Antique pair Imari Oil Lamps vase Asian Japanese brenner kosmos burner

One is missing the glass.  My guess is that these were Vases converted into oil lamps but could be wrong

Knobs on the lamps indicate brenner kosmos

vases are approx 12 inches from bottom to the top round edge  not including the burner which is another 1.25 inches.  The total height of the one with the glass is 20 inches
