If you've taken a scroll through DIYers' social media feeds lately, you've probably seen at least one post where someone reuses thrifted crystal cut glassware or bowls into stunning, homemade candles. And maybe you're thinking about adding a crystal bowl to your thrifting list to try your own. It's unique, it's fun, it's...potentially not safe.

We get it: candles in vintage-style crystal bowls make unique decor, not to mention unforgettable (and affordable) gifts. (Maybe that's why it's one of our top home decor steals to always snag at the thrift store?) And since candles have been poured into all manner of glass containers over the years, why would thrifted crystal bowls be any different? The truth is, candle holders need to withstand the high heat from the flame and melted wax without fracturing. This rules out that spare jam jar and, you guessed it, crystal. Why? Crystal simply isn't made to handle the heat (no pun intended) and can crack from it. Some DIYers warn that thrifted crystal is even more susceptible because it may have cracks or fractures you can't see.

Does this mean you need to completely check vintage-inspired homemade candles off your list? Luckily, no. There are lots of crystal-lookalike containers out there, made specifically for candlemaking, that can give you the same vibe without the risks, like ​DARJEN 10 Pack Green Candle Jars or IWOWHERO Tealight Candle Holder Cover Vintage Glass Jar. No matter which container you choose, always check that it is heat-resistant and crack-free before pouring in hot wax or doing a burn test. 

If you have your heart set on using a thrifted crystal bowl and understand the risks, there is one trick you can try to see if it's heat-safe. Known among candlemakers as the boil test, it's a good way to see if a container can handle the heat. First, use proper safety precautions: wear safety glasses and long sleeves, and conduct the test in a safe, contained area. Then bring a kettleful of water to a boil and pour it over the bowl. The downside of this test? If the bowl isn't heat-safe, it will fracture or break. If you'd rather not risk breaking that beautiful piece, don't worry; there are lots of fun ways to upcycle thrifted glass and crystal into adorable decor.
