Dear Jan,

 I was one of reviewers of Rajlich´s hypothesis. According to my opinion, the hypothesis has a strong physical background.

Hi Pavel, it would be nice to try to 1) make some models like what has happened inside quartz and 2) make a detailed study of quartz samples. What do you think?

In the first option, according to my opinion the most important is the behavior of quartz during cavity implosions vs. 'waves freezing'. If we observe nice sets of wavy structures made of cavities, the amount of implosions was huge. And that amount should distrupt the quartz structure, you can imagine many internal structural collisions of quartz creating localized shock waves. According to what is to be found in the samples, it seems that the cavities have well defined shapes like spheres or negative crystals. The cavities are of the same size and distributed in the same planes. The matter had to stop its behavior like a fluid 'immediately' with a various pressure distribution. This distribution had to influence the spaces where the quartz was disrupted, it means that the creation of denser quartz was prefered in the regions of higher pressure. So first, a detailed study has to be done. We need to search for any signs of the structural disruptions of the samples with hypothetical cavitation lamellae and + what do the disruptions look like on atomic-scale levels, which is in practice impossible with today's technology.

Dear Jan,

our scientists in ICP AS made the similar test for chocolate (as you see for quarz). Here are results: http://www.icpf.cas.cz/en/node/978

It means that the cavities are created in the planes of anti-nodes of standing waves, and, opposite, the denser quarz was created in the regions in between, where is higher pressure from both sides of anti-nodes and no movement.

Dear Pavel,

it seems very interesting, but the standing waves are not the case of Rajlich's Hypothesis I think. The waves should travel through the medium, so the cavities in fact travelled through the minerals like a ship travels through sea.

Dear Jan,

the case of microwave tube is the static solution. Petr Rajlich prefered thy dynamical one, but the reality could be everywhere in between. The consequences are the same - the cavities (and/or chocolade melting and evaporation) are in the areas of expansion and the denser quarz is in the areas of compression.
