The digital display of the "Mini Temperature Controller" pictured above is measured in tenths of a degree centigrade.

•Resolution: 0.1 °C (-40 ~ 99.9 °C), 1 °C (100 ~ 120 °C)

Moore lowered the temperature of the bath by exactly the same increments starting at 40º Centigrade. One tenth of a degree the first day and so on until a perfect crystal formed. The low cost "Mini Temperature Controller" does everything Moore's patented apparatus did nearly a hundred years ago. Coupled with pure "Rochelle Salts", it should be possible to grow perfect crystals this way. This process takes a period of months. Every time the temperature is lowered, the solubility increases and the left out material solidifies. The temperature drop can speed up as the crystal builds.

The graph above shows that 100ml of water holds 200 grams of "Rochelle Salt" at 40º centigrade. At 33º centigrade it only holds 150 grams. So that means a 50 gram crystal has formed during the 7º drop in temperature. There's really nothing to it!

The important thing to understand is that this process results in one solid crystal, not a pile of shards.

Small ones light barbecue fires, what kind of spark would a two kilo brick generate? A mass-pressure to output in watts formula might allow an extrapolation. I'm envisioning two kilo crystals and thousands of pounds of pressure!

That's what I'm asking, what data are you relying on for the extrapolation? A small one doesn't light a barbecue, the spark ignites the gas, same as a flint. I think you need to find something somewhere that shows what amount of power "two kilo crystals and thousands of pounds of pressure" could produce.


Still like the enthusiasm, just not seeing what it's based on.

@Tak22,

I can't answer your question at this time. I wonder about it just like you. However, I believe that it's possible to generate sufficient power with enough large crystals to throw the switch on a set of EPM Chucks, thereby achieving "Perpetual Motion".

2 Kg of pure "Rochelle Salt" added to 2 liters of distilled water would grow a perfect crystal as large as the one those two guys are holding in the picture below, with the help of a $15.99 "Temperature Controller" like the "Inkbird" pictured on top below. (.1 C scale too.)

Another important point; The water volume of the "Mother Liquor" needs to be maintained at the same level so only the heat reduction is controlling the increase in solubility. Allowing the water level to drop even a little would cause the crystal to grow too fast and crack. A "Toilet style" float valve replenishment system to maintain the "Mother Liquor" level would help as a finishing touch.

The float is out. It would accumulate crystal deposits. Below is a water level "Laser Sensor" suspended above and outside the tank:

The replenishment reservoir would need to be gravity fed distilled water like the start up batch. You could probably do it by hand, but one missed day would result in a crack. Moore has the "Mother Liquor Crock" tightly sealed. The sealed Crock more than likely leaked anyway, that's probably why Moore's crystals cracked before they got any larger then Nicholson's, who used the evaporation process. Maybe a combination of seal and replenishment would work best.

Here are three inexpensive items to complement the "Temperature Controller": One; A 1.5 quart Pyrex double boiler. Around $18.00 from eBay. Two; A 12 volt ceramic heating element and, Three; A 12 volt CPU cooler and pump. We have to seal the lid on the Pyrex Crock with silicon, and include a 120 to 12 volt wall transfomer. We can grow a large perfect crystal with these components for under $100.00. This is enough to lower the "Rochelle Salt" solubility down to 50 grams per 100 milliliters. This Pyrex Crock could grow a perfect 400 gram crystal. A crystal this size should be large enough to clamp between the jaws of a "Magnet chuck".

We could focus a Laser at the "Mother Liquor" level and try and drip distilled water into the Crock with an eyedropper, through a pre-positioned pipette, to insure a constant volume over the months required to grow the perfect crystal to full size.
