Scrimshaw on Cattle Horn

(Originally posted in our newsletter in September 2014)

Cattle Horn in handWhat is cattle horn?
Cow horn is comprised of keratin, the same material your fingernails are made of, as well as hooves. Cow horn differs from Antler in the fact that antlers are actually bone with no covering, and they are often shed annually.  Horns are not shed by cattle, in fact the only animal that does shed it’s keratin is the pronghorn.

Horn is somewhat thermoplastic – it can be heated and shaped, unlike ivory which takes chemical processes or carving to change its shape.

How is it used?
Horn has probably been used for items of adornment and practical use since before the domestication of the animal. From drinking vessels and helmet ornamentation to buttons, knife scales, belt buckles, and combs to powder horns and pen holders, horn can be a versatile material.

Hardness
I couldn’t find any hardness scales using the Rockler D hardness to compare it to. As far as scrimming with my Coulter scribe, it’s slightly softer and sinewy.

Colors and Source(s)
Cow horn comes in a variety of colors from black to mostly white. Usually there is some mottling often with a darker tip. The quality varies as well depending on the cattle the horn originally came from, ranging from sinewy to almost smooth. You can find cattle horn online either raw, polished or in kit form to create powder horns.  One of the better places we’ve found is http://www.powderhornsandmore.com/ with a beautiful variety. They also have a newsletter to keep you apprised of shows, meetups and more.  You can find other cattle horns on ebay, one of which I’d picked up and was not impressed. It is unsuitable for scrimshaw (not that it said it was scrimshaw quality), so I learned.

We picked up a “scrimshaw quality” horn from powderhornsandmore.com to work with which has been in my “scrimshaw to-do” box for some time with the intention of creating a powder horn.  Sadly, with so many other projects going on it has sat there for nearly two years, and I’m sure it would sit for several more if I don’t do something with it, so we’re going to use it to test and review.

 

Cattle horn lightly sanded and polished with sharpie, India ink and oil paint to the left and to the rightStainability
We lightly sanded and polished the horn further with some of the inherent texture still showing, then polished one site with “HUT PPP (Perfect Pen Polish)” wax using a Dremel tool with a felt wheel, and another site we coated with “Renaissance Wax” – a favorite polish and preservative for ivory and wood.

After wiping the pigment away, the sharpie held to the polished areas.

  • Sharpie Results: Held fast until I rubbed it with nail polish remover (makes sense as it’s the same material)
  • India Ink Results: wiped away easily, stayed in the crevices of the texture of the cow horn
  • Oil Paint Results: wiped away easily, though stayed in the crevices of the texture of the cow horn.

Sanding completely smooth will create a cleaner image once you’ve done some scrimshaw, nail polish remover works well for cleaning it off, and the pigment does stay in the scribed lines.

Scribing

Two ships hastily scribed onto the cattle horn

Horn has a definite grain to it running from the base to the point.  This can cause some tools to stick unless they’re extremely sharp. That being said, it does scribe well. Scribing deeper may make the lines slightly “fuzzy” due to the fact that the ink will wick somewhat into the grain.

I sketched a couple of quick ships onto both sides of the polished areas to scrim. Initial cleaning left the ink as before, and most of the oil paint wiped away.  Another application of nail polish remover left the ink and the oil paint in the scribed lines. Some of us (myself included) like to scribe the initial image, ink it, then fill in. this can be an issue when it comes to cow horn if you’re using nail polish remover to clean it in between scrimmings, since it not only cleans away the ink, but also removes some of the wax or polish.  In case you like to work this way, we’d recommend either scribing in one sitting or scribing, cleaning, repolishing (HUT PPP was has worked the best) then let it sit for a day before moving to the detail work and shading.

Close-up of ship in progress on cattle hornDue to the holiday weekend and relatives that flew in from Michigan and D.C., I wasn’t able to do more than this hurried test. Since cow horn is malleable, I may decide to create several smaller pieces from it after sanding it down again, having learned quite a bit from this experiment.

 

Polishing/sealing
Once you’re satisfied with your work, a final coat using either renaissance wax or HUT PPP wax works well.

 

Conclusions
Sanding the area you intend to scrims as smooth as possible is a prerequisite unless you are looking to keep the rougher “aged” look of your scrimshaw,

Oil paint works best, though India ink works as long as you have some nail polish remover handy

Nail polish remover will remove the wax, be sure to repolish and let the piece set up for a day before continuing if you tend to scribe/ink/scribe/ink.

 

Jason's Horn (left), my horn (right)After completing this article I was talking with another scrimshaw artist who promptly sent me the horns he’d hand sanded and polished to 8000 grit then buffed with white tripoli polish.  The results are night and day. Where my hasty polishing resulted in a dull finish with crevices (right), his is glass smooth (left).


We’ll be resanding the white one properly before the holidays and creating something or things from it, though time still does not allow for me to create a powderhorn as intended.
