On Wednesday, we visited the Guinness Storehouse in Dublin and followed a self-guided tour and learned loads about the making of this special brew which had its beginnings in 1759 when Arthur Guinness signed a lease on the St. Jame's Gate Brewery for a period of 9,000 years.
At one level of the tour, there were scads of bottles, cans and other forms of advertisement from the early years. On one shelf, I found a display of stoneware bottles from the 1890s. The last bottle is one I picked from a shelf in Johnnie Fox's Pub in the Dublin Mountains to take a picture. It has no markings or label, so I'm not sure of its origin. It's just a lovely bottle.
The second bottle is glazed in a similar fashion to many old jugs and crocks you see in Ireland inside the pubs. I'm not sure what kind of glazes these are. The jug at the end (from Johnnie Fox's) is glazed similarly.
