Paste Wafer Seals - Victorian era letter sealing

[jbb]

I found a box of Victorian era paste, wafer seals! They were made of flour, water and pigments, dried into discs, and used to seal letters before the ultra-modern invention of gummed envelopes. You'd wet them and press them between the flaps of your letters. Often a waffle-pattern seal was used to press them together.

Anybody have more information?
