After three days, the temperature was lowererd to 281.15 K. After 3 days at 281.15K, the solution in the well solution was changed to 25% MPD in water. After 1 week, the temperature was changed to 277.15K. The well solution was interchanged to a MPD solution at 30%. and after 8 days it was replaced by a 38% (v/v) MPD solution.
