Agree that it isn't a smelting box in that the name means a box to smelt metals.
I have quite a few of these ornamental boxes that were my mothers (also in TX). They were pretty prevalent in the 1970's and 1980's and many were imported for ornamental purposes. They are designed after ornamental tea boxes and some, like yours, contained smaller containers that hold the teas and condiments.
Are there any markings?
