Islay clay

There’s a bit of received wisdom that was shared with me amongst the ceramic community – there’s no clay on the Scottish inner or outer isles. I have followed other ceramicists working in Scotland, mostly experimenting with hand collected glaze ingredients added to stoneware and porcelain clay bodies, but then something prompted me to push a line of investigation further…..

A conversation with some friends of my son drifted to my project with pints and my local pub, and then onto other possibilities and the subject of whiskey. I went on-line to investigate, and searched using Islay – the source of some of my favourite whiskeys and ‘clay’….. and hey presto, a site focusing on Scottish Back and Tile works over the centuries ( https://www.scottishbrickhistory.co.uk/foreland-brick-and-tile-works-isle-of-islay/ ) brought up a link to a site that produced bricks and tiles, mostly for agricultural drainage, in the 1840s. I was hooked.

I arranged to visit the site in April of this year, helped with advice from various phone calls and email exchanges – particularly from the Islay Natural Heritage Trust. I found the site using the grid references given on the site mentioned above, and the clay pits highlighted on the 1840s edition of the OS map. I took a few small bags as samples, and later that week came back to the workshop to experiment.

The clay is sandy, and silty. It’s like throwing mud. But taking it through a 30, 60 or 100 sieve makes in workable – just, and adding 20% of my hand dug Clee Hill clay helps. The real advantage is that it fires to stoneware temperatures – hence the glaze tests – which is very exciting.
