quality glass. The float glass process involves floating molten glass on a bed of molten metal, usually tin. This allows the glass to cool evenly and creates a smooth surface.

89. The soda-lime glass is the most commonly used type of glass.

90. Modern glass variants are produced from float glass.

The invention changed the construction industry and resulted in the widespread use of glass in architecture.

91. Dale Chihuly is world-renowned for incorporating his glass sculpture art into a variety of indoor and outdoor environments.

One of his most famous pieces is the “Mille Fiori” which means “thousand flowers.” The sculpture is on display at the Bellagio Resort and Casino in Las Vegas, Nevada.

92. The intricate art of glass painting was once the most dominant form of painting in Europe.

Glass painting can be used to create beautiful works of art, or simply to add a touch of color to plain glassware. The medium is very versatile and can be used in a variety of ways.

93. Stained glass was installed in Catholic churches as a way of telling stories from the Bible through images instead of text.

The artform flourished in Europe during the Middle Ages, with some of the most famous examples coming from Gothic cathedrals such as Notre Dame and Westminster Abbey.

94. Colored glass is achieved by adding metallic oxide powders to molten glass.

The oxide powder fuses with the glass to form a new compound, which imparts color. The type and amount of oxide used determines the final color of the glass.

95. The manufacture of stained glass is a recognized art form

Stained glass artists are usually trained through an apprenticeship or at a specialized art school

96. Stained glass, or ‘art glass’ is most common in places of worship, but can also be found in other significant buildings, both institutional and commercial, and in private homes.

97. Glassblowing is often a team effort.

The person who actually forms the glass into a shape is called the gaffer, while their assistants are called “off-hand” workers.

98. Glassblowing requires incredibly high temperatures.

The furnace must be kept at around 2,100 degrees Fahrenheit (1,149 degrees Celsius) to melt the glass. The molten glass is then gathered on the end of a long metal blowpipe.

99. Glass art must be cooled very slowly

It is to avoid cracking or shattering

100. You won’t die if you inhale through a blowpipe.

The air has time to cool before reaching your lips since the blowpipe is made of steel and the tube is relatively long and narrow.

101. Annealing is a critical step in the creation of glass art

The ideal annealing temperature for most types of glass is between 520 and 650 degrees Fahrenheit (270 to 345 degrees Celsius). By cooling the glass slowly, the artist can avoid any thermal shock that could damage the piece.
