Hi Marshall, "High temperatures add increased energy to the particles, thus increasing the chance they will hit each other and aggregate..."
I am aware of this effect, but don't know the optimum temp. I have been running Marx's HVAC machine with start water controlled to 75 F +/- 0.5. No control after start. Occasionally, I have a batch usually in the last 15 minutes of a 2.5 hr. run turn yellow-tan, and no longer completely clear. Can you offer any recommendations regarding start water temperature? I have variables; uncontrolled room temperature and a not-well regulated line-voltage and no water bath to cool the vessel during the process. And, I am not keeping track of the moon phase during generation.

Exposure to light, primarily uv or sunlight. 6. The ph of the CS, upon absorption of CO2 it turns acid, the increased concentration of H+ in the CS causes the particles to NOT repell as well, and thus aggregate. 7 Temperature. High temperatures add increased energy to the particles, thus increasing the chance they will hit each other and aggregate, low temperatures reduce the browning movement, thus allowing increasing concentrations to drift toward the bottom, thus increasing the possibility of aggregation.
