Clay squares for the drying of melting point test specimens
150 × 150 mm clay platelets in squares of 30 × 30 mm, designed to snap off with ease

Advantages over clay fragments:

No waste, can be put to maximum use.
No pointed or sharp fracture edges.
No risk of cut or prick wounds.
No risk of splinters in your eyes.
No splinters left on work tops and floors, hence no broken glass due to Erlenmeyer flasks being put down too hard on splinter pieces.
Handy square size is easy to fix in place with your fingers.
Enough room available for marking.
