Heat up the glasses in kilns to around 1100 °F
Heat the face of the glass with a torch and poke it with a special rod
The glasses then go back in the kiln to cure and cool down for 10 to 15 hours
Glue a lead-free bullet or a golf ball into the glass
Each glass is different and has its own unique character depending on the person who is crafting it, the temperature of the glass and the position of the bullet.
