This was actually an ostrich egg that was left over from a dozen that I purchased 20 or 30 years ago. I began repurposing the egg about three years ago, thinking that the original design could be made into a mosaic design. I used chicken egg shells, cracked and emptied (for breakfast, ha ha) and washed and dyed in pysanky dyes just slightly crunched into small shapes and applied them with weldbond glue. I have put a couple of layers of varathane on this egg, i am hoping to put many more on, sanding lightly between, to achieve a smooth finish (as the egg shells are NOT smooth obviously, ha ha). I didnt “grout” the spaces between the egg shells since there was already color on the egg which showed between the tesserae.
I will post a finished egg… I have no clue if the layers of varathane will ever create a smooth surface. I am going to use a random sampling to estimate the number of pieces… ha ha. So i cut out of paper a frame of one sq inch, and held it over 8 different places on the egg and determined the mean number of pieces per sq inch was right near 60. I went online and googled “surface area of an oblate ovoid” and found two websites with a free online calculator. I put in the three measurements (3″ 3″ and 2.5″) for the ostrich egg and it came up with 89 sq inches, which ends up being just over 5300 pieces of egg shell glued to this ostrich egg. ha ha
