Two identical supports of stainless steel, grade18/10 were used in the test.
The resonator ISTOK® -R (support for the sample N?1) was processed according to the technology ISTOK.
The second support for the sample Nº 2 stayed unchanced. Exterior is the same. Identical glass vessels with saturated solution of table salt were put on the supports.
The samples 1 and 2 together with the supports were placed 1 meter away and left for evaporation in the same natural conditions: temperature, humidity, illumination.

The first photos were made after 44 hours after the beginning of the test.

Sample Nº1                                                        Sample Nº2

In the sample Nº 1 the crystallization only takes shape along the edges
In the sample Nº2 the crystallization has coursed more intensively, but crystals are still in the solution.

Photos after 89 hours.

sample № 1                                               sample № 2

In the sample  Nº 1 the crystallization is still occurring.
Sample № Nº2 is absolutely dry – the crystallization is completed.
The  speed of the crystallization of the solution, being left on the resonator, significantly courses slower, than in the check sample.
