What does unmolten mean?
Unmolten means not melted: it describes a substance that has not changed from solid into liquid, particularly after exposure to heat. The word is especially appropriate when heating is implied, as in unmolten metal, while still solid is a broader and more conversational alternative. Unmolten can describe metal, glass, clay, wax, snow, or other substances, though it is less common than unmelted in everyday speech and has a somewhat literary or technical character. Its distinctive use is to emphasize the boundary between a solid substance and its liquid state. The adjective is formed by adding the negative prefix un- to molten, making its meaning transparent and allowing a precise contrast between a substance that remains unmolten and one that has become molten.
