En quelques images, voici notre proc\u00e9d\u00e9 pour fabriquer des \u00e9tuis en cuir dit bouilli<\/em>. Nous avons pris en exemple un mod\u00e8le tr\u00e8s connu datant du d\u00e9but du 15\u00e8me si\u00e8cle, expos\u00e9 au mus\u00e9e de Cluny.
\nLe peu d’outils n\u00e9cessaires : un tranchet (couteau tr\u00e8s fin et tr\u00e8s coupant), une grande pierre dure et parfaitement plane, quelques baguettes taill\u00e9es dans de l’os, une forme en bois et une rappe.<\/p>\n

In some pictures, here is our process to make boiled<\/em> leather cases.<\/span> We took as an example a well-known model dating from the beginning of the 15th century, exhibited at the Cluny museum in Paris.<\/span><\/span><\/p>\n

The few tools needed : a slicing knife (very thin and very sharp knife), a large hard and perfectly flat stone, some chopsticks carved in bone, a wooden form and a file.<\/span><\/span><\/p>\n

\"\"<\/p>\n

Le cuir utilis\u00e9 est du veau tann\u00e9 \u00e0 l’aide de v\u00e9g\u00e9taux d’une \u00e9paisseur de 8\/10\u00e8me de mm, ce cuir est souple et sa fleur est\u00a0 lisse :<\/p>\n

The leather used is calf skin vegetable tanned of a thickness of 8\/10 th of mm, this leather is supple and its grain is smooth :<\/span><\/span><\/span><\/p>\n

\"\"<\/p>\n

Pour la colle, nous avons utilis\u00e9\u00a0de la colle fabriqu\u00e9e \u00e0 base de cartilages de porc : la colle forte. De nos jours, cette colle n’est plus disponible sous ce nom mais on peut en trouver au supermarch\u00e9 tout simplement au rayon p\u00e2tisserie, en effet la g\u00e9latine pour faire des g\u00e2teaux est de la colle forte.<\/p>\n

J’ai essay\u00e9 d’autres colles animales : nerf, os, peau … Mais, d’apr\u00e8s mes quelques exp\u00e9riences, rien n’\u00e9gale la colle de g\u00e9latine \u00e0 part l’hictyocolle<\/strong> (colle de vessie natatoire d’esturgeon). Cette mati\u00e8re animale se trouve toujours dans le commerce comme fourniture pour l’art de la reliure. Toutefois, pour ne pas encourager la p\u00e8che de ce poisson devenu rare et maintenant heureusement prot\u00e9g\u00e9, je pr\u00e9f\u00e8re\u00a0 utiliser de la simple g\u00e9latine pour g\u00e2teaux.<\/p>\n

For the glue, we used glue made from pork cartilage : the strong glue. Nowadays, this glue is no longer available under this name but can be found at the supermarket just pastry department, indeed the gelatin to make cakes is strong glue.<\/span><\/p>\n

I tried other animal glues : nerve, bone, skin… But, according to my few experiments, nothing matches the gelatin glue except the hictyocolle (swim bladder sturgeon<\/span><\/span>). This animal material is still commercially available as a supply for the art of bookbinding. However, not to encourage the fishing of this rare and now fortunately protected fish, I prefer to use simple gelatin for cakes.<\/span><\/span><\/span><\/p>\n

Passons \u00e0 la pratique :
\nPr\u00e9paration de la colle forte de g\u00e9latine : Dans un pot (\u00e0 confiture), mettre quelques feuilles de g\u00e9latine (au besoin les casser) puis ajouter l’eau froide pour couvrir \u00e0 hauteur. Une fois les feuilles bien ramollies, faire chauffer doucement le pot au bain-marie en remuant. A partir de 23 \u00b0C, les fibres de collag\u00e8ne de la g\u00e9latine se s\u00e9parent les unes des autres et on obtient un liquide homog\u00e8ne et transparent. En contr\u00f4lant la temp\u00e9rature avec un thermom\u00e8tre,\u00a0 il est maintenant possible de tremper le cuir dans cette colle.<\/p>\n

Let’s move on to practice : Preparation of the strong gelatin glue: In a jar (jam), put 2 sheets of gelatine (if necessary break them) then add the cold water to cover at height. Once the leaves are well softened<\/span><\/span>, gently heat the pot in a bain-marie stirring. From 23 \u00b0 C., the collagen fibers of the gelatin separate from one another and a homogeneous and transparent liquid is obtained. By controlling the temperature with a thermometer, it is now possible to soak the leather in this glue.<\/span><\/p>\n

\"\"<\/p>\n

Un d\u00e9gagement de bulles est visible, accompagn\u00e9 d’un bruit d’\u00e9bullition. En quelques secondes, le cuir fin est totalement impr\u00e9gn\u00e9 du liquide, il est flasque et gluant.<\/p>\n

A bubbling is visible, along with a boiling noise.<\/span> In a few seconds, the fine leather is completely impregnated with liquid, it is flaccid and sticky.<\/span><\/span><\/p>\n

Remarque : Il est plausible que de cette \u00e9tape o\u00f9 les bulles d’air s’\u00e9chappent vienne l’appellation cuir bouilli<\/strong>. Cela ressemble tout \u00e0 fait \u00e0 une \u00e9bullition mais la temp\u00e9rature du liquide employ\u00e9 est bien en dessous de 40 \u00b0C.<\/p>\n

Note <\/strong>: It is plausible that from this stage where the air bubbles escape come the boiled leather name.<\/span> This is very similar to boiling, but the temperature of the liquid used is well below 40 \u00b0 C.<\/span><\/span><\/p>\n

Remarque : \u00a0Lors du trempage du cuir la temp\u00e9rature de la colle ne doit pas d\u00e9passer 37 \u00b0C sous peine d’ab\u00eemer d\u00e9finitivement la structure du cuir. Une temp\u00e9rature de 32 \u00b0C est optimum, plus froid \u00a0le liquide p\u00e9n\u00e8tre plus lentement dans le cuir mais cela n’est pas un probl\u00e8me.<\/strong><\/p>\n

Note : When soaking the leather, the temperature of the glue should not exceed 37 \u00b0 C, otherwise the structure of the leather will be damaged.<\/span> A temperature of 27 \u00b0 C is optimum, colder the liquid penetrates more slowly in the leather but this is not a problem.<\/span><\/p>\n

Ensuite le bout de cuir est plac\u00e9 sur la pierre et par\u00e9 \u00e0 l’aide du tranchet :<\/p>\n

Then the piece of leather is placed on the stone and trimmed with the tranchet :<\/span><\/p>\n

\"\"<\/p>\n

Le parage est indispensable pour ne pas faire de \u00ab\u00a0marches\u00a0\u00bb sur les raccords, ce qui serait disgracieux et fragile.
\nAid\u00e9 de la colle gluante, le cuir adh\u00e8re \u00e0 la pierre et facilite ce travail tr\u00e8s d\u00e9licat.<\/p>\n

Trimming is essential to not make \u00ab\u00a0steps\u00a0\u00bb on the fittings, which would be unsightly and fragile.<\/span>
\nAided glue sticky, the leather adheres to the stone and facilitates this very delicate work.<\/span><\/span><\/p>\n

Remarque : La surface du cuir est utilis\u00e9e au maximum, les ch\u00fbtes de cuir sont minimes, il reste seulement\u00a0 quelques fins copeaux. Il est tout \u00e0 fait possible de parer le cuir avant de le tremper dans la colle.<\/strong><\/p>\n

Note : The leather surface is used to the maximum, the leather falls are minimal, there are only a few fine chips left.<\/span> It is quite possible to trim the leather before dipping it into the glue.<\/span><\/p>\n

Le cuir est dispos\u00e9 sur la forme, les jointures sont fix\u00e9es avec un b\u00e2tonnet en os :<\/p>\n

The leather is arranged on the shape, the joints are fixed with a bone stick :<\/span><\/span><\/p>\n

\"\"<\/p>\n

Les jointures sont liss\u00e9es :<\/p>\n

The joins are smoothed:<\/span><\/span><\/p>\n

\"\"<\/p>\n

Les rectangles de cuir \u00e9pais maintiennent les passants en forme.<\/p>\n

Thick leather rectangles keep passers-by in shape.<\/span><\/span><\/p>\n

Il ne reste plus qu’\u00e0 d\u00e9corer l’objet avant qu’il ne soit compl\u00e8tement sec :<\/p>\n

It remains only to decorate the object before it is completely dry :<\/span><\/span><\/p>\n

\"\"<\/p>\n

Les motifs sont incis\u00e9s avec un fine lame, le fond est \u00ab\u00a0repouss\u00e9\u00a0\u00bb en utilisant un outil en os fait maison. Une fois sec, l’objet est huil\u00e9 avec un m\u00e9lange d’huile de lin et de cire.<\/p>\n

The patterns are incised with a thin blade, the bottom is \u00ab\u00a0repulsed\u00a0\u00bb using a homemade bone tool.<\/span> Once dry, the object is oiled with a mixture of linseed oil and wax.<\/span><\/span><\/p>\n

Remarque : On peut dire que cette bo\u00eete est enti\u00e8rement fa\u00eete de collag\u00e8ne,en effet le mot collag\u00e8ne<\/em> vient de termes grecs signifiant \u00ab\u00a0qui fait la colle\u00a0\u00bb<\/em> or le cuir lui-m\u00eame est constitu\u00e9 de cette substance. L’ajout de collag\u00e8ne augmente la densit\u00e9 du cuir (l’air chass\u00e9 est remplac\u00e9 par la colle et les fibres du cuir sont renforc\u00e9es).<\/strong><\/p>\n

Note : It can be said that this box is entirely made of collagen, indeed the word collagen comes from Greek terms meaning \u00ab\u00a0who makes the glue\u00a0\u00bb or the leather itself is made of this substance.<\/span> The addition of collagen increases the density of the leather (the hunted air is replaced by the glue and the fibers of the leather are reinforced).<\/span><\/span><\/p>\n

R\u00e9sultat final :
\nLe couvercle s’embo\u00eete, il est parfaitement ajust\u00e9.<\/p>\n

Final result :
\nThe lid fits, it is perfectly adjusted.<\/span><\/span><\/p>\n
