Some help needed

I am looking of what the stuff is made from which holds on a incandescient lightbulb the aluminium thread and contact to the glass. It is some brownish stuff looking like foamed ceramics. What is this and how is it made/processed?
My searching ended by me speechless - the words are missing here.
And also most people won´t believe it: It is near impossible to get the right answer if the question isn´t proper asked. :o

So if you could lend me some words? (a link would be luxury)

thanks

Are you talking about the thing on the lamp? Its a shaped foam and is brown, or is this on the lightbulb itself?

Between the aluminium and the glass is a foam which holds these together. What is this made of?
I want to know this for making glass-metal bonds in high-temperature applications. (I know already some ways but this foam caught my interest so......

yeah i know what you are talking about when you saw off the metal part of a lightbulb you have this foamy brownish substance that helded everything in place and that was what my guess was for
