ABAD: alum block acquisition disorder, I like it. A couple of years back, I bought a block of the Portuguese 444 alum as it was larger and cheaper than Osma. As received, it had bumps and pits all over. I used it thinking that these would eventually smooth away. Eventually, I finished it. When I moved on to an Osma block afterwards, it was like moving to silken sheets after sleeping in burlap. The Osma was very smooth, out of the gate.
Striving to be brief, I become obscure. --Horace
