Pewter has a low melting point, around 170–230 °C (338–446 °F), depending on the exact mixture of metals. [2] [3] The word pewter is possibly a variation of "spelter", a term for zinc alloys (originally a colloquial name for zinc). [4]

Pure anhydrous caffeine is a bitter-tasting, white, odorless powder with a melting point of 235–238 °C. [7] [8] Caffeine is moderately soluble in water at room temperature (2 g/100 mL), but quickly soluble in boiling water (66 g/100 mL). [197] It is also moderately soluble in ethanol (1.5 g/100 mL). [197]

The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa.
