Sent to Nathan Sawaya, Brick Artist who is behind the ongoing Art of the Brick Exhibition running at The old Truman Brewery, 15 Hanbury St, London E1 6QR to 4th January 2015. We make Mini clay bricks and thought you be interested in giving them a try alongside the Lego bricks? We, at ClayClay, are one of only three manufacturers in the world of Mini Clay bricks. The clay is from North Yorkshire, UK, the bricks are made in the Isle of Wight. They are joined by your own mortar mix - flour, sand and water and come apart if you put the whole artwork in cold water. Sizes are 32*16*10.5mm and 48*24*16mm. If you would like samples pleae contact us or see more at www.clayclay.co.uk or www,minibrick.co.uk . I look forward to hearing from you.
