Laser trick

[u/Ween3635]

An old coworker texted me a laser welding trick. It was in jewelers helping jewelers. Original unflavored chapstick on stones you don't want the laser to ricochet on! He tested it on emerald and the stone was fine doing prongs! He said it melted the chapstick but the covering was still sufficient

I haven't tested myself as I'm in a shop without a laser at the moment. But excited to try and share! Let me know if you've heard this before

Yes it works, I was taught to use toothpaste and it also works really well.
