I see (off topic a bit ) - But there is a hidden truth the CRT TV's . must make money some how so either they sell for excess of .2 or can sell it else were for under .2 The metal inside CRT and TV's add up and some have a nice chunk of steel
Treatment of lead glass
Hot solution of the sodium salt of ethylenediaminetetraacetic acid (EDTA) was shown to remove lead from the glass surface. A mechanism is proposed whereby lead is removed by a two-step reaction involving hydroxyl ions and EDTA. The rate constant and the overall heat of activation were estimated for this reaction. Potassium and silicon are also removed from the glass surface and show a dependence similar to that of lead removal. Potassium and silicon, however, do not form complexes with EDTA. Thus, it appears that lead removal weakens the silicate structure of the glass surface, allowing the potassium and silicon to be attacked and removed by hydroxyl ions and/or water. Experimental results indicate that the silicon released from the glass surface is in the form of silica.
Is there a dirty secret about the lead glass . Some countries are unregulated I could see them using that typ of glass with out a thought as it's been shown toys have come to America with lead paint . So does any one think it is crushed and then recycled in to cement for roads or buildings or windows mirrors that no body is the wiser.
