RE: Chemistry Explains : Why "Amethyst" Gemstone Familiar in Ancient Times ?

[jamhuery]

Very good question, and this open my mind to do some research, i will answer with some sense.
indeed it is based on a mythology, but Perviously, i have made a thesis about silica xerogel (dry),
in the manufacture of silica gel, we must burn a material contains SiO2 inside,
after it heating at high temperatures, silica ash reacted with NaOH to obtain sol sodium silicate, then this sol soaked with acid to forms a gel, then the gel dried and silica xerogel has been forming, determination of silica coincides with siloxane formation that serve as toxic gas absorber. Indeed there is no reaction between amethyst and ethanol, but siloxane react with alcohol can to form silanol.

but siloxane react with alcohol can to form silanol.

At room temperature?

Indeed there is no reaction between amethyst and ethanol

With out this, then science can not justify the myth ;)

It also means:

Sometimes, the ancestor's behavior can be answered scientifically, for example, they insert Amethyst gemstones into glass to prevent drunkenness, this can make sense, because the nature of silica can be used as absorber with siloxane cluster (group), so the siloxane can absorb the toxic gas, moisture, etc.

That you can't conclude this. Because the people of yesteryear were not correct, amethyst did not prevent drunkenness.

yes it is, thanks for feedback, it mean my conclusion was wrong, i have to change it now,
