Abstract
The present disclosure is directed to glass spheroids and methods of making these spheroids that have significantly increased resilience to applied pressure and surface scratching. In addition, the present disclosure is directed to tailless Prince Rupert's Drops and methods of making tailless Prince Rupert's Drops.
Claims30
A method of making a glass spheroid comprising:
- melting spheroid material;
- adding the melted spheroid material to a heated channel;
- rolling the melted spheroid material back and forth on the heated channel into a molten bead comprising the melted spheroid material;
- and
- rolling the molten bead into a cooling environment comprising a cooling fluid, thereby forming a glass spheroid.
A method of making a glass spheroid comprising:
- adding molten spheroid material to a heated mold;
- applying a continuous pressure to the heated mold;
- and
- immersing the mold into a cooling environment comprising a cooling fluid, thereby forming a glass spheroid in the mold.
A glass spheroid having a diameter between 4 mm to 12 mm and having a compressive strength of at least 250,000 psi.
A close sphere packing matrix comprising glass spheroids having a diameter between 4 mm to 12 mm and having a compressive strength of at least 250,000 psi.
