Fred -
I teach ceramic history every other fall, and so this is something I have
pondered on and researched. There are few examples of slab-built work in
historical pottery until the modern era and no real continuity in the
development and use of slab-construction until the advent of the
slab-roller. In ancient and tribal work, I think it simply had to do with
the difficulty of making flat, uniform slabs, which at the least requires a
very flat surface to roll upon, and a very uniform mallet or roller to
compress and expand the clay. Both would have been possible in any fairly
advanced civilization in the past, but perhaps not in tribal cultures.

I have never come up with a good theory about why so few of the more
advanced historical cultures used slabs, especially considering the
extraordinary craftsmanship and control of materials exhibited in many
different media. Japanese Haniwa tomb figures were made with a combination
of thrown, handbuilt, and slab-formed components. Mesoamerican cultures
used a lot of slabs, and if you can specifically find images of Zapotec (a
branch of Mayan) censers (large incense burners), you will find very
creative use of slab-work, usually in combination of coil-building and
press-molding.

So, I guess there is no real "evolution" of slab-built pottery until the
post-WW-II period.

Hope that helps.

There's only a limited comparison, because there is no precedent for the

Hi Vince and all,

Does the use of an extruder follow a similar historical trend?

If so, would you suppose that this "recent" evolution may be related to the
march into the industrial age that spurred thoughts of producing
slabs/extrusions via machine? Perhaps as a result of wartime production
needs.

Thanks,

Hi, Vince, Larry...

According to the only textbook I know of on ceramic extrusion and it's
history, Extrusion in Ceramics, by Frank Handle, ISBN 3540271007,
ceramic extrusion has existed since at least 1619 C.E. (A.D.). The
author cited three types of extruders in use back then to extrude
plastic and semi-plastic clay, the piston extruder, the auger
extruder, and something called a roll extruder, with the auger
extruder being the most popular. They were used to make ceramic
construction components, not art ware.

I seem to recall reading somewhere that pug mills weren't invented
until the mid 1800s, but I could be mistaken.

And don't forget the Play Doh fun factory, possibly the greatest
application of extrusion technology in the history of the world!

For whatever it may be worth.

Not sure I agree with you on the extruded use since the G.I.Bill.
I have been to Portuguese sewer pipe factories and Italian=3D20

Hi Marcia,

I'm sorry, as usual I typed one thing and really ment another....

I guess my question was more about the use by studio potters rather than
industry. Was the influx of machinery into studios due to the populations
exposure to mechanized production techniques or was it due to an expected
(and definable) evolution in technique?

I'm always intrigued with the impetus of development. Just what triggered
this advancement after many centuries of hand construction with little
mechanical advancement. With no clear march towards mechanization, then
there is a sudden influx of machinery into our studios after WWII. Or am I
not seeing the whole picture?

I did a workshop with Rudi Autio in the seventies. He said he learned his
slab technique- throwing large lumps of clay down with a glancing blow flip
and throw again this streches the clay out into a slab- form brick makers.
