    Has anyone compared the green glass that is used for ornamental
    objects in Mexico to what is supposed to be "Helenite". I remember
    back when Helenite was first available someone compared it to green
    glass, a=nd I believe it is glass. 

    google "In general, volcanic ash is mostly silicon,aluminum,
    magnesium, iron a specific volcano in mind, there maybe a major
    chemcial analysis, and less likely minor chemical analysis." 

    Common glass is made from:
    sand or silica (SiO2)
    sodium carbonate (Na2CO3)
    limestone (CaCO3)
    magnesium carbonate (MgCO3)

    additives to improve the glass quality and to colour the glass.
