A batch pack for silver filings is employed in the preparation of dental amalgam in a laboratory mixing apparatus. The batch pack comprises a foil bag which can be destroyed by the mixing vibration and a briquette or tablet of silver filings. The density of the briquette of silver filings is not more than about 8 gram per cubic centimeters or a pore volume of about 20 percent of the volume of the briquette.
