Quick Links
During most of the game’s time in early access,The Planet Crafterfeatured a fictional mineral called pulsar quartz. This material was (and still is) essential for many late-game machines, including fusion generators and teleporters.
But as of the “Procedural Wrecks” update, the developers ofThe Planet Crafteradded four new types of star-inspired quartz: blazar quartz, quasar quartz, magnetar quartz, and solar quartz. Each one is named after a kind of cosmic phenomenon, and you can find all of them on the planet if you know where to look.

Where To Find Every Quartz In The Planet Crafter
One of the first places you should look when you start to need quartz types beyond pulsar is inthe Rainbow Cavesat the north end of the map. You can find the west end of the caves in theHighlands biometo the northwest, and the east end connects to theGrasslands biome, which is north of theDune Desert.
If you visit the Rainbow Caves early on in the game, they’ll appear as ice-covered rocks. Unfortunately, this ice also blocks several cave entrances, and you’ll have to wait until the Terraformation Index reaches 425 GTibefore the ice starts melting. Before then, you can still enter the two pulsar quartz caves and one of the magnetar caves. By the time the ice melts, this area will feature a river running through a canyon and all kinds of plant life.

The Rainbow Caves live up to the name thanks to the many colors of quartz you can find inside. You also get an achievement for finding the caves and one more for mining your first solar quartz. Each quartz type comes in a different color:
Solar Quartz
Yellow
If you end up finding the rarer quartz types before theFish or Amphibian Terraformation stages, be sure to store them in a safe place that’s out of the way. You won’t need any quartz types beyond pulsar before this point, but they become essential once you do.
How To Get Quartz In The Late Game Of The Planet Crafter
The Rainbow Caves have plenty of each type of quartz, but their supplies are limited. Unlike other basic materials, you can’t generate more quartz with ore extractors.Even an Ore Extractor T3inside the Rainbow Caves won’t give you quartz.
Instead, the best way to gather more quartz is to checkcrates and safesafter you reach theFishorAmphibian stage of development. It’s at this point that every quartz variety will start appearing as random loot.

If you want a consistent supply, you should create thePortal Generator(which unlocks at 250 GTi). This generator lets you explore distant, procedurally generated shipwrecks, giving you an infinite supply of new crates to open. You’ll need quartz to open a portal, but you can find more quartz than you spend if you thoroughly explore each location.
