Mineral textural quantification methods have become critical in both geosciences and mineral processing as mineral texture is a critical factor contributing to ore variability. However, the lack of objective mineral texture classification has made quantification difficult.

Most geologist prefer at least 1 m trays or slightly larger. It's because the core is logged in meters and therefore it is logical to assume that 1 meter intervals is better for viewing and loging the core . In Canada we use 5 foot wooden boxes because core is still drilled in feet but logged in meters [5 feet = 1.52 meters].
