Your EQ's crucible is where all the actual vaporization happens, and DaVinci gives you a choice: quartz or zirconia. Here's how to decide which one belongs in your rig.
Quartz: The Flavor Standard
Quartz heats quickly and is chemically inert, meaning it doesn't affect the taste of your concentrate at all — what you load is what you taste. The tradeoff is that quartz is more fragile than zirconia and can show residue buildup faster, which means slightly more frequent cleaning if flavor purity is your top priority.

Zirconia: Built for Heat Retention
Zirconia holds heat longer and more evenly than quartz, and it's noticeably more durable — a better fit if you're hard on gear or want fewer replacements over time. Flavor purity is very slightly behind quartz, but for most users the difference is marginal against the added durability.

So Which Should You Buy?
- Chasing the cleanest possible flavor and don't mind more frequent cleaning → Quartz
- Want durability and consistent heat retention session after session → Zirconia
- Not sure yet → many EQ owners keep one of each and swap based on mood, since both install the same way
Because the EQ's crucible is fully swappable, this isn't a permanent decision — you can own both and switch depending on what a given session calls for.
