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.
