Mumbles Posted September 13, 2007 Posted September 13, 2007 I still don't believe Eric's Results. I had been wishing to do my own independent analysis, but it hasn't happened. If his results were true, no color besides orange or yellow would even be possible. I can personally verify that I can produce a nice blue and purple with the standard chinese perc.
tentacles Posted September 13, 2007 Posted September 13, 2007 mumbles: the standard chinese perc came out pretty good, here's the second version of the notes with that one in it: http://www.bentspoonsystems.com/MaterialsR...ratenotesV2.pdf
Mumbles Posted September 13, 2007 Posted September 13, 2007 My main gripe is that he's too close to the saturation point of water with perc. If it cools down even 5 degrees, there is going to be a reasonable amount of perc in the "insolubles". I would love to see the results if he used 300g of perc instead of 600 in 3000mL water. Thats about 50% max solubility. You'd be certain not to lose much as so called "insolubiles" and gives a bit of a safety margin for making sure it's truely insoluble. If it's insoluble, it's insoluble no matter the concentration. I wasn't aware he did a Version two, but it does look more reasonable overall.
tentacles Posted September 13, 2007 Posted September 13, 2007 Mumbles: not to hijack this thread, but I think he also tried to dissolve the insolubles again in clean water, and almost nothing would dissolve. His tests aren't conclusive, certainly, but point to the need for further investigation.
Mumbles Posted September 13, 2007 Posted September 13, 2007 I know of someone he gave some of the insolubles to. As of this date, I don't think he's tested it though. It was from the first test with the 10-15% insolubles or whatever. HP-140 or something I do believe.
