pencil hardness tester price
The core or lead inside your pencil is actually a mix of finely ground graphite and clay filler. This is what makes your lines, shapes and squiggles. Known as the pencil’s lead, graphite comes in varying degrees of solidity or pencil hardness. The pencil hardness scale is a measure of how hard or soft the lead of your pencil is. The European and American scales are the two most popular hardness scales. The European scale uses B to indicate a softer lead and H to indicate a harder lead across a spectrum.
