Vase designs  

Thanks, Patrick.
I might as well display two other sketches that were made during the previous discussion. Don't know if there's anything useful here. . .

The first sketch is great SDR,I like the way it slumps and looks loose. I'm again grateful you took time to do it. I think a parchment colour would look quite good, I'll talk to a ceramics teacher I know and see if she thinks anything can be done with the idea, I might be able to con her into getting a student to have a go.

Yeah, I
like the softness of it, too. The first one I did (not shown) had the same spiral but was squatter and. . .just sat there.
It would be fun if someone wanted to try to make it work.
The plan views were of other vases that would have various levels, with dividers to separate and support the stems -- as many of the other designs showed.

Hey SDR, I spoke to a ceramic...
Hey SDR, I spoke to a ceramicist today about the parcment roll and she thinks its do-able and knows a chap who makes molds cheaply, looks like shes is prespared to help on the design. I'll let you know how it goes.

I'm not sure
if this piece could easily be cast; I'm thinking it might want to be hand-built, coiled up from a single piece, with a bottom disc. But I'd be interested to know what a ceramist would suggest.
Here's my idea of the opposite side of the vase:
This is the approximate plan at the top:
and the approximate plan at the middle and the bottom:

.
Another try at the middle and the bottom:

yeah , my thinking was that...
yeah , my thinking was that it would be a bugger to cast aswell and that I might try to roll it up with a layer of neoprene or rubber and cloth, wait for that to dry off a bit pull out the neoprene and then do the base by hand (if what I remember from high school art is correct) but she said to just do elevations and a cross section and she would consider it. I will probabaly do a fairly regular (perpindicular) set of drawings and see how it goes.

Sounds good.
I did just enough (?) ceramic work in college to have some idea of the material (s) and the limitations. I hadn't heard of the neoprene trick -- that's interesting.
A friend who looked at the first drawing said "how does it hold water ?" I figure if the closure occurs at the bottom two-thirds that should be good enough ?

This is
my impression of the vertical section:
Two concentric rings at the bottom serve as a "frog". . .

I don't know if the...
I don't know if the foam/neoprene idea will work, it was just an idea I had off the top of my head. I agree about the 2/3 up the side idea, perhaps a little higher? I was thinking of having the spiral run the full height of the vase, it strikes me that would be easier in terms of production, but we'll see.

.
You might be right about that -- and it would eliminate the need for a frog at the bottom, and probably be stronger, if heavier. I show a fairly thin wall thickness. . .
Cleaning might be an issue with this piece, but a bottle brush would probably take care of it.

SDR...
This vase took me along time to respond to because the first drawing seemed too sand castle-ish for my taste. The spiral builds to predictably to be interesting.
But the drawing from the opposite side really appeals to me. I would like the entire vase to sit like a slightly unfolded scroll. If that's what you have in mind here, then it would be very pleasing to the eye and allow a spiral distribution of the flower arrangement.

If anyone wants to have a go ...
If anyone wants to have a go at making such a thing I'd like to see the results. I'm going to try rolling it into shape on the weekend before I put the effort into full size technical drawings.

Hi, HP, SDR and DC
I love the principle, but I can't see how it could be done other than so called slab-building. Even than the spiral hanging somewhere in the air has to be supported until dry..or almost. It means that any kind of support has to be taken out from the top between the walls of the spiral. I am sure the spial wall will break before that support is out, even if it is a foam. One possibility is to put light styrene foam in the vase and hope that it will absorb the shrink of drying. The styrene can be left inside as it will burn during the firing, leaving no residue. Sometimes simple and logical shapes are extremely complicated to make. This is a good exemple....but I am going to give it a try...and let you know.
