Designing 21st Century Standard Ware: The Cultural Heritage of Leach and the Potential Applications of Digital Technologies
No full textThis practice-based research investigates the potential applications of digital manufacturing technologies in the design and production of hand-made tableware at the Leach Pottery. The methodology for the research establishes an approach grounded in my previous experience as a maker that is informed by an open, experimental, emergent, and responsive framework based on Naturalistic Inquiry.
A critical contextual review describes the cultural heritage of Leach which, for the purposes of the research, is developed through the Leach Pottery as a significant site, the historical production of the iconic Leach Standard Ware and the contemporary production of Leach Tableware. This is followed by an examination of Potter’s Tools in the Leach production environment, and a review of makers’ digital ceramic practice.
The contextual review is followed by an explication of ‘standards’ presented through visual lineages of Standard Ware and Leach Tableware to define ‘standard’ at a design (macro) level, followed by an examination of how ‘standard’ operates at a making (micro level) level. This chapter presents new knowledge in relation to defining the visual field of Leach Pottery tableware production and its standards of design.
A chapter focussed on practice presents the outcomes and analysis of my engagement with digital manufacturing technologies which resulted in the development of new tools to support Leach Tableware production and the interrogation of Leach forms, in different mediums, which led to the creation of Digital-Analogue Leach forms. The practice culminated in the design and development of new 21st century Standard Ware: a range of 9 forms, called Echo of Leach, that were developed by myself using digital and analogue methods: the designs were realised by myself, the Leach Studio, and a further four makers. The outcomes of the research were presented in a three month exhibition at the Leach Pottery in 2013.
The conclusions of the research draw on the key points raised in the analysis of the practice and relate these to the approaches to making pottery that are highlighted in the cultural heritage of Leach in the contextual review. These are also discussed in relation to ways in which these findings could be taken forward into development of knowledge about Standard Ware, especially in a broader studio pottery context
A simplified model for Anglo Platinum's continuous secondary leach in the base metals' refinery
No full textIncludes bibliographical references (leaves 80-82).An Excel-based mathematical model simulating the Base Metal's Refinery Secondary Leach operation is developed in this thesis. Fundamental building blocks of batch leach data, equipment specifications, process conditions and feed characteristics are used to develop the model. The aim of which is to develop a tool to verify actual plant performance against theoretical performance and assist with troubleshooting in the plant or serve as a basis for future autoclave design. In the present study the model is specifically used to investigate the cause of the reduced leach efficiencies that the plant is experiencing

Microfluidic solvent extraction of platinum and palladium from a chloride leach solution using Alamine 336
No full textMicrofluidic solvent extraction (μSX) of platinum and palladium from chloride leach solution using Alamine 336 had been conducted. The leach solution was produced by leaching of spent automotive catalysts. A microfluidic Y–Y channel embedded in a Pyrex™ microchip was used as the extraction system. Platinum and palladium extractions (>99%) occurred at μSX contact time as fast as 1 s with subsequent marginal extraction efficiency increases for longer contact times with comparable extraction performance to that of bulk SX. Findings from this preliminary study are useful in initiating a new metallurgical technique in the field of recovering precious (high-value) metals present in low concentrations which are otherwise not technically amenable (or economically viable) to extraction using current conventional methods

Genoveva Leach Collection
No full textThe Genoveva Barrera Leach collection includes twenty-six negatives and a few photographs of early 1900 scenes in Premont, Texas. Correspondence concerning the family, schools, and conditions in Premont when wild burros roamed the streets is included along with financial records of Cibolo Ranch where Genoveva Barrera Leach was born and grew up. Leach graduated from Texas College of Arts and Sciences. She taught at Cibolo Ranch, La Copita, and Premont schools. A great reader and local historian she preserved papers and items she donated to South Texas Archives
