Zusammenfassung:	A spark plug having a glass seal formed from a first glass material and a second glass material. The first glass material has a glass transition temperature/softening point that is greater than the glass transition temperature/softening point of the second glass material. The first glass material and second glass material form a matrix and when combined with a filler have thermal expansion rates and properties the approximate leaded glass.
