Polishing ores

group photo of students
Several types of ores were prepared, and after each participant selected a stone of his/her choice, sandpapers were used to polish stones.
The goal was to create a smooth surface by using finer and finer grit sandpaper, and to create an accessory of their choice.
The work required a lot of patience, but everyone concentrated on the task.
