Doorknobs are a low-lift way to elevate the style of your home. Just switch out your standard hardware, replace it with a glass beauty and, voila, your door suddenly looks like it belongs in a historic Victorian. However, Reddit user Proteon took to the internet to warn people about the surprising dangers of glass doorknobs after sunlight streamed through theirs and started a house fire. Yikes.

But let's back up: How did this happen? Well, when light is refracted through glass objects, it can become hot enough to start a fire. However, the reason most people aren't aware of this danger is because, while possible, it doesn't happen often. The London Fire Brigade said in 2015 that only 125 light refraction cases had been reported in the last five years - and not all of those fires were the result of doorknobs.

Basically any glass object could cause a blaze, including jars, mirrors, fishbowls and even eyeglasses when left in the sun. In fact, last year, sunlight pierced through a Nutella jar that was left on a windowsill of a couple's home, and it destroyed their roof and caused damage on the first floor of their home.

The bottom line: When the sun's out, your glass should be put away. And when it comes to permanent fixtures, like doorknobs, you might want to reserve them strictly for rooms that don't get a lot of natural light.
