303) Potash stone discovered at the Squire's Tavern

303)   Potash stone discovered at the Squire's Tavern  - October 25, 2006
                 The Historical Society volunteer crew took time out from work at the Squire's Tavern to dig up an odd looking stone that was part of the walkway in front of the Tavern.  The smooth stone appeared to be possibly  an abandoned gravestone that had been incorporated into the walk.  Upon removing it and turning it over, it was found instead to be an old potash stone.  The tell tale grooves and runoff notch in the stone told the story.  The first step in making potash would be to fill a bottomless barrel with ashes.  The barrel was placed over the potash stone.  Water was slowly poured in the barrel over the ashes until a brown liquid oozed out the bottom of the barrel and was collected on the stone.  The brown liquid ran down the stone, into the grooves and dripped from the notch into a clay container.  The brown liquid was lye, which could be used in soap making or could be refined further into potash.  Potash was an ingredient used to make glass and ceramics or could be used for fertilizer.  Potash production gave early residents of Barkhamsted another source of income because there was a ready market for the material.

In the photo above, notice the grove around the edge of the stone.  If you look closely you can see the notch at the bottom of the stone (just to the right of the shovel) where the liquid was drawn off.
