A salt shaker is a small container filled with salt that is used to sprinkle salt onto food. Salt shakers were invented in the 19th century. The screw-top salt shaker was invented by John Mason in 1858. Around 1871 when salt became more refined, some ceramic shakers were molded with perforated tops. A good salt shaker should have the following characteristics: 1. The shaker hole should be big enough, but not too big to let out too much salt. 2. The material that the shaker is made out of should not be reactive to sodium chloride (salt). 3. The shaker cap should not come off by accident while shaking. 4. The holes must be designed to prevent salt clogs. 5. Salt shouldn't get stuck in between the head and body of the salt shaker, so that salt doesn't spill when opening the head for a refill. 6. Design the salt shaker head in such a manner that, water if casually dropped on the shaker head doesn't drop in to the shaker and wet the salt. 7. The salt shaker should have a solid grip. 8. Design in such a manner that the shaker is never filled completely with salt (So that there is moving space during a shake). For example, design the shaker to have a narrow neck. That way, while filling, it appears full, when the salt reaches the top, whereas there is some space at the bottom towards the sides. 9. The salt shaker must not be too big or too small. It should be just the right size for the average hand. External links Look up Salt shaker in Wiktionary, the free dictionary.
