Can you put quartz in an oven?

Yes, you can put quartz in an oven, but it depends on the specific type and form of quartz. Natural quartz crystals can withstand high temperatures, but sudden temperature changes can cause them to crack. If you're using quartz in a cooking context, such as quartz countertop materials, be cautious about direct heat exposure, as they may not be designed to handle extreme oven temperatures. Always check the manufacturer's guidelines for safe usage.
