We can’t go throughout our day without coming into contact with some sort of glass. It’s in our buildings, in walls, windows, and fiberglass insulation. Specialty glass is in our cars, used to prevent large shards of glass from forming in the case of an accident. Glass is found in our homes, our mirrors, furniture, laptops, televisions, dishes, and decorations. Not to mention, the glass that you probably touch every day on your smartphone. You may even be wearing glass to help you read this article.

Then there is the glass we don’t think about in our day-to-day life, like bullet-proof glasses, glass tools and containers in laboratories, glass made to be building exteriors, and the glass that is used in technology, making up the tiny bits and pieces that make our machines work, like camera lenses and copiers.

Despite all of its uses, the majority of us are unaware of who makes our glass products and where they come from.

To alleviate the confusion, we’ve compiled a list of the top ten glass suppliers in the world.

1. Beijing Glass Group

   2021 Annual Revenue: $80.44 billion

   Headquartered in, you guessed it, Beijing, this company comes from the Peking Glass company, which was founded in 1940. This company produces industrial and technical glass as well as eyewear, and quartz and silicon materials. They also produce photovoltaic cell components, which are the parts that make up solar panels and allow us to transform sunlight into energy. Information on their revenue and number of employees was not available, and because of this, we have put them at the bottom of our listing.

   Glass manufacturers supply us with millions of modern-day products and solutions, those we can take for granted, and those we do not even think about. So, next time you look in the mirror, wash a dish, or roll down your car window, take a moment to mentally thank the glass manufacturers of the world.

2. Saint Gobain

8. Pilkington

   2021 Annual Revenue: $593.4 million

   Originally founded in 1826, this glass manufacturer has been a subsidiary of Nippon Sheet Glass since 2006. However, their sales are so substantial, for this list, we decided to view their revenues separately. They are headquartered in Lancashire, England, and have become a major supplier of toughened automotive, aerospace, and building glass across the world.

   Their acquisition by NSG was a deal made out of necessity. Their competitor, Asahi Glass Co. owned around 25% of the global market at the time of the deal. On their own, neither company could compete, but together, they would dominate an equal share of the market. Today, both of the companies make a combined $9.5 billion, making them a more fearsome competitor to Asahi, which makes $11 billion.

   Annually, Pilkington receives $4.5 billion in revenue, and they employ around 24,000 people worldwide.

Despite their size, their accomplishments in the industry have earned them a place on this list, among the big dogs of the industry.
