For the difference in properties for the Quartz size the 30 size was the outlier in all trends it also had the highest standard deviation in the Dry, suspended, and saturated samples. There was not enough difference in data to validate the removal of outliers. If the 30 quartz size is not taken into account the weight of the samples increased with a increase in quartz size. For the average bend strength there was no trend in strength based on the quartz size most of the samples where within standard deviation of each other. This result can be expected because of the testing method used and the number of samples. Porcelain has randomly dispersed intrinsic flaws location and sizes, so the values of the sample would be different if the same samples where tested on the half’s of the original sample. A material is only as strong as is largest intrinsic flaw. The bulk density, apparent specific gravity and percent open porosity is shown in table (4). There was no significant difference between in the bulk density and apparent specific gravity of the samples. This shows that the amount of air in the samples are the same thought the quartz sizes. For the percent open porosity there is also a deviation from the 30 quartz size. Ignoring that size the amount of open porosity increases with the increase in quartz size. This makes sense given the fact that the larger the quartz size the easier it is for unwanted materials to burn off such as hydrocarbons. Table 4: shows the bulk
