I own a glass table with metallic lower part (legs etc). The top glass
plate is attached to the four metal rings with some powerful
transparent glue. Therefore, when you're watching the table you can
actually see these metal rings and the table's lower metal parts
through the top glass plate.

I badly need to remove the top glass plate, but don't know how to
dissolve this glue. Does anyone know which glue is usually used for
this purpose and what can be used to dissolve it?

I tried acetone, but it doesn't have any effect.

Thanks in advace!
