A 14-inch double percolator glass bong is a water pipe designed for enhanced filtration and smoothness while smoking. Here's a detailed breakdown of the features you can expect with this type of bong:

Double Percolators:

• Percolators (percs) diffuse the smoke through water for added filtration.

Common types of percolators include:

• Tree Perc: Multiple arms for maximum diffusion.
• Honeycomb Perc: A disc with multiple holes for efficient percolation.
• Shower head Perc: A vertical tube with slits, providing a shower-like filtration.
• Having two percolators means the smoke is filtered twice, giving you smoother hits.

Height:

• 14 inches (35.56 cm) is a medium-to-large size, offering a good balance of portability and functionality.

Material:

• Typically made from borosilicate glass for durability and heat resistance.

• Many models feature an ice pinch to hold ice cubes, further cooling the smoke for a smoother experience.

Down stem and bowl:

• Usually includes a removable down stem (often diffused) and a matching glass bowl.

Base:

• Comes with either a beaker base for stability or a straight tube design for a sleek look.

Benefits:

• Smooth Hits: Double percolation ensures reduced harshness by filtering out impurities and cooling the smoke.
• Reduced Coughing: Enhanced filtration makes it easier on the lungs.
• Aesthetic Appeal: Intricate percolator designs are visually appealing.

Cleaning Tip:

• Double percs can be harder to clean, so use isopropyl alcohol and salt for thorough cleaning. Consider using bong cleaner solutions or cleaning plugs to keep it in top shape.
