How to use a refractometer for beginners / quick Gemology tutorial
This is a refractometer, one of the key tools in gemology. It uses light, a polarising filter, and a tiny drop of refractive liquid to measure how light bends inside a gem.

Welcome to the series where I test puck prep tools with a refractometer. Today was all about puck screens. Thin screens ( 0.2 mm ) gave a small bump.

What should I test next? #espresso #homebarista #puckscreen #coffeetools #coffee
