This book does indeed contain what it says on the tin, in that it shows quite a number of surface treatment techniques and a range of effects that you can get with each. One big advantage is that it indicates the archival properties of the techniques, the only such book I've come across that does this. I've so far been a bit reluctant to play with different chemical mixtures (such as soaps and foams) for this reason. A substantial disadvantage of this book is that a lot of the techniques require specific art products from specific manufacturers that may be easily available in the US, but aren't that ubiquitous (nor very cheap!) here. Also, what "fibre paste", "ceramic stucco", "Tyvek" or "Venetian plaster" exactly are is explained nowhere. It may be obvious for US readers, but it's not clear to me. Only some of these things have (American...) suppliers in the resources section. Having said that, there are also techniques using the widely available water, cooking salt, alcohol, etc...! All in all, it's a nice book that may inspire me to experiment with what could possibly be equivalents to these unknown American things. I have used salt, alcohol, etc. in my paintings before, and so it's not all new to me, but for someone who is entirely new to this kind of painting the instructions in the book are maybe a little bit on the short side. On the other hand, keeping the instructions short is probably in keeping with the experimental approach.
