Find out how bubble glass pillars are made

Posted on

Bubble glass pillars, also known as bubble columns or bubble-infused glass pillars, are created by incorporating bubbles or air pockets within the glass structure. Used along with LED Lights effect these Glass Pillars look great as a home interior product. This effect can be achieved through a variety of techniques. Here’s an overview of a common method used to make bubble glass pillars:


  1. Gathering the glass: The pillar structure is created using molten glass from a furnace using a blowpipe or a similar tool.
  2. Preparing the bubble effect: To create the bubble effect, the glassblower introduces air or gas into the molten glass. This can be done by blowing air through the blowpipe, using a compressed air source, or employing specialized tools like a bubble-blowing wand.
  3. Shaping and forming: The glassblower shapes and manipulates the molten glass to the desired pillar form, ensuring that the bubbles are evenly distributed throughout the glass. They may use techniques like blowing, rolling, stretching, and twisting to achieve the desired shape and pattern of bubbles. The most famous are round, square and rectangle glass pillars.
  4. Annealing: Once the bubble glass pillar has been formed, it is placed in a kiln for annealing. Annealing involves controlled cooling of the glass to relieve internal stresses and increase its strength. This step is crucial to prevent the formation of cracks or fractures due to temperature changes.
  5. Cold working and finishing: After annealing, the glass pillar may undergo additional cold working processes such as grinding, polishing to refine the surface and enhance its visual appeal.

It’s worth noting that specific techniques are used to create different sizes, distribution, and density of the bubbles.
