MONOCHROME CUT WORK ON IVORY PIANO KEY PIECEI was curious if ivory and bone could be burnt. As you can see by this example, it can, but there are several structural problems involved, including heat fracturing of the ivory and some fading. (It's interesting to note that tagua pyrography does NOT fade.) This piece was produced by using a super sharp skew and performing small micro cuts.The actual size is seen below. |  |
