The temperature at which a completion brine starts dropping salt back out of solution.
A clear completion brine is a saturated or near saturated salt solution, and it has a temperature below which crystals form. The kit measures the true crystallization temperature by cooling a stirred sample and recording the first crystal to appear and the last crystal to dissolve.
Below that point the fluid blocks screens and chokes, changes density and stops being a known weight. The figure is what decides whether a brine can sit on a cold deck, be pumped through a riser in deep water, or has to be reformulated before it ships.
