    Good point, we all should be more careful with private jokes. I guess Mike felt like he earned it, I know I did.

    the way my good friend potsked interpreted it, was that mike was 'snickering' at the contradiction of what the book said and an opinion held by some of the members on this board. i suppose it was misinterpretated, but i don know why he would snicker on a public forum about something only you and he might understand

    The second paragraph reports the light fastness issue with low or room temperature dyeing. I wasn't aware of this before I saw it in the text book. Having their dyes fade in sunlight would obviously be a serious concern for the dye manufacturer. Hence the temperature spec. If in your case the work will not be exposed to appreciable sunlight, this may not be a problem. I don't see why some find this so offensive.

    The fourth paragraph mentions the author's acknowledgement of constant current anodizing, and it well proven virtues. None of you wouldn't know this; but early on (last summer) I took some flak from some Professionals regarding CC anodizing. Reading about CC in a textbook as authoritative as this one make me feel vindicated. A snicker is in order. Mike was in the middle of this, an innocent bystander. Since he was associated with me he also took some lumps. This earned him some snickering rights too.

    My understanding of English grammar is that a new paragraph usually means a new subject. If you are connecting the second paragraph with the fourth you are mistaken.

    I sounds very interesting, at some point I'll need to consider getting a copy.

    Room Temperature Dyeing

    The used copy of Surface Treatment of Aluminum 4th Edition, Volume 2 (1972) by Wernick, Pinner, et al, that I ordered arrived today.(only $127.00, a new set is $425.00)) Thumbing through this 1200 page heavy duty text book, I noticed this:

    "Low (room) temperature dyeing suffers from light fastness" this means that it will fade with exposure to sunlight. There are pages of experiments and data detailing this in the book. Is this why low temp. dyeing is not recommended? Those dyeing like this, will this be a problem for you?

    This book is a piece of work; tons of seriously technical info on anodizing methods from all over the world that I never heard of. Over 100 pages on hard anodizing alone. I have to find Volume 1, even if its only 355 pages.

    Also, the authors praise the virtues of constant current source anodizing, more pages of experiments and data. What a suprise (snicker)...
