RE: Mohs hardness of Norlite
The properties of the particles are different. Some of the larger particles have great compressive strength (but can be brittle)and many of the smaller particles are actually pieces of a perfect sphere that are due to the manufacturing and handling process.
Often, this type of lightweight is referred to as "coated", referring to the ideal pristine larger particles that may have the "coated" appearance due to the surface appearance from the firing/expanding process.
It is very unusually to see 100% lightweight because of the sizes and shapes, so blending to get a desired gradation is necessary in most used.
