9.8, white pages, pedigreed. yep, nobody around here cares about those things are you saying i didn't show enuff love for the last 9.8 you showed me? shame on you for holding out on us. I figured you to only look once at it Billy. Ricky'd like the condition and Pons woudn't like that he couldn't leaf through it The man knows his geeks Indeed I do Billbo!! I'm gonna be seeing them in 3 weeks Enough of this geek love-fest! Back on the short bus! A nice, clean copy of this oddball giveaway -- except for the tack holes. Jack

Keep digging i don't have to dig very hard If Super Duck counts, I could keep us busy (I hesitate to write "entertained") for a while. I like the cartooning on "Red" Rabbit. (He's not actually red? He's a communist sympathizer?) I don't know much about them, but GCD lists Sam Singer, Bill Newton and Stan Louis on the few indexed issues. Little doubt about Little Eva, eh? Jack Oof! Quite an eyeful of SB material Jack!!! Sometimes it comes right up and pops you in the eye! Jack (Little Eva hoarder)

I don't know about communist sympathizer but it says Uranium on the cover ... #12 -- yet another obscure element cover! Who's selling? Jack

Bill Woggon doesn't have a short bus seat either True -- more the subject matter than the artwork. He did most of the interior work too. Maybe he should be Bill WoGGAn. JPS (surely there's something lamer in the pile)

I haven't looked at this thread in ages! Jerry Robinson on the short bus? Not while Kasco Comics 2 is around. Where else would I learn about the Kasco Beatsall Dairy Plan? Jack

#21 -- very nice copy. I have one but (ironically) it's much more raggedy. Can you tell whether it's a George Kerr or Mo Gollub cover? Almost done with the series? Jack (I haven't had time to check the gold board in ages!)

Thanks, Jack

Outsiders 2003 #1-35 (some indivi issues avail) Oz (Caliber) #14-17, 19,20 Oz Straw & Sorcery #1-3 Oz Squad 1992 #2 Oz Squad #4-10 Oz Squad Special (Millennium) #1 Little Oz Squad via PM I hope I have the right thread. Jack

GL 1990 132, 134-135, 171-179, 181 How do I read the price? If it's $1.50 for the whole set, I'll take them all! It's really $1 each for 132-180 and $1.50 for 181, right? Thanks, Jack

You were missed. There was even a thread about it (thumbs u Yikes. I hope people spelled "scoundrel" right. Jack

Wow -- there can't be many Golden Age stories about polyesters! Any good chemistry specifics in the story? Thanks for posting. Jack (back from a couple of weeks traveling)

I'm going back and forth about whether storing the boards alone would be a proper test. The problem is that acidic pulp paper autocatalyzes its own decomposition. That is, the volatile acids, especially acetic acid (the "old comic book smell" that some collectors love is mostly acetic acid and mildew) causes further breakdown of cellulose, leading to crumbling and yellowing. If there is no pulp paper present to produce acetic acid and start the cycle, the board alone probably won't break down as quickly as it would with the paper present. There is some good information at the Library of Congress site Index If you want to see actual headspace measurements, see here and here. With those references, I'm sure we've gotten too technical for this forum. Good luck! Jack

That's puzzling -- usually the technical wikipedia pages are pretty accurate. I wonder what the writer meant by defining the pKa of CaCO3 that way. It doesn't have a proton, so it doesn't have a pKa. JPS

Yes sir, I can. Drew's pH level of 9.5 to 9.75 came from memory, and when I asked him what his reference was during our phone conversation today he couldn't remember where it came from. I mistakenly gave the pKa value as the pH level. Thanks for your help with this. :thumbsup: ? "Carbonate has two pKa values, 6.4 for carbonic acid <-> bicarbonate and 10.3 for bicarbonate <-> carbonate " Neither pKa = 9.0. JPS

I was going to give up on this thread, but it's starting to make sense! I'm glad to see that you were able to communicate. Statements above that are not quite correct: "the pH level of calcium carbonate is 9.5 to 9.75" and "calcium carbonate has a pH level of 9.0." I'm not sure what that means, since pH is a property of an aqueous solution, not a solid. The pH of a solution depends on the concentration of acid or base in the solution. Whoever doesn't want to read technical details can skip this part. What matters is the pKa (equilibrium constant) of the acid or base. Carbonate has two pKa values, 6.4 for carbonic acid <-> bicarbonate and 10.3 for bicarbonate <-> carbonate If I quickly did the calculations right, a one-molar solution of calcium carbonate (it's not really that soluble) would have a pH of about 12.2. A one-molar solution of calcium bicarbonate (HCO3- from adding one H+ to carbonate) would have a pH of about 10.4. Can you tell me where the numbers 9.0 and 9.5-9.75 came from? That would be close to the pH of a 0.1-M solution of calcium bicarbonate. While I'm waxing technical, the Lewis acid/base description -- I don't remember who brought it up -- has almost nothing to do with this discussion. This is all Brønsted-Lowry acid/base. The coatings you're discussing almost certainly have a binder in addition to calcium carbonate, or it would simply flake off like chalk dust. Jack

If you don't have one, you owe it to yourself to read this book. It's hard to tell whether it's serious or intentional parody. Jack

I'm not sure how to read that -- if you'll break them out, how much to add 23, 31 and Plus to my burgeoning pile? Thanks, Jack

It was a joke. We really didn't think we were going to have to defend ourselves where the correlation between Aluminium and Alzheimer's disease is concerned. However, now that we understand the ground rules, we will refrain from making any off-topic statement which can lead to an argument. Sorry, I missed the irony. JPS

Wow**2 JPS

According to Mike's study there was no change in the pH level of the E. Gerber boards at all. Therefore, either Mike's data is incorrect, or the E. Gerber board does not absorb any acid even after 2 years of use. ... Wow. Jack

Actually, we recommend against the use of Mylanta because it contains Aluminum hydroxide and may contribute to Alzheimer's disease. I just noticed this thread yesterday but haven't read it all the way through. Fascinating and at times surreal. Has anyone done the grind-up-and-titrate experiment yet to actually measure the buffer capacity? Your understanding of biochemistry and cause/effect is about as deep as your understanding of pH buffers. According to The Alzheimer's Society, the overwhelming medical and scientific opinion is that studies have not convincingly demonstrated a causal relationship between aluminium and Alzheimer's disease. Yes, I know there there are some people still clinging to the belief that aluminum exposure "causes" Alzheimer's disease, but the connection has been debunked. Some people believe in astrology too. JPS

Howdy, Howdy Doody! Nice copies. If you try posting any CCA-stamped Dells, you're in big trouble. Jack (just flew back from Wisconsin and... say it together...)
