A device for use in a dishwashing machine to dispense a water-soluble glass or ceramic composition into the machine over a plurality of dishwashing cycles comprising:
- a) a shaped body (20) made of water-soluble glass or ceramic composition;
- within
- b) a container (10) for holding said shaped body (20) with at least part of its walls (10) having perforations (13, 13′) allowing circulation of the washing liquor into and out of the container, characterized in that the container (10) has a Thermal Shock Reduction Factor (TSRF) of less than 0,9 as measured by the following formula:
- 2 TSRF = 60 - T 1 60 - T 2
- wherein:
- T1 is the temperature of a first shaped body (20) disposed within a container (10) taken after the container (10) is acclimatized to a temperature of 60° C. in an automatic dishwasher and then placed in another automatic dishwasher, running at 25° C., for 45 seconds;
- and
- T2 is the temperature of a second unprotected shaped body (20) taken after exposure to the same conditions as the first shaped body (20).
A device according to any preceding claim, wherein means (15, 16) are provided on the container (10) or connected therewith to fix the container to a pre-determined position within the dishwashing machine.
