Members Dbeeksci Posted March 13, 2019 Members Report Posted March 13, 2019 I'm a restorer looking for information related to the processing and covering of small cases and boxes with thin leather during the 18th and early 19th centuries. I have several early boxes that need to be rebuilt and recovered. These cases were made to hold all sorts of early devices, from medical and scientific instruments to silver items and delicate glass items. They were cased within velvet-lined thin wooden boxes covered with paper-weight stiffened and decoratively-embossed leather. Has anyone read or know of a resource for information on the historic methods of treating leather to make it stiff, yet still pliable enough to be gold emboss. An image below shows a piece of the original 1820s leather removed from the case. I thank you in advance for any assistance. Dale Quote
bermudahwin Posted March 13, 2019 Report Posted March 13, 2019 hi Dale where are you based? I am in the UK and restore 17 / 18 century books amongst other things. But I know some of the stuff I use is Archival (which equals expensive) and not available elsewhere. If its not as rare or valuable and not a book, see photo of binocular case before and after, I have been very successful with judicious use of Dr Jacksons Hide Rejuvenator from Tandy Leather I also use my own mix of beeswax, oil and turpentine, very cautiously. It often darkens the leathers. In bookbinding we repain pieces such as in the picture, from the back first, and often by laying a kitchen towel with the product on it on a flat surface, and laying the flesh side of the leather down first, leave it for a while and check, repeat as needed. We would then build up the leather by cutting and skiving pices to go into the gaps, then dyeing the insets. Quote No longer following it.

Members Dbeeksci Posted March 13, 2019 Author Members Report Posted March 13, 2019 Hi: I'm in central US. Yes, I'm familiar with the varied treatments of old leather and now learning about the drying process of new leathers is priority. The new leather that I'm using .05 thin and too pliable. I have soaked it in cold water and then immersed in 180 degree (F) water for just a minute. It is now drying at room temp. We'll see how it dries; hopefully it is a bit more stiff. I've noted from other's that it's dangerous to apply heat however I may take a test piece and use a hair dryer. Quote

We have treated almost as cuir bouilli on occasion, and put on lowest oven as if for a meringue, but it needs watching and checking Quote No longer following it.
Members YinTx Posted March 13, 2019 Members Report Posted March 13, 2019 Just curious, how do you know that the original leather was stiffened? Was it possibly pliant when new, and stiffened with time? There is a wiki page and other information on the net on restoration of old leather, primarily regarding British Museum leather dressing.

YinTx YinTx: That's a really good point, I don't know for sure however the way the leather has been cut and folded suggest it was not very pliable. Then again, the boxes with domed tops appear to have been covered when the leather was slightly damp in order to conform properly. Hide-glue was used for both the interior velvet and the exterior leather. Boxes where leather was used as a hinge must have used a pliable glue along the hinge area. I'm assuming the gold embossing was the last of the process. Quote

(meant in earnest, nothing less) YinTx Don't you dare shut up, your input on the forum is always on my 'must read' list. @Dbeeksci please could you post pix of the domed cases, as they may be shaped by cutting, rather than raising. I have seen both methods. H Quote No longer following it.
