... combination The combination of elements to give compounds. There are three laws of chemical combination. (1) The law of constant composition states that the proportions of the elements in a compound are always the same, no matter how the compound is made. It is also called the law of constant proportions or definite proportions . (2) The law of multiple proportions states that when two elements A and B combine to form more than one compound, then the masses of B that combine with a fixed mass of A are in simple ratio to one another. For example,...

...Wedgwood on porcelain supports for his paintings, produced prints of a fine-grained texture based on the free use of stipple and engraving tools.

Before the moistened clay had fully hardened, the symbols were inscribed on it with the sharpened point of a reed, resulting in wedge shapes; each wedge or combination of wedges represented a symbol or syllable. The tablets were then fired, like pottery, becoming essentially indestructible. The great majority of texts recovered that use this wedge-shaped, or cuneiform, writing are on clay tablets, but it was adapted for other media, such as...
