While all sorts of inks from lamp black to India ink have been used for scrimshaw, artist oil paints work just as well and are not as messy and easier to work with. For black scrimshaw, Ivory Black oil paint works well. For color scrimshaw both oil and colorfast watercolors can be used. Water colors are usually sealed afterwards but oils don't need it.

You could use the word scrimshaw in a sentence by saying, the intricate scrimshaw work done on that piece of ivory is amazingly beautiful. Scrimshaw is intricate engraving done on bone or ivory.
