Hey, I heard that a 5mm quartz lens can ignite tinder in a pinch. Do you think that holds up, or is it just another overblown survival myth?
VioletRook VioletRook
If the quartz is perfectly polished and you have a clean line of sight, a 5 mm lens can focus sunlight enough to ignite a dry tinder, but only under ideal conditions—no dust, precise angle, and a truly dry ember. In the real world you’d be better off with a 10 mm or larger lens; it’s more reliable. So the myth isn’t completely false, but it’s certainly overblown for most survival situations.

Sounds about right—pretty much a textbook “if you could line up a laser, you’d have a fire.” In practice a 5mm glass is a nice trick for a campfire demo, but in the woods your only hope is a bigger lens or a good piece of foil. So yeah, it’s not a myth, but it’s not the best survival hack either.

So you’re basically saying it’s a “nice trick” if you’re in a controlled environment, but in the real world it’s a marginal benefit at best. I’ll stick to a multi‑tool fire starter and keep the quartz in the drawer with my other “just‑in‑case” gadgets.

Good plan. A multitool’s got the fire‑starter plus the backup tools you need, and the quartz is a nice extra if you can actually line it up. Just remember it’s only a real edge when the sun’s clear and your tinder’s as dry as a desert road. Keep it handy, but don’t expect a miracle.

Nice, I’ll file that under “just‑in‑case” and keep it in the drawer with the other oddities. Sun clear, tinder dry, angle perfect—otherwise it’s a nice trick, not a game‑changer.

Sounds like a solid “just‑in‑case” list—just keep the flashlight ready too. If the sun’s out, tinder’s dry, you’ve got the angle, you can win; otherwise, let the multitool do the heavy lifting.

Flashlight is a good backup, but don't expect the quartz to become your best friend in the wild. If the sun cooperates, fine; if not, the multitool does the heavy lifting.

Right, the flashlight’s the real MVP in most scenarios, and the quartz is just a “when the stars align” piece of kit. Stay practical and keep the multitool at the ready.

All right, flashlight logs saved, quartz on the shelf as an optional experiment. Stay practical.
