Claim:
1. A method of protecting a workpiece comprising: forming a low T arranging a workpiece to be protected between the first substrate and a second substrate where the sealing layer is in contact with the second substrate; locally heating the glass sealing layer with laser radiation to a sealing temperature sufficient to melt the sealing layer; and inducing transient absorption of the laser radiation by the first substrate to melt at least a portion of the first substrate and form a glass seal between the first and second substrates, wherein the first substrate is a glass substrate having (a) an absorption of the laser radiation that is less than 15% at room temperature and (b) an induced transient absorption of the laser radiation that is greater than 15% at the sealing temperature.
