The sediment sample is moderately sorted and is comprised of silt-sized angular mineral grains including common quartz and trace amounts of feldspar hosted within a clay-rich matrix. Rare grains are sand sized. Other minerals/bioclasts present in common and trace amounts include muscovite mica, biotite mica, tubular bioclast fragments and poorly developed/fragmented radiolarians.

The rock sample is moderately sorted and is comprised of silt-sized siderite grains hosted within a clay-rich matrix. Silt-sized quartz grains are common throughout. Pore spaces are also comprised of quartz cements. The rock sample is likely reworked from a proximal source area on the slope due to the angularity of the grains. -

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.

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. -

Optical Mineralogy in a Nutshell
Optical Mineralogy in a Nutshell Use of the petrographic microscope Slides borrowed/adapted from Jane Selverstone (University of New Mexico) and John Winter (Whitman College) Why use the petrographic microscope? • Identify minerals (no guessing!) • Determine rock type • Determine crystallization sequence • Document deformation history • Observe frozen-in reactions • Constrain P-T history • Note weathering/alteration • Fun, powerful, and cheap! The petrographic microscope Also called a polarizing microscope In order to use the scope, we need to understand a little about the physics of light, and then learn some tools and tricks… Polarized Light Microscopy Isotropic materials, which include gases, liquids, unstressed glasses and cubic crystals, demonstrate the same From Nikon optical properties in all directions. They have only one refractive index and no restriction on the vibration direction of light passing through them. Anisotropic materials, in contrast, which include 90 percent of all solid substances, have optical properties that vary with the orientation of incident light with the crystallographic axes. Anisotropic materials act as beam splitters and divide light rays into two parts. The technique of polarizing microscopy exploits the interference of the split light rays, as they are re-united along the same optical path to extract information about these materials. What happens as light moves through the scope? plane polarised light (single vibration direction) unpolarised light (all possible vibration directions) 1) Light passes -
