The Search for New Red Pigments Limited pigment choices for porcelain stoneware tile led
to a search for new pigments or new synthetic routes for the
use of old ones in efforts to obtain different shades of red
and orange. F. Bondioli and T. Manfredini
One-Dimensional Packing of Spheres, Part I A new type of particle packing model that packs 3-D particles
along a one-dimensional line is neither limited by the large
memory requirements nor the long running times that severely
restrict the use of 3-D models. Part I of this two-part series
addresses monodisperse and bimodal distributions. Dennis R. Dinger

The Dynamics of Standards Development: Achieving
the Goals of Your Business, Your Industry
From ceramic tile to test methods, clays to nonplastic and health to international
issues, ASTM's voluntary, full-consensus, standards development process generates
industry-relevant documents that are global in acceptance and application.
Daniel A. Schultz
One-Dimensional Packing of Spheres, Part II
One-dimensional approach to the modeling of particle-packing phenomena represents
at least an order of magnitude enhancement in our capabilities to predict
particle-packing phenomena in real systems.

Reliability of Materials for High-Voltage Insulators
A comparison of the characteristics of quartz and aluminum oxide porcelain confirms
the technical advantages of the latter for the production of high-voltage insulators.
Reliability-particularly over long periods of time-is the priority.

Porcelain Stoneware Tile Surfaces
The behavior and performance of the proper surface of porcelain stoneware tile
is highly affected by processing, microstructure and material characteristics,
and machining procedures and parameters.

Specialty Additives Enhance Casting Slips
A general rule-of-thumb is that as casting rate increases, MOR decreases. However,
the use of specialty additives yields marked improvements in processing parameters
without traditional tradeoffs. M.J. Brezina and R.J. Thomas
Coverings 2000 Continues to Wow
Visitors
The Western Hemisphere's leading ceramic tile and natural stone exposition and
conference featured 1,056 exhibitors and welcomed more than 28,000 attendees
May 2-5, 2000, at Orlando, Fla. Christine J. Polas
Oil Field Sludge Used to Make Brick
Effluent treatment plant (ETP) sludge can be used as a component in the preparation
of common masonry brick. Properties are within acceptable limits and compressive
strength is high. Utilizing this sludge in brick preparation may eliminate disposal
problems. N.J. Saikia, P. Sengupta, D.K. Dutta, P.C. Saikia and P.C. Borthakur

Silica Exposure and Silicosis
There is no cure for silicosis. Successful treatment options are limited. The
best "cure" is prevention by limiting exposure. David M. Rosenberg, M.D., M.P.H.

New Facing Brick Factory in Operation in Spain
Today's technical possibilities make it viable to enhance automation and process
control systems via telemaintenance. Direct access to expert knowledge is the
ideal precondition for avoiding long downtimes in the plant.
Additive Interactions in Ceramic Processing
Interactions between the polymers typically used in the manufacture of ceramics
could be the root-cause of some common ceramic defects. B.R. Sundlof, C.R. Perry, W.M. Carty, E.R. Klingenberg and L.A. Schultz
Use of Albite Wastes in Stoneware Glazes
Albite flotation wastes are being used as a substitute for feldspar in stoneware
glazes, making it ecologically effective as well as economical. Münevver Çaki and Bekir Karasu
Developing the Optimum Vitreous Body for Slip Casting
The amounts of quartz, kaolin and feldspar that are used in a vitreous ceramic
body affect its physical properties and determine the quality of the end product. H. Gürkan Yersel and Ensar Tacyildiz
Pressure Casting Offers Possibilities for Technical Ceramics
Advantages of pressure slip casting over traditional shaping techniques make
its use desirable for the manufacture of technical ceramics. A. Salomoni and I. Stamenkovic
Modern Forming Methods for Tableware
New developments in the shaping of ceramic tableware via isostatic pressing,
pressure casting, hollowware casting and plastic shaping are highlighted. G. Seitz
Robotic Fettling of Asymmetrical
Tableware
A new fettling technology for use on all types of isostatically pressed flatware
has the capability of finishing the rims of any shape to a predetermined dimension. H. Bieker
Recent Advances in Dilatometry
