Can you make an egg?

When JoAnn was studying art at Eastern Washington College of Education, one of her instructors demonstrated how to make realistic shaped plaster eggs.  She applied this process to create a large 12" long plaster egg that she used as a model to form a mold over.  After removing the plaster egg she used the mold to cast a large blue resin egg with a figure inside.  This was described in my recent post, "Memories of an Art Exhibit" as part of one of the pieces on display.

I decided to include this process in my art work so here are the details.  You will need Plaster of Paris, a small neck container like a wine bottle and a medium sized rubber balloon.  Mix the plaster to the constancy of  medium thick gravy, then pour it into the container.  A plastic funnel makes this transfer much easier.  Now blow the balloon up to the size you want the egg to be and a slight bit more for lost air in the next steps.  Quickly slip the balloon over the neck of the container without loosing too much air.  Invert the container and transfer the plaster into the balloon.  Remove the container and tie off the neck of the balloon.  Gently rotate the balloon while tipping it back and forth so the ends also get coated.  This will take some time until the plaster sets up.  Try hold the balloon in the palms of your hands so as not to make indents with your finger tips.  When you detect the plaster has set and is no longer flowing inside the balloon, carefully set your project down and let it dry until the next day.  The balloon comes off easily if you pull out on the end you tied and start a cut in the rubber.  Usually it will tear itself open as it contracts, leaving a smooth white egg.

At this point the egg is quite sturdy if you have used enough plaster to build an 1/8 to 1/4 inch thick shell.  It will brake if you drop it however.  I chose to coat my egg with hardwood segments in a mosaic pattern and finish it as I have the vessels I make.

This project needed a stand to hold the egg while it was on display, so I fashioned a bulky, free-form stand with a recessed area lined with sheepskin, wool side out.  When placed in the "nest" as I refer to it, the egg snuggled down and I felt was secure enough  to go to an exhibit.  It would need a name so was christened, "Woodpecker Nest".

All went well as it traveled around to different exhibits and was stored in the various homes we moved to, but gradually I noticed some cracking occurring between wood segments.  I filled the cracks as shown here with red resin and refinished the entire egg with a clear finish that would seal moisture out and prevent further cracking.  Now Humpty Dumpty has age marks but no further problems have occurred.  If I had it to do over, I would fiberglass the plaster egg and then apply the wood over that, thus giving a fiberglass shell similar to the vessels I make.

I had fun making an egg.  You should try it sometime.
