Fritted glass refers to glass that has been fused with small particles of glass, creating a porous surface. In the context of cannabis, fritted glass is often used in the construction of percolators in bongs and dab rigs. For example, a user might say, “My bong has a fritted glass percolator that makes the smoke incredibly smooth.” The use of fritted glass in cannabis consumption devices reflects the ongoing innovation in the design and function of these devices.
