Jattes are a sort of fire pot, formed from a bowl of wood, around which are fastened five jets, arranged for discharging in alternate sections after the manner of turning suns. The effect of the jets is to cause the bowl to rotate on the surface, and other jets are arranged within the bowl as for the pots a aigrettes. The jet in the middle receives fire from the last section of the turning sun and gives this fire in finishing to the charge, which casts forth the garniture. (PL. VIII, fig. 10.)
Some varieties of this firework are much larger and more complex, with a diameter sometimes as much as 4 feet. These are made by the use of numerous vessels, which do not turn, but only serve to carry the fire pots and a light frame, which is garnished with jets placed in various positions. Fire is kindled only at one point, whence it is communicated to all the parts of the piece.
