  1. I've been studying some indigo properties and vat dyeing chemistry and i have no clue as to why you would experience excessive fading with warmer water. Indigo particles get lodged in between the monomers of a cellulose chain. It dosen't seem logical that 35 degree water would fade the indgio out that much more than say 20 degree. It takes a lot more extreme temperature and pressure to degrade cellulose. I though it was agreed that it is more the abrasion of going through a washing machine cycle than the actual water that strips the indigo. Maybe the warmer water acts negatively on the other organic elments of ai dyed pieces. Those japanaese fermentation dye pots have a litle bit of every thing in them and i think it is all that other organic material that lends that greenish cast to the natural dyed pieces. Those pots are kept at a stable 75~80 degrees F so anything warmer than that may cause degredation there. Sorry for ranting so much i've been thinking about htis stuff all day. Check the natural vs. synthetic indigo thread.....

    increase heat you increase the rate of reaction! general chemistry! increase molecular collisions and increase the energy of activation! cellulose isn't really getting degraded is it? it's just coming off. physically. you probably know more..but add heat to anything and it's always more it seems....unless you do enzymes.

  2. they're playing all alternative videos right now. like alternative like "modern rock" from the early 90's. Just say a video for Bad Religion "american jesus" and The lightning seeds. This is like when they had MTV2 samples on MTV when MTV2 first launched after school.
