Abstract

[[abstract]]The objective of this research is to present wood and vegetable ash glazes production model. From generally marketed wood and vegetable ashes ingredientanalysis and comparison; preliminary examination, discussions with experts,the Casuarina spp. Ash was chosen for the experiment model, using wood and vegetable ash glazes preliminary production model to execute the experiment, and according to the experiment results modify the wood and vegetable ash glazes burning experiment model. Finally, the research conclusion and modification to wood an d vegetable ash glazes burning experiment model is applicable for suggestions to The Living Technology Curriculum of Middle School teaching's. The research conclusion is categorized as follows:1.Wood and Vegetable ash glazes burning experiment model and variables that affectit (1)Factors that affect wood and vegetable ash glazes burning's result variable are: a. wood and vegetable ashglaze's variety and ingredients; b. the processing method of wood and veget able ash glazes; c. the fired atmosphere of wood and vegetable ash glazes; d. the firing temperature of wood and vegetable ash glazes.(2)The wood and vegetable ash glazes firing experiment model is constructed fromvariables in the processing of wood and vegetable ashes, variables in themixture of glaze's in gredients and methods, variables in tiles quality, and variables in the firing temperature.(3)The reasons for application of wood and vegetables ash glazes firingexperiment model at current Living Technology Curriculum: a. It is suitable for the current objectives of Middle School Technology Curriculum; b. It is applicable to the concept of STS; c. It is applicable to the concept of MST; d. It is possibly applicable to the present manufacturing techno logy system teaching strategy.2.A Comparison of the ingredients found in the wood and vegetable ashes commonlyfound in Taiwan, and those other complex wood and vegetable ashes available inthe market:(1)The wastage of Na2O of the usual wood and vegetable ashes in Taiwan beforeand after washing is 37.73%, the wastage of K2O approximately at 41.86%, thefiring wastage of washed ash is smaller than pre-wash ash.(2)The firing wastage of the usual wood and vegetable ashes found in Taiwan are lower than the complex wood and vebetable ash.3.The performance of Casuarina spp. ash mixture glazes:(1)There is no significant difference in the firing result between washed and prewash Casuarina spp.;(2)Pe rformance of Oxidizing fired and reduction fired in melting, mixing and the glaze color appear differently.(3)The tiles quality affect the fired glazes'color and product pattern.(4)The firing result of different tiles group is similar.(5)The glzes' combination that are close to Casuarina spp. ash edge, majority carry milky, crack, stringing etc scenario ; The glazes combination that areclose to Naku feldspar edge, majority carry transparent, crack, stringing etc scenario; The glazes combination that are close to the clay edge, majority carrymilky, crack, a little string, glazes layers are thicker etc scenario.
