Lewis & All,

I make tiles two ways, 1. with an extruder, and 2. by rolling out and
joining small slabs.

My extruder shapes are like the letter capital "L" w/ textures extruded w/
the tile strip. They are free standing, about 3" high and when cut, 1"
wide. The front of the leg part has smooth wide groves in the top third,
close sharp groves in the mid third and no texture around the bottom third.
The "toe" provides a protected place to label. After bisqueing, they stack
& store nice and compact.

My slab test tiles are cut from slabs 14"x14"x1/4" thick w/ a 1"x1" base,
and a 1"x1&1/2" upright. I use a 1" wide strip of wood as a guide for the
base, and a 1&1/2" strip for the upright. After marking the slab for the
uprights, I use a plastic fork w/ smooth tines to press grooves into the
clay before cutting to size. The bottom of the uprights is dipped into slip
and pressed onto the base. I can do about 100 of these in 90 min. from slab
to tile.
