So is our Elixir solid or liquid? 🤔
Is water solid or liquid? The answer is, it depends.
Take water, for example. It can be both, yes, and that which determines whether it is one or another is how closely packed the molecules are, and what kind of lattice they form. We may call this "temperature" but there is another variable, which is "pressure". Thus changin temperature or pressure will differentiate whether it is solid, liquid, or gas. We may broadly categorize that thing that is responsible for these changes (temperature / pressure) as "energy" or "fire".
The salts themselves, properly prepared, have energy and fire. That is, due to that fire, they have a capacity to alter what the final form the elixir takes - be it more liquidlike, as in an oil or a thicker oil or even a soft tar, or even a very solid rock or powder. The things being altered (like the water molecules) do not change their natures - what changes is their structures, and that which allows the structural changes is that fire that, in our case, comes from the salt. It is not about the "concentration" of the salt, but about it's energy or energetic forms, and its capacity to pass this energy on.
Just as some salts will naturally pull moisture from the air and want to dissolve themselves into a liquid, and some salts do not do this and would just as well prefer to release the excess moisture and form their own types of crystal lattice, so too do the prepared salts of the spagyric elixir play a role, and the energy or "fire" that transforms the matter first passes through that salt. In that passing through the salt before the fire is transferred to the matter (that mercury and sulfur), it also transforms the salt, and the transformation of the salt transform the matter (mercury / sulfur). That it, it reorganizes the structure such that all three are molecularly joined in a new type of organization / crystal lattice.
Some of these transformations are not easily reversible. For example we can easily melt ice to form water, yes, because the lattice responds to changing temperature, but if our elixir had formed a solid because of changes in energy that are more related to pressure, as we try to change the pressures the phase of the elixir may not change. Some crystal lattice structures, once formed, will resist certain "fires", and transform them or pass them on while maintaining their own homeostasis. For example, piezoelectric crystals, which many crystals (including rock sugar) exhibit.
At this stage, the elixir has a power that is not necessarily only the result of whatever types of medicinal compounds the plants contained from which it came, but rather from the types of novel structures that have been formed. The effects of the elixir are thus not merely concentrating some pre-existing medicinal chemical quality, but transferring on an energetic quality that in created by the elixir itself, just like a piezoelectric crystal can create an "electric current" if it is hit, or can vibrate if one passes electricity through it.
