Hi Steve, Boiling water warps CDs....but you must have meant DC.
All I know about the subject is that the fellow who built the machine recommends about 75-80 for optimal production of particles. Generally, reactions of any type occur faster at higher temperatures. After all, temp is the vibratory rate of the substance. Speaking very simply, I think. Anytime you can control one variable, you know the changes are coming from others. In that sense, having the same start temp will be beneficial with any voltage or frequency. How it will change particle size and yield has not yet been published. When I made LVDC the cloud formed denser faster when the temperature was higher. My guess is that boiling the water will change its chemistry, a big pot of boiling water is dangerous, it is an additional energy use in the production of the silver and since it can be done without it, why bother. I use 80F. I try to keep it the same, within about a half a degree so that I will know that variations are caused by other factors. I am using a Taylor glass thermometer which is supposed to be accurate to about one tenth of a degree, but the resolution is not much better than a half a degree. Incidentally, do you know what happens when you put a cool thermometer in a warm liquid? The stuff in the thermometer expands, right? Wrong. The glass expands; the column drops slightly, initially.

The warm water bath is a pain but so is the long cooking times of my DC setup! I do want to get into HVAC but I'm getting my feet wet with DC. : ) Your comment above about there being a downside to heat. . . Do we have any quantification of this? In other words. . . what would happen if I went ahead and kept the water at boiling or just below? Is there any evidence that this hurts or help the CD process? many thanx!
