I have some clear quartz, some rose quartz, some amethyst, and some colored glass bottles that I want to put in my tank... I am worried about the stones more than the glass, because I have heard many people put glass bottles in their tanks just as long as I boil the labels off. Has anyone ever put crystals in their tank before? I know not to put things like geodes in with limestone on them, but everything seems pure except the amethyst which has some sort of black stone left from which it grew off of... and has some veins of the same stuff... Could I just sand it off with a dremel tool?
By chemicals... umm... you mean elements or compounds? Basically Quartz is a lattice of SiO2 molecules, which form tetrahedra of a Silicon bordered by four oxygens. Although there is only two oxygen in its chemical formula, the tetahedra overlap molecules to make it four.
just one: silicon dioxide (SiO2) which just happens to be quartz. There are many varieties of quartz, which can have chemical impurities. Amythest and Citrine quartz have traces of Iron oxide. Rose quartz has traces of Manganese and or titanium. Milky quartz has tiny gas bubbles in it. Rutilated quartz has small amounts of the mineral rutile (titanium oxide) in it.
