Re: Egg shaped
hi gil, thanks for sharing these hands on skills. i don't understand why you would say this should be off line when what we are talking about is prep storage and empowering a person to do it themselves rather than rely on an outside source. seems like it is very ,on topic, as many of the posts make no mention of biodynamics. not that i don't learn from them and mostly enjoy them. thanks again. :)sharon - Original Message - From: "Gil Robertson" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, August 29, 2002 12:42 AM Subject: Re: Egg shaped > Hi!

Re: Egg shaped
Hi! Sharon, This maybe should have been off line. There are many ways of making free form shapes from clay. (A distinct from thrown or slip cast.) The best known is "coil". This is like the kids plasicine. The clay is rolled out into "snakes" and built up in spirals. The surface is smoothed off while still damp. Very complex shapes can be built this way. "Bat and ball" is another, where small balls of soft clay are placed in position and beaten into place and shape with a small wooden bat, made from a scrap of timber. The easiest is the "plaster mould" method. As you want an egg shape, find a balloon that when inflated is the right size and shape. Bury the balloon in the slightly damp sand, to the half way point on the long axis. Use some sort of form and cast a block of plaster of paris to cover the exposed part. One can then construct a form in the mould, using slabs, coils or balls of clay. When that section is formed, carefully remove and rotate about ninety degrees and continue. Then turn again and finish the full 360 degrees. One has to leave a hole to get your hand in. I assume you need an opening and a lid. The lid can also be made in the same mould. If one has a tame potter, use a clay like they do and get them to fire it for you. If not, hit Google and put "pottery" in the first line and "primitive firing" in the second. You can then fire your own.

Re: Egg shaped
hi gil, I'm sure those things are to be of foremost consideration, but ,,, it seems worthy of a trial here with using the gourds as a vessel to make 504 and bc. . last time i tried 504 there wasn't much left in the ground. the worms must have et it. as to the b.c. it is quite expensive and hard to find a clean , small wooden keg,as recomended. i'm sure in the old days they were very easy to find , but these days one has to pay antique prices. alternatively, hugh c. said one could construct a brick pit., but i really like the idea of something grown here and the round shape, wonder if i can talk a gourd or two into growing into an egg shape for me ! we are doing some homeschool projects with clay this fall with primitive firing. It that would be fun to try our hands at making an egg shape on another subject.. rain, rain at long last in southern delaware, both rain barrels full and still gently coming down. hallalujah! :)sharon - Original Message - From: "Gil Robertson" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, August 28, 2002 6:21 PM Subject: Re: Egg shaped > Hi!

Re: Egg shaped
Hi! Dave & Ron, I wonder if shape is as important as other factors in Prep storage? I would think:- ventilation, humidity, natural materials, temperature and temperature stability, minimal vibration and isolation from strong electro/ magnetic fields,. would all be of more important.

Here's an interesting link on the mathematics of the form http://www.anth.org.uk/NCT/path.htm Interestingly, the egg shape and the vortex can be described with the same math, just change the parameters.
