Webb4. Slowly add 100% alcohol or acetone and stir the mixture. At least 80% of the total volume of the slurry should consist of dry ice and only 20% of alcohol or acetone. 5. When the slurry nearly stops bubbling, its temperature has fallen to about -70°C, and it is suitable for flash-freezing. Keep adding dry ice as needed to reach this point.
