The garlic bulbs were approximately at room temperature when thermocouples #1 to #6 were attached to the surface of individual cloves. Over the course of the first one to two hours they equilibrate with the background temperature as shown. Thermocouples #7 and #8 remained in the freezing chamber and recorded a brief transient warming as the background air was heated slightly from the introduction of a room-temperature garlic bulb. Abrupt jumps in the temperature with a sharp peak indicate a freezing event in the adjacent clove. Overlapping bumps are presumably the result of heat dissipating from a single clove warming adjacent ones.
