MY PLASTER PULP EXPERIMENTS BATCH 2 - ANOTHER UPDATE

In the previous update i mentioned a serious shrinkage issue due to i think an increase in un-accounted for water when i added more wet tissue pulp. I was going to make a third test batch today but i am simply not up for it as it turns out, not today. When i do (tomorrow, day after maybe) i will be reducing the tissue pulp content back to where it was during the first batch experiment. I will be draining the tissue pulp too before mixing, but more on that at the time of making the new batch. For now here is that shrinkage i mentioned. You may need to click on the image to enlarge it to see the problem better.


























I new there may have been 'some' shrinkage or extended drying issues from adding the extra tissue pulp. However a miss-judgement of the water in the soaking wet tissue pulp threw my calculations and expectations out more than i thought.

Never mind these samples can simply be re-mixed into a random batch later when fully dried.

More soon.
