Vintage silver Church Asperger or incense burner. I am not quite sure which but it can be used for either or.
Asperging is a form of ritual purification involving the sprinkling of liquid on the item, person or area to be purified. Asperging is generally done with water that has been sanctified in some way. Usually used in church this can also be adapted to any sort of spiritual practice.
In Hellenic tradition, it is usually sanctified by dropping or dipping a burning bay laurel leaf into the water so that the flame is extinguished. Some traditions bless the water by sprinkling salt into it and declaring it like the sea, the “womb of the Earth”. Herbs or oils may be added or moon water may be used.
The water may be poured, sprinkled using the hands, or sprinkled using an herb that has been dipped into the water for that purpose.
