How to tell if your glass bong is made of high-quality borosilicate glass or cheap glass that might break easily or leach toxins?

If you are a fan of smoking herbs or tobacco with a bong, you might have wondered what kind of glass your bong is made of. Is it high-quality borosilicate glass that can withstand heat and shock, or is it cheap glass that might crack, shatter or release harmful chemicals into your smoke? In this blog post, we will explain the difference between borosilicate glass and regular glass, and how to tell them apart when buying or using a glass bong.

What is borosilicate glass?

Borosilicate glass is a type of glass that contains boron trioxide, which makes it more resistant to thermal expansion and shock than regular glass. Borosilicate glass has a very low coefficient of thermal expansion, which means it does not expand or contract much when exposed to temperature changes. This makes it ideal for laboratory equipment, cookware, and of course, bongs.

Borosilicate glass can withstand temperatures up to 515 degrees Fahrenheit, and can handle sudden temperature changes without cracking or breaking. This is important for bongs, because you don’t want your bong to shatter when you light up your herb or tobacco, or when you rinse it with cold water after use.

Borosilicate glass is also chemically inert, which means it does not react with other substances or leach any harmful chemicals into your smoke. Some cheap glass bongs may contain lead, cadmium, or other toxic metals that can be released when heated, posing a health risk to you and the environment. Borosilicate glass is safe and eco-friendly, as it does not contain any harmful additives.

What are the benefits of borosilicate glass bongs?

Besides being more durable and safer than regular glass bongs, borosilicate glass bongs also have some other advantages. For example:

  • Borosilicate glass bongs are easy to clean and maintain, as they do not stain or retain odors from your smoke. You can simply rinse them with hot water and soap, or use some alcohol or vinegar to remove any residue.
  • Borosilicate glass bongs are transparent and clear, which allows you to see the smoke and water inside your bong. This can enhance your smoking experience, as you can watch the bubbles and percolators in action. You can also easily check the water level and cleanliness of your bong.
  • Borosilicate glass bongs are aesthetically pleasing and elegant, as they come in various shapes, sizes, colors and designs. You can find borosilicate glass bongs with beakers, straight tubes, bubblers, recyclers, ice catchers, ash catchers, percolators, and more. You can choose a bong that suits your style and preference.

How to tell if your glass bong is made of borosilicate glass?

Unfortunately, not all glass bongs are labeled or advertised as borosilicate glass. Some sellers may claim that their bongs are made of borosilicate glass, but they are actually made of cheap glass that can break easily or leach toxins. So how can you tell if your glass bong is really made of borosilicate glass?

Here are some tips to help you identify borosilicate glass bongs:

  • Check the price. Borosilicate glass is more expensive than regular glass, because it requires more skill and precision to make. If a glass bong is very cheap, it is probably not made of borosilicate glass.
  • Check the weight. Borosilicate glass is denser than regular glass, which means it is heavier for the same size. If a glass bong feels too light or thin for its size, it is probably not made of borosilicate glass.
  • Check the sound. Borosilicate glass has a higher pitch than regular glass when tapped or clinked. If a glass bong sounds dull or low-pitched when tapped or clinked, it is probably not made of borosilicate glass.
  • Check the quality. Borosilicate glass is smooth and flawless, without any bubbles, cracks, scratches, or imperfections. If a glass bong has any defects or signs of poor craftsmanship, it is probably not made of borosilicate glass.
  • Check the reputation. Buy your glass bongs from reputable and trustworthy sellers, who can provide you with information and guarantees about the material and quality of their products. You can also read reviews and feedback from other customers, or ask for recommendations from your friends or fellow smokers.
