Small reusable containers with two compartments for storing, transporting and intermixing pre-proportioned substances such as a metallic powder and mercury used in making a dental amalgam, provided with a displaceable disk-shaped partition between the compartments to prevent intermingling of the substances during storage and transportation but which, when displaced by way of a pusher, and with the intermingling of the substances, acts as a pestle in aiding trituration of the substances into the dental amalgam. |
