How to Tell if a Glass Bong is High-Quality or Low-Quality by Looking at It?

If you are a fan of smoking herb or tobacco, you might have considered buying a glass bong to enhance your experience. Glass bongs are popular among smokers because they offer many benefits, such as:

  • They preserve the flavor and aroma of your herb or tobacco better than other materials.
  • They are easy to clean and maintain, as long as you do it regularly.
  • They come in various shapes, sizes, colors, and designs, so you can find one that suits your style and preference.
  • They have different features and accessories, such as percolators, ice catchers, ash catchers, and more, that can improve the filtration and cooling of the smoke.

However, not all glass bongs are created equal. Some are made with high-quality materials and craftsmanship, while others are cheap and low-quality. How can you tell the difference by just looking at them? Here are some tips to help you spot a high-quality glass bong from a low-quality one.

Check the Material

The first thing you should look at when buying a glass bong is the material it is made of. The best glass bongs are usually made with quality borosilicate glass, which is a type of scientific-grade glass that is resistant to heat and thermal shock. Borosilicate glass is also clear and durable, and it does not affect the taste or smell of the smoke.

On the other hand, low-quality glass bongs are often made with cheap or recycled glass, which is more prone to cracking, breaking, or melting. Cheap glass can also leach chemicals or impurities into the smoke, affecting its quality and safety. You can tell if a glass bong is made with cheap glass by looking for bubbles, scratches, cracks, or unevenness in the surface.

Check the Thickness

The next thing you should look at when buying a glass bong is the thickness of the glass. The thicker the glass, the more durable and stable the bong will be. Thicker glass can also withstand higher temperatures and pressures without breaking or deforming. The ideal thickness for a glass bong is between 3mm and 9mm, depending on the size and shape of the bong.

However, some low-quality glass bongs may try to trick you by making the base or the mouthpiece thicker than the rest of the body. This creates an illusion of thickness, but it does not provide enough strength or support for the whole bong. You can tell if a glass bong has uneven thickness by holding it up to the light and looking for variations in color or transparency.

Check the Welds

The third thing you should look at when buying a glass bong is the welds or joints that connect different parts of the bong. The welds should be smooth, even, and seamless, without any gaps or cracks. The welds should also be aligned and symmetrical, without any misalignment or distortion. The welds should also be strong enough to hold the weight and pressure of the water and smoke.

On the contrary, low-quality glass bongs may have sloppy, uneven, or visible welds that can compromise the integrity and functionality of the bong. Poor welds can also create weak points that can break or leak easily. You can tell if a glass bong has poor welds by looking for bubbles, cracks, discoloration, or roughness in the joints.

Check the Features

The last thing you should look at when buying a glass bong is the features or accessories that come with it. Some features that can enhance your smoking experience are:

  • Percolators: These are devices that create bubbles in the water chamber to filter and cool the smoke. There are many types of percolators, such as showerhead, honeycomb, tree, inline, matrix, turbine, etc. Percolators can improve the smoothness and flavor of your hits.
  • Ice catchers: These are notches or pinches in the neck of the bong that allow you to put ice cubes in it. Ice catchers can cool down the smoke even more before it reaches your mouth.
  • Ash catchers: These are attachments that go between the bowl and the downstem of the bong. Ash catchers prevent ash and debris from entering the water chamber, keeping it cleaner and fresher.

However, not all features are created equal. Some high-quality glass bongs have features that are well-designed, well-made, and well-integrated into the bong. These features work efficiently and effectively, without causing any problems or drawbacks. For example, a good percolator should create enough bubbles without creating too much drag or splashback.

On the other hand, some low-quality glass bongs have features that are poorly-designed, poorly-made, or poorly-integrated into the bong. These features may not work properly or may cause more harm than good. For example, a bad percolator may create too little bubbles or too much drag or splashback.

You can tell if a glass bong has good or bad features by looking for signs of quality and performance, such as:

  • The size and shape of the holes or slits in the percolator.
  • The number and placement of the percolators in the bong.
  • The amount of water and ice needed to fill the bong.
  • The ease of cleaning and maintenance of the bong.


Buying a glass bong can be a rewarding investment for your smoking pleasure, but you need to be careful and smart when choosing one. A high-quality glass bong can last you a long time and provide you with smooth, pure, and flavorful hits. A low-quality glass bong can break easily and ruin your smoking experience.

To tell if a glass bong is high-quality or low-quality by looking at it, you need to check four things: the material, the thickness, the welds, and the features. By following these tips, you can avoid wasting your money on a bad bong and find the perfect one for you.
