Colonial Archaeology: 070 333 Spring 2006 Prof C. Schrire [email protected] Room 201/202 RAB Phone: 932 9006 Course Outline: This course will teach the rudiments of identification and analysis of colonial artifacts dating from about 1600-1900 AD. Our teaching collection includes a variety of ceramics, pipes, glass and small finds. The course if taught largely by supervision and not lectures. Students will sort collections, draw objects, measure objects and identify them according to numerous criteria. Course Requirements: A prerequisite for this course is 070: 208, Survey of Historical Archaeology, normally taught in the Fall term.

Title: COLOR IN SALT GLAZE. , Abs tract approved: This thesis endeavors to bring a brief history of salt glaze to the reader, following i~s ge~esisin Germany to England and the American colonies and its continuation to the prese~t day. In order to conduct research on color in salt glaze~ a kiln had to be built for this purpose, meeting all the requirements 'that this tech- nique demands. Studies were ~ade on clay bodies to determine their throwing qualities as well as their ability to take a salt glaze. Finally, research was carried out 'in many serfes of tests studying the reactions of'various engobes and other coloring materials when ,fired in the salt glaze kiln. \ .'

Floor Tile Glass-Ceramic Glaze for Improvement of Glaze Surface
Journal of the European Ceramic Society xxx (2006) xxx–xxx Floor tile glass-ceramic glaze for improvement of glaze surface properties Bijan Eftekhari Yekta a,∗, Parvin Alizadeh b, Leila Rezazadeh c a Ceramic Division, Department of Materials, Iran University of Science and Technology, Tehran, Iran b School of Engineering, Tarbiat Modaress University, Tehran, Iran c Ceramic Division, Materials & Energy Research Centre, Tehran, Iran Received 16 September 2005; received in revised form 4 December 2005; accepted 28 December 2005 Abstract Simultaneous improvement of surface hardness and glossiness of floor tile glaze, without changing its firing temperature, was the main purpose of the present paper. Thus, various glazes in the system of CaO–MgO–SiO2–Al2O3–ZrO2 were prepared and their crystallization behaviors within a fast firing cycle were investigated. With increasing amounts of calcium and magnesium oxides to base glass, the optimum glass-ceramic glaze was obtained. The results showed that with increasing of CaO and MgO part weights in frit, the crystallization peak temperature was gradually decreased and the intensities of diopside and zirconium silicate were increased. The comparison of micro hardness for the optimum glass ceramic glaze derived in this work with a traditional one used in floor tile industries indicates an improvement of 21%. It was found that the glaze hardness not only depend on the amount and type of crystalline phases, but also on the residual glass composition. Furthermore, it was observed that the glaze micro hardness is only slightly affected by thermal expansion mismatch of body and glaze. © 2006 Elsevier Ltd. All rights reserved.

Wollastonite–A Versatile Industrial Mineral
Industrial Minerals of the United States Wollastonite–A Versatile Industrial Mineral What is Wollastonite? Wollastonite is a chemically simple mineral named in honor of English mineralogist and chemist Sir W.H. Wollaston (1766–1828). It is composed of calcium (Ca) and silicon and oxygen (SiO2, silica) with the chemical formula CaSiO3. Although much wollastonite is relatively pure CaSiO3, it can contain some iron, magnesium, (Above and right) Hand specimens of manganese, aluminum, potassium, wollastonite showing acicular crystal clusters. sodium, or strontium substituting for calcium in the mineral structure.

Development of a Glass-Ceramic Glaze Formulated from Industrial Residues to Improve the Mechanical Properties of the Porcelain Stoneware Tiles
ABSTRACT TO THE WORKSHOP: VITROGEOWASTES, Elche, sept 2017 Development of a glass-ceramic glaze formulated from industrial residues to improve the mechanical properties of the porcelain stoneware tiles. E. Barrachina1, M. Esquinas2, J. Llop2, M.D. Notari2, J.B. Carda1 1 Department of Inorganic and Organic Chemistry, Universitat Jaume I, Castellón, 12071 (Spain) 2 Superior School of Ceramic in l´Alcora, Castellón 12110 (Spain) ABSTRACT In this research a mixture of 90%wt of industrial residues (recycled soda-lime glass and ashes from a coal power thermal plant) have been vitrified for their use as “secondary raw material”. Then, a glaze suspension was prepared to be applied as a glaze suspension on the porcelain stoneware tile. The tested pieces have been fired by a conventional porcelain cycle at 1180ºC of maximum temperature. The XRD, XRF, SEM/EDS and the dilatometric analysis have been the instrumental techniques used to characterize the final material. Finally, an ecological glass-ceramic glaze perfectly fitting on porcelain ceramic tile has been produced, exhibiting a unique phase, anorthite, which ensures a high flexural strength (around 96 MPa) and a significant Vickers microhardness of 250 GPa, improving the mechanical properties of a conventional the porcelain ceramic tile. Keywords Circular economy, revalorization of industrial waste, glass-ceramic glaze, porcelain stoneware, mechanical properties 1. Introduction Citizen environmental awareness has increased in the past decade, due to the publication of many studies on the impacts of environmental degradation. In that sense, scientific research is contributing to arouse public awareness about the new technological challenges in society. One of the concepts which at the moment seems to be proliferating in a significant way is the circular economy. -

Extremely high Pb concentrations were measured in personal and indoor air samples, household surface dust samples, and household soil samples. Personal air Pb concentrations for workers performing pottery firing and glazing were up to 454 g/m3. Results from indoor air samples indicate that airborne Pb concentrations were lower during nonglazing period compared to the glazing period. Soil Pb concentrations measured in 17 homes ranged from 0.39 to 19.8 mg/g. Dust Pb loading on surfaces of household items, hands, and clothes of a worker ranged from 172 to 33 060 g/f t 2. -
