Have you ever heard of a Prince Rupert’s Drop? If not, let me introduce you to this fascinating object. A Prince Rupert’s Drop is formed by dripping molten glass into cold water, creating a unique phenomenon in material science. The outer layer of the drop is under extreme compressive stress, while the interior is under high tensile stress. This means you can hit the bulbous end with a hammer without breaking it, but if you damage the tail, the entire drop shatters explosively.
In a recent experiment, I attempted to capture the explosion of a Prince Rupert’s Drop encased in epoxy resin. This sparked a discussion among viewers about the materials and methods used, such as the type of epoxy and the vacuum process involved. Cal Breed, the creator of the original Prince Rupert’s Drop, suggested an intriguing idea: instead of using epoxy, why not encase the drop in molten glass?
Cal Breed owns Orbix Hot Glass, a studio known for crafting unique glass pieces. We decided to explore the idea of encasing a Prince Rupert’s Drop in molten glass using colored glass, specifically ice blue glass. This required careful handling due to its distinct properties.
The process began by heating the glass to a precise temperature to keep it malleable. The artists at Orbix possess an intuitive understanding of glass, allowing them to adjust their techniques based on the material’s behavior. This differs from an engineer’s approach, which is often more analytical.
Cal explained that different colors in glassmaking have unique densities and properties, affecting their behavior when heated. The team prepared to create individual Prince Rupert’s Drops by breaking the blue glass into smaller pieces and forming them into balls.
Glass artists use specific techniques to create weak points in the glass, enabling them to detach it from the blow pipe or punty rod. Understanding these stress points is crucial, as glass behaves differently than metals like aluminum or steel.
The team attempted to encase the Prince Rupert’s Drop in molten glass, a process requiring precise timing and temperature control. After several trials, they refined their methods and improved their teamwork, eventually succeeding in creating a new piece.
The completed piece was placed in an annealer to relieve internal stresses. Once cooled, it was polished and refined in the cold shop, where Cal used various tools to achieve the desired finish.
This project provided me with a deeper understanding of glass’s material properties and the creative process involved in glassmaking. The collaboration between art and science was evident, and the final pieces showcased the skill and knowledge of the artists at Orbix Hot Glass.
If you’re interested in owning one of these unique pieces, they will be available on Cal’s website. Thank you for joining this exploration of glassmaking, and I hope you found it as insightful as I did.

Do you know what this is? If you do, you might be interested in this video. If not, let me explain. This is called a Prince Rupert’s Drop, created by dripping molten glass into water. This process results in a unique material science phenomenon where the exterior of the drop experiences extremely high compressive stress, while the interior is under high tensile stress. This means that you can strike the tip with a hammer without breaking it. However, if you damage the tail, it will explode.
In this video, I cast a Prince Rupert’s drop in epoxy resin and attempted to capture the moment of its explosion. Some viewers raised questions about my methods, such as the type of epoxy used and the vacuum process. While these are valid points, one individual, Cal Breed, who created the original Prince Rupert’s drop, asked whether epoxy was necessary and suggested using glass instead. This led to the idea of placing a Prince Rupert’s drop in molten glass and observing the results.
Cal Breed is the owner of Orbix Hot Glass, where we explored this concept. The team at Orbix Hot Glass specializes in creating unique glass pieces. We decided to use colored glass, specifically ice blue glass, which requires careful handling due to its properties.
The process involves heating the glass to a specific temperature to ensure it remains malleable. The artists at Orbix have an intuitive understanding of glass that differs from an engineer’s perspective. They can feel the material’s properties and adjust their techniques accordingly.
As we worked, Cal explained the significance of different colors in glassmaking. For instance, certain colors have varying densities and properties that affect how they behave when heated. The team prepared to create individual Prince Rupert’s drops by breaking up the blue glass and forming it into balls.
The glass artists utilize techniques to create weaknesses in the glass, allowing them to break it off from the blow pipe or punty rod. Understanding the stress points in glass is crucial, as it behaves differently than metals like aluminum or steel.
The team then attempted to place the Prince Rupert’s drop into molten glass. However, the timing and temperature management were critical to ensure success. After several attempts, they refined their process and improved their teamwork.
Eventually, they successfully created a new piece, which was then placed in an annealer to relieve internal stresses. The final pieces were polished and refined in the cold shop, where Cal used various tools to achieve the desired finish.
Throughout this process, I gained a deeper understanding of the material properties of glass and the creative process involved in glassmaking. The collaboration between art and science was evident, and the final pieces were a testament to the skill and knowledge of the artists.
If you are interested in purchasing one of these unique pieces, they will be available on Cal’s website. Thank you for watching, and I hope you found this exploration of glassmaking insightful.
