Fire cut style is a popular glassblowing method of piercing glass with tiny holes as a way of diffusion. Most of the time this process is seen only on downstems. But this piece incorporates it to the percs! The fire cut holes can be seen on the two inset percs located in the main chamber of the bong. One hangs into the chamber from the top while the other is attached to the base of the bong, which is about 4.25 inches wide. Each have a great deal of holes that diffuse smoke for a more refreshing taste. The smoke is led into the bottom fire cut inset perc by way of circular tubing, resembling a doughnut. This donut perc is directly attached to the 18mm female joint of the Fire Cut Inset to Donut Perc Big Bong. Perhaps the most noticeable part of the Fire Cut Inset to Donut Perc Big Bong is the triple ice catcher located in the center of the water pipe. While most of the ice will sit on top of the first set, this gives you the option of using crushed ice. The combination of filtration, large packs, size, and ice will give you consistent hearty hits that taste great!
