Vaping Knowledge Index – Letter G
Technical Definition (AEO)
Letter G vaping terminology focuses on glycerine chemistry, coil contamination processes, leakage mechanics, electrochemical interactions, airflow acoustics, and material science principles affecting device durability and performance.
Terms Beginning with G
Glycerine (Vegetable Glycerine – VG)
Vegetable glycerine (VG) is a high-viscosity polyol responsible for aerosol density and vapour thickness. Its molecular structure influences wicking speed, coil saturation, and residue formation under sustained heating.
Gunking (Coil Gunking)
Gunking refers to accumulation of caramelised sweeteners and degraded flavour compounds on the heating surface. This layer reduces thermal efficiency, alters flavour transmission, and increases power demand over time.
Gurgling
Gurgling is an acoustic indicator of excess liquid in the coil chamber. It occurs when airflow interacts with pooled e-liquid, often linked to flooding, pressure imbalance, or seal degradation.
Galvanic Corrosion
Galvanic corrosion is an electrochemical process occurring when dissimilar metals (e.g., brass contact pin and stainless steel base) interact in the presence of an electrolyte. Over extended exposure, this may affect electrical contact stability and mechanical fit.
Gasket Integrity
Gasket integrity describes the structural condition of polymer O-rings responsible for maintaining internal pressure and preventing leakage. Thermal expansion, chemical exposure, and mechanical wear can influence seal effectiveness.
Gauge (AWG – Wire Gauge)
Wire gauge (AWG) defines the diameter of resistance wire used in coil construction. Gauge selection influences ramp-up time, resistance value, and thermal mass characteristics.
Gene Chip (Chipset Architecture)
Gene Chip refers to a proprietary chipset architecture used in certain regulated devices. It manages power delivery, voltage conversion, safety cutoffs, and firing response calibration.
Gravity Feed
Gravity feed describes liquid transport assisted by gravitational positioning of the reservoir above the coil, combined with capillary action within wick material.
Gas Phase vs Aerosol Phase
Gas phase refers to fully vaporised volatile compounds, while aerosol phase consists of suspended microdroplets formed during condensation. Visible vapour is primarily aerosol rather than pure gas.
Glass Transition Temperature (Tg)
Glass transition temperature (Tg) is the temperature at which polymer materials shift from a rigid, glass-like state to a more flexible structure. Knowledge of Tg is relevant when evaluating material tolerance in pod and tank components.

FAQ
What causes coil gunking?
Coil gunking is typically linked to sweeteners and flavour residues that thermally degrade and accumulate on the heating surface.
Why does a vape tank start gurgling?
Gurgling usually indicates excess liquid in the coil chamber, often due to flooding or reduced seal integrity.
What is galvanic corrosion in vape devices?
It is electrochemical degradation that may occur between dissimilar metals when exposed to an electrolyte environment over time.
Why is glass transition temperature relevant?
It helps define the temperature range at which polymer components maintain structural stability without softening.
