Coloured enamel powders are then placed into the cells and, once red, the colours turn to liquid and ll the required areas. Cloisonné enamel work is an ancient technique, perhaps most synonymous with Japan. From the photograph, your vases look to me to be later 20th- century and most likely souvenir or export wares, hence the horseshoe mark on the base. At auction, I would suggest an estimate of £15–£ 20.
