Original Santos Vacuum coffee maker. 1 litre coffee pot for 2-8 cups. Size scoop - cap to seal off - spring - lid. Stand to place top sphere on. Sieve. Spare sphere with spring. Height spheres 28 cm. Suitable for coarse grind. It works as follows: fill lower bulb with water, upper bulb with spring with coffee, place lid on it. Put it on the iron rest and then heat up with a spiritus burner (is not included). As soon as the water boils it goes up, top bubbles for a bit and then the coffee goes down without the grind. Upper sphere can be placed on holder. The quick way is to put the bulbs on a hot plate on the gas as soon as the water boils, on the iron rest, with a tea light. Very nice to make coffee in this way while sitting at the table.
