The first round of tiles for the filter clay temperature and shrinkage tests. Over 60 tiles to test at 925 950, 975, and 1000 degrees Celsius. We were sent between 250 and 500 grams of each sample, which turned out to be a little small. It took 100grams to make 4 tiles 2cmx10cmx5mm thick. and each time the particle analysis test was preformed we used 100grams as well. The particle analysis test takes 24hours to complete, and the firings about 6 hours, not to mention the prep and wait times. Our scale turned out to be giving bad readings so it threw off a lot of the data we collected. now we begin again.
