The salt box was full of meaning, over and above its practical importance. It was a symbol of hospitality in Germany, and suggested a well-run and comfortable home in Britain and Ireland too. Like salt itself the box might not be noticeable, and yet it was essential for cooking.

Salt boxes could be covered with decorative carving, sometimes as an engagement gift, painted, veneered, or left plain. Antique boxes that look simple may be very well crafted.
