Is there a trad glue made from horn?

[stuckinthemud]

I know about glue from casein (cheese), rabbit/hide glue (protein) and gelatin (collagen) glue but I stumbled over a passing mention of horn glue on line. Horn is keratin. Is there a traditional glue made from animal horn? If so, anyone made/used it?

The closest would be cow gum …made from the hooves of cattle which is keratin the same as horns. Not sure of why you would use it for wood though. It’s available on Amazon
