Featuring an opaque quartz surface & clear quartz bottom lip.
The bottom lip creates a pocket of air underneath the insert. This air pocket regulates heat transfer, preventing your oil from heating up too fast or getting too hot.
Unlike regular cold starts cooling down as soon as you stop torching it, our cold start insert maintains temperature as the heat slowly transfers from the banger to the insert.
With our cold start inserts you don’t have to wait for your banger to cool down to start another cold start.
We recommend using a v4 Banger with heat up times of 25-35 seconds depending on amount of oil.
