99 Things about ceramic mug Making - ten

82. Thermogravimetric analysis ------ A method of recording the weight change of a sample resulting from a change in temperature or time during heating.

83, mud thixotropy ------ mud vibration and stirring, viscosity is reduced, increased fluidity, after a period of time, the mud again thickened performance.

84, plasticity ------ Containing the right amount of water mud, under the action of a certain external force deformation without cracking, remove the external force still maintains its deformation performance.

85, drying shrinkage rate ------ after the sample molding and drying to constant weight after the length of the difference of the molding length of the percentage of drying line shrinkage; The percentage of the volume difference to the volume after forming is called the shrinkage of the drying body.

86, firing shrinkage ------ The percentage of the difference between the length of the sample before and after firing and the length after drying to constant weight is called firing shrinkage; The percentage of the volume difference to the volume after drying to constant weight is called sintering shrinkage.

87. Bus shrinkage ------ The percentage of the difference between the length of the sample after molding and the length after firing to the length after molding.

88. Firing temperature ------ The roasting temperature at which ceramic products have the desired properties.

89. Firing range ------ For porcelain, it is the temperature range from vitrified porcelain to below the softening temperature; For pottery, it is the temperature range corresponding to the upper and lower limits of water absorption of the product.

90. Melting temperature range of the glaze ------ The temperature range between the initial melting temperature of the glaze and the ripening temperature.
