Dataset ID,
Conditions,"100 g, start 10°C, room 22°C, 20 min. Final ≤15°C in EVERY trial; ≤5 tokens; ≤18 mm added thickness. Covered liquid water; cups/lids, mass, starting temperature, duration, exposure and reading procedure match within and across trials. Surroundings stay at the stated room temperature. No ice, phase change, active heating/cooling, direct sunlight or meaningful evaporative cooling. Each trial uses fresh samples. Accuracy is not supplied."
