First, let's learn about the history of bong
Excavations of a kurgan in Russia in 2013 revealed that Scythian tribal chiefs used gold vessels 2400 years ago to smoke cannabis and opium. The kurgan was discovered when construction workers were clearing land for the construction of a power line.
During the reign of Emperor Akbar, physician Hakim Abul Fath invented the waterpipe in India, and discovered tobacco. Abul suggested that tobacco "smoke should be first passed through a small receptacle of water so that it would be rendered harmless". Other sources also show evidence of the invention of the waterpipe in China during the late Ming Dynasty (16th century), along with tobacco, through Persia and the Silk Road.
Next, let's take a look at the steps of making a glass bong-the art of glassblowing
Big ones, small ones, some as big as your head; glass bongs come in all shapes and sizes. Their construction isn't the result of complex machinery, but the highly skilled techniques of expert glass blowers.
The first step is to put the small amount of silver or gold into the glass. We call this process "fuming" - "silver fuming" if using silver and "gold fuming" if using gold. After this the colors can be added on to the glass. This could vary and depends on the product. Some products are heavily fumed without additional colors, some are fumed less with lots of colors. The deposited colors are processed in several different ways and techniques. This creates the original colored patterns.
Second, to provide a more uniform design (an integral feature of making bongs), blown glass bubbles can be added to the lathe to ensure a consistent cylindrical design. Additional blowtorches can be applied to the glass structure to help create or add guts, percolators, or any other elaborate feature imaginable.
The glassblower is blowing out the bowl and shaping the shape with his breath. Larger double bowl bongs are machined in segments. After blowing out the basic shape, other surface glass decorations can be added. E.g. Decoration for hookah holder or slider holder. The holes in the slider and carb are also heated and blown out, making the ice trap. After a while, when the bowl is slightly cooler, cut away the remaining material and soften and adjust the rim.
The cooling process of each glass sheet is also important. The heavier the product, the longer it will take to cool. We use special ovens for slower cooling of newly made products, which makes the glass more durable. If the glass cools too quickly, even if it's just sitting on a shelf, it will crack in the future.
