This is the authoritative book on the subject (and you won't find many!). It's a beautifully produced book of the highest quality, very fully illustrated, printed on excellent paper and firmly bound and presented. Kelly covers all of the major Scottish pottery firms in most cases quite briefly - a page or two - though he deals with such as J. and M.P. Bell and one or two of the Kirkcaldy potteries at greater length. So as far as individual potteries go, this is just an introduction, but the book is comprehensive and provides an excellent vehicle for comparison, particularly in the very fine photographs. In the end, it is a great pleasure to leaf through and visually it is stunning.
