Quartz Nail
A heat-retaining quartz dish or banger used to vaporize cannabis concentrates in a dab rig.
Quartz nails are the default dabbing surface for a reason: they heat fast, cool fast, taste clean, and don't off-gas at reasonable temperatures. The folklore around 'medical grade' or 'pure' quartz is mostly marketing — purity claims are rarely verified. What actually matters is wall thickness, joint fit, and not torching your banger red-hot every session. Low-temp dabs (around 500–600°F surface temp) preserve terpenes and reduce benzene formation compared to ripping it hot.
Definition
A quartz nail is a heat-resistant dish — usually shaped like a small bucket (a 'banger') — made of fused quartz and attached to a dab rig via a ground glass joint. The user heats the quartz with a butane torch (or an e-nail coil), lets it cool to a target temperature, then drops a small amount of cannabis concentrate onto the inner surface, where it vaporizes.
Why quartz
Fused quartz is favored over titanium and ceramic for three practical reasons: it imparts no metallic taste, it has a relatively fast thermal response, and it is chemically inert at dabbing temperatures. Quartz softens around 1650°C, well above any torch flame application [1]. Concentrate vaporization happens efficiently in the ~315–450°C (600–840°F) range, with lower temperatures preserving more monoterpenes and higher temperatures producing more thermal degradation products including benzene, toluene, and methacrolein Strong evidence[2][3].
What it does
- Provides a clean, inert surface for flash-vaporizing concentrates.
- Retains heat long enough for a full dab without re-torching.
- At low temps (~500–600°F surface), preserves terpene flavor Weak / limited.
- At high temps (>750°F), vaporizes more completely but generates more harmful byproducts Strong evidence[3].
What it doesn't do
- It does not filter or purify vapor — whatever is in the concentrate ends up in your lungs.
- 'Medical grade' or '99.99% pure' quartz claims from vendors are largely unverified marketing No data.
- It will not last forever. Repeated thermal shock and residue buildup ('chazzing') cloud the surface and degrade flavor over time.
- It does not eliminate combustion risk if overheated or if residual butane from a torch is inhaled.
