By varying conditions such as inkjet resolution, microwave conditions and types of substrate, other crystal morphologies were achieved including hexagonal plate 922 (shown in FIG. 10 c), needle-like eye-shaped crystals 1022 (shown in FIG. 10 d), dense branching crystals 1122 (shown in FIG. 10 e), tree-like dendritic crystals 1222 (shown in FIG. 10 f) and long fiber crystals 1322 (shown in FIG. 10
