Thread: Hot Pressed Horn Repair?

Plus many times over for being cautious with steam. I know a fella who's brother was a steam fitter. and yes, I am using the past tense. what a horrible way to go.

Let us never ignore safety in our pursuit of knowledge!

Originally, the horn (when rendered soft by boiling) was put into a cast iron mould that both shaped and impressed a pattern (if required) into the horn. For just one pair of scales a three piece mould was used: top and bottom plate and shaper plate, the top and bottom having lugs to enable the mould to be tightly bolted together.

The whole mould was heated to a high temp., and heavily greased with tallow. The mould was then bolted down tight, so any keratin that flowed was contained and the inherent layers compressed. A number of these forms were stacked, and often covered over to retain the heat. Steaming was not used in this particular branch of the horn trade, nor in the allied branch that flattened and split horn into sheets used to glaze oil-lamps (lant-horn = mod. lantern) or glaze small window openings.

Do you happen to know what temp the mold would have to be heated to? I think I might have to mess around with this one of these days. Sounds like fun.

Here's a pic from an excellent french book - Rasoir a Droit - that shows a later version of the press. I doubt that they changed much over the years, though:



BTW, I work with a lot of old razors and when the blade is being re-pinned you can often open the scales and see the horn-pressers or plate-makers initials on the inner surface of the scale. Sometimes they look crude and scratched on, sometimes they had been delicately carved into the steel. A wade and Butcher I was working on a few days ago had a very neatly inscribed 'W*F" on it. Echoes of a long dead hand and a part of history that we don't know enough about.
