Here is my first Fat Baby Bird cast in cement. This is the first cement “pour” in my new mold, and this mold is fine! Unfortunately my casting was flawed; I did not mix enough cement, and with the RapidSet material mixed fairly thick for strength, the layers show. So this first cast is far from perfect, but good enough to prove the mold and to please me. After all I know that I can do better with the next one!
I rather love the air bubble that was trapped in the eye. This accidental void actually perfectly matches the personality of my quirky fat baby bird, and makes this first proof special. So a good several days work, I think. And I will make another fat baby bird cast today.
Time passes … and we have the second cast. This time I mixed enough material, BUT I used a slightly different mixture (RapidSet CementAll instead of the high strength Mortar Mix). This seems much harder to mix well: it was lumpy and since it sets so quickly, I get in a hurry mixing it. I fear there are weak spots in this cast, where there were unmixed dry lumps of cement! I don’t seem to have any trouble mixing the Mortar Mix, which has a larger grit sand, I think. The dry material did not seem lumpy, but perhaps I need to mix it more, or even sift it before adding water. That would be a big pain!
