The possibilities of recycled glass seem to be endless, as it has proven effective in hand blowing, fusing, kiln-casting, and sandblasting. Worldwide, artists continue to find new and exciting ways to turn trash into treasures.

Because it does not lose its chemical purity overtime, glass is the ideal product to use for artists looking to minimize waste in landfills and lessen the impact on the environment. All over the world recycled glass is being utilized to create public structures, interior designs, and functional objects. This is not a new discovery, as glass has likely been recycled since ancient times, and individual glass artists have been working with recycled glass for several decades. In many cases, glass studios who utilize recycled glass not only benefit their environment, but their communities by employing and providing job security to the locals for work them.

What is Sea Glass?

Sea Glass is fragments of glass, usually from broken bottles and jars, that have been frosted and softened by the effects of water currents and surrounding minerals. As the name would suggest, it is most often found along ocean beaches, but can also be found on the shorelines of lake and rivers. Genuine sea glass has spent years, or possibly decades, being morphed by the forces of nature. While not exactly "recycled" glass, it has become a popular collector's item for many beachgoers and some creative collectors have repurposed these weather-worn items into jewelry and works of art. However, certain artists have taken to creating their own sea glass, usually with a rock tumbler. Though controversial among genuine sea glass collectors and artists, it does allow glass to be recycled or repurposed by artists who may not have access to genuine sea glass.

Unlike small businesses and studios, companies and corporations often function on a much larger scale. Therefore, proper waste management is essential if the glass industry is to make an impact on the fight against climate change. Even the ancient Romans implemented reuse and recycling of materials into their economy. With sustainability at the fore front of many consumer affairs, industries worldwide are looking to streamline their process of recycling. Given the chemical make-up of glass, and the fact that it maintains its purity, glass is overall an easy material to recycle. However, as glass has come into contact with other elements in laboratories and consumer electronics, the process of recycling glass has become more complicated than in previous decades. From test tubes to phone screens, recycling of glass is something that nearly every manufacturer must consider if they are to regard themselves as sustainable and ecological minded.
