It actually isn't necessary to season a quartz banger before using it unlike titanium nails, but some people believe that it can help improve the performance and flavor of the banger over time. Seasoning a quartz banger involves heating it to a high temperature and then allowing it to cool down, which can help to remove any impurities or manufacturing residues that may be present on the surface of the banger, but this is actually not true since a banger is heated to over 2000 degrees when its being produced and a simple home torch can't get anywhere near this temp.
Its also risky to do so as heating up the whole banger body makes handling the banger trickier and can cause user error like dropping or the mishandling the scorching hot banger causing damage to either the banger or property, or worst causing injury.
Either way, its a matter of personal preference to season or not to season. If you decide to season your quartz, do so carefully and follow appropriate safely precautions. If you are unsure about the process, its best to consult experts or just skip the process altogether.
