Cambridge Panelled Calf Bindings

Preface..

I am at present creating a medium sized specialist library of purely Cambridge panelled calf bindings for an eminent heart surgeon. Half of the library will consist of important "Chirurgicall" Treatise from the 16thC to the early 19thC the other half will be of a varied topic of 16th - 18thC first editions and topped off with a complete set of 1st edition and 1st issue Dickens uniformly bound in a deluxe style of the period.
Watch this space for more additions of the Cambridge panelled calf bindings as the library starts to take shape....... 8O)

Book Binding and The Cambridge binding

Of all of the different styles of bookbinding throughout the centuries (I practice more than 70 styles) the "panelled" calf is the one I always find aesthetically pleasing.

Supposedly started in Cambridge University in the early 17th Century it soon became their trademark style with simple line tooling around a middle and darkened centre panel and a lightly speckled middle panel this style is timeless if executed in the proper manner.

 

Creative book binders combine various ornamental tools to achieve numerous variations in book decoration. Bindings can be dated by the type of ornamentation used, with rococo ornaments common in the seventeenth century and classical Greek key borders popular for eighteenth century bindings. In some cases, individual binders ( like myself ) or workshops are recognizable by their distinctive tools and craftsmanship.

Book binding and Colouring books

It can be very difficult to match the colours of the period as most of them were chemically applied, the book would be bound in a natural calf and then paste washed to prevent the chemicals penetrating the skin.

 

The skin is then washed with picric acid, a highly volatile compound that gives an even yellow reflective colour, this is changed to a medium tan by washing with "salts of tartar" (potassium tartrate).

Although I still practice the chemical applications a much safer method I use is by fermenting vegetables and vegetation extracting the pectins, colour and tannin, the spice turmeric is virtually the same yellow as picric acid, oak bark gives a mellow brown, horse chestnut is much darker, crushed green walnuts or ferrous sulphate for black, Brazil dust, woad, earth boles and pigments, cochineal , cherries, beets, more like a shopping list really. I've even boiled mahogany chippings and extracted the most amazing colour.

To begin this style of book binding the book is flexibly sewn on raised cords with laced-in boards which are splayed out and secured within.    

The book is then bound in a natural vegetable tanned calf, the dyes having been strained and prepared earlier, the edges and spine are coloured before turning in. I usually "cap" the edges of the book before colouring, to prevent any accidental splashes marking the edges.

After applying the colours I make a "tallow" compound of bulls fat and candle wax and coat the whole of the book, this prevents the hot tool from scorching the surface of the skin by cooling it slightly, it also acts to burnish and blacken the impression the tool leaves behind.

Book binding and Cambridge Panelled Calf Bindings

The blind tooling comprises of small hand tools and fillet rolls (decorative wheels) creating a perfect (well almost) symmetrical pattern resulting in an authentic contemporary design.

 

     

The edges of the boards and the inside edges are also blind tooled before the end papers are pasted down. The tallow is removed and the book is polished with a hot iron and prepared for gilding. The spine of a Bible this size will take up to 1000 impressions of tools in gold leaf.

Book binding and Cambridge Panelled Calf Bindings

Through every period of book binding since the early 1600's the Cambridge panelled calf has been one style of book binding that has always retained an air of quality and craftsmanship whether they are single large folios, multiple volumes in folio, quartos, octavos on whatever subject.

The versatility of the Cambridge panelled calf is such that the tooling may look similar or even the same until you match two different volumes together and find either complete differences or a subtle variation of the same tooling.
Large family Bibles, historical books, theology, natural history, every subject printed on a quality paper has been embraced by this quality style of book binding.

Folios Quartos and Octavos in different depths of browns, reds and blacks, some speckled some not, but all looking and feeling quite authentic in their new bindings.
