Yesterday, I did a small batch with a FO that 50% of the reviews said behaved perfectly, and 50% said it accelerates like a freight train. So being the sensible individual I am, I divided the batter for a 6 color swirl, and also included honey in the recipe. Weird results: my water-soluble TD and Trial by Fire Mica barely accelerated, Key West Blue and I forget which yellow went medium- thick trace, and Koi orange and Metallica brown became un-pourable almost instantly. Since some of my batter remained pourable, I did my rounds of layers as planned and tried some swirls, but mostly wound up shaking the mold (loaf) to get the runny colors to fill in the gaps. Some air holes in the brown, but still colorful, the fragrance (BB Woodland Elves) is to die for, and it was with a new recipe anyways.
Also, I wanted some solid acceleration experience ahead of attempting my first attempt at a marble pour today, since I wanted to use acceleration to get good veining (different FO, though). I have mixed feelings about how that went, but I'll have to wait until tomorrow to see the cross-cut.
