I thendid a dispersant test to find right amount of Darvan 7. Additions of Epsom salt solved the problem ofthe slip pooling at the bottom of the objects. Having done this, I then experimented with additions ofdifferent fibers to hold slip together while the paper burned out.I did three line blends of different fibers. Paper and Wollastonite were more successful then nylon, withWollastonite being stronger in the end result.If I knew at the beginning what I know now, having done the tests, I would have figured out a moreconsistent way of dipping or spreading the slip in the packs of cigarettes.For future testing, I would suggest increasing the percent of fiber in the mix as well as developing somemix of fibers to hold the slip together. Also, figuring out some system for burning out the paper with outdisturbing the slip might prove more successful.58
