As we all remember from science class, matter expands when heated and contracts when cooled. Metal and quartz expand and contract at different rates. If the metal heat coil contracts faster than the quartz while cooling, the coil may fall off the banger. If the metal does not expand enough while heating up and is very tight around the quartz, that may result in cracking or shattering. Even if it doesn’t happen the first time, repeated heating and cooling will weaken the glass and likely form one or more cracks in your daily driver. This can also be very dangerous if flammable materials are underneath the dab rig.
With the set-up pictured above we have a metal coil heating a quartz cup, so to speak. One has to fit inside the other, but not too snugly and not too loosely. This is doubly-true for the heating coil around the banger nail.
The Old Solution
The early days of e-nail quartz setups featured the side-arm design which incorporated a quartz hook that was fused into the side of the banger itself. This proved to be difficult to get a really good fit without making it impossible to fit the coil around the bucket. The delicate arms were prone to breakage for this reason. More recently, better designs have come along to hold a coil up to a banger nail. Here we offer some handy solutions to help keep a heating coil secured to a quartz banger:
The Cheap, Easy Wire-Tie Method
A typical quick-fix solution is using a bit of wire to secure the two parts together. Many users may prefer this fix, since the wire is easily replaced if need be. The wire bag-ties available in the produce section of a grocery store will suffice as a substitute. It’s not the prettiest solution, but it works. The only snag is disassembly after use. Rather than untwisting the wire, most users opt to simply cut the wire off and bust out a new one for the next time.
If you apply wire to secure the heater coil to the banger, you’re best off using a pair of needle-nosed pliers. Tip: making sure the tabs are completely horizontal while twisting will make a tighter connection than if they are more parralel to each other. Twist exactly like you would when closing a plastic bag, but like you mean it…
