Basins and Bowls made on Semi-Automatic jiggers record

I came across heaps of Production records of various kinds at the Portage Museum yesterday when it was nearly time to leave.  I will have to spend a whole day processing them sometime.
It's great to see what was made this way and there is another record for cups made with jiggers.
However this record troubles me, in regards to the 7000 shapes, which relate to the Brick Clay vases.  I can understand the Stand for the Flower Pot being made this way, but not the vases.  As I have no hands on experience with Commercial Pottery production processes, I hope someone can help me understand this.  The 1949 Crown Lynn Film shows an Oval being made, which is all that I can relate to.

I have added the full description for my own benefit in brackets.

Ev, there are certainly lots of issues raised by this post.

I was not aware of the 7000s numbering for the "Rhodes" vases until now but if this is a unique numbering system (unlike the Wharetana which doubles up with castware numbers) then this firmly dates the vases post-1964.

The use of brick clay within CL and in particular with machine use for white clay is a worry.

Supposedly hand thrown made in a jigger ???

Can someone confirm throwing marks inside the Rhodes vases?

Legend of Maui made in a jigger ???

and so on!

I have two of those vases and they are certainly made to look like they are hand thrown, but the bases are shallow and are so similar they could have been made by a machine

I watched Charlie Seakins using a Crown Lynn semi automatic jigger to make plates a few years ago and it was so quick !!!

Steve Aitkin told me that he worked at Crown Lynn in the 1980's as a 'thrower' and had to put rings on plant pots to make them look hand made ..... he didn't say if they pots were cast or jiggered or ram pressed !!

Here is Morris and James making jiggered ware and I can understand plates and bowls and basins .... and I totally get it.

In the Modellers records there are drawings for jiggers for the Ringed Basins.  I can't find anything that relates to vases ~~~!!!!!~~~~

Many of those four digit numbers are in the Ram Press records :O

I don't believe it is possible to manufacture a vase with a waistline on a jigger machine?
Here are two Crown Lynn items manufactured on their machine, as its much quicker than using the slip casting method.

I have watched clay pots being made at the Crum Brick works in New Lynn, also concrete pots made from a sand and cement mix both on a jigger machine.

Thank you so much oakpot. Yes I can see those two being made on a machine and then decorated by Dan with his coloured slips.

Oak pot this is great info re the pot and base you posted. We're all the plant pots in this style made by jigger?

Maryr ,yes thousands of clay pots that shape were made on jigger machines.They were stacked inside one another and placed in the kilns.
Plastic planters put a stop to the sales as they were cheaper to make.

Thank you very much Oakpot. Have a lovely Christmas.
