Dont say how much calcium hydroxide do you add to how much water to create your milk of lyme solution.....

Correct. Because it's super-saturated. Minimum is about 1 cc per liter if you are using metric measuring spoons or 1/4 teaspoon if you are using imperial. You can of course use more, since we are making a super-saturated solution. By definition, as long as you have white precipitate on the bottom after it settles, you have a super-saturated solution, which is why i don't measure it out and didn't provide an exact measurement here.

Chemistry meets practical application meets total nerd for modern fantasy, love this channel! I’ll send my comic to you for treatment!!!

Fantastic video, can't believe a tad is an actual measurement.

Right on Jay! Good luck In getting started and be sure to check out our Facebook group the Comic Book Conservation Community for help, support, and encouragement.

This is why a collector needs a background in basic chemistry before they start Ca(OH) washing their vintage comic covers. Great video. Lots to learn or refresh one's knowledge.

Another absolutely amazing informative video! I especially liked the information on the resizing! You are a constant teacher for me. Thank you so much!😊

Great video Dr. Paul. I had decent success cleaning a tanned cover i was practicing on this past weekend using distilled water only. Thanks for making these videos.

Your info on sizing was a revelation! This explains why the more stained and worn parts of comics seem to absorb water (darken) more readily - the staining can also remove the sizing. You didn't mention what the original sizing agent is which gets remove. Is it also methyl cellulose? Is it a layer, like inks and gloss, added during comic production, or is it just a natural type of cellulose in paper/wood pulp?

Great questions Jason! I’m actually not sure what the original sizing was that was used on comic book paper. But I do know it’s internal sizing, a compound added to the pulp during the paper manufacturing.

I enjoy your highly informative videos and will soon imploy your techniques into some of my valued silver age comics. I do have one question. How do you know when to apply the resizing step and when not to? I sure appreciate it. Keep up sharing the good knowledge 👌

Typically you’ll know you need to resize paper because it will feel floppy; not as stiff as normal. Ordinarily you won’t have to do it, even after an aqueous deacidification bath. 👍🏽

What is the white capsule you add in the mixture at 14:05 while mixing methyl cellulose?

The Methylcellulose mix is good to know. Can a mixture be made for a later use or will it expire? Thank you for the tips

Can the calcium hydroxide concentrate solution be stored is something plastic like a gallon jug?

@DrPaulKosnik Great Video Dr. Paul! I've been having tremendous success with cleaning covers using your processes. However, I do see vertical comic shrinking occasionally. Where I'm I going wrong? Drying Process? Resizing Process with Methylcellulose(Does that just add bulk to the cover paper, not actually having an impact on cover dimensions or will it resize the dimensions of the book)? Or is something else completely shrinking the cover vertically ? Stumped over here...Any insight would be greatly appreciated. You are truly an assets to the Community! Thanks in Advance, Jason!

Jason, thank you for the kind words and hang in there! My experience is that drying is when the shrinkage happens, and there are some things you can do to minimize or eliminate it. Conventional wisdom is that when Golden Age comic book covers are subjected to aqueous bath, the cover usually expands from side to side and contracts from top to bottom, owing to the direction of the paper fibers, and that silver age comic books tend to behave by shrinking and expanding in the opposite directions. I looked at this extensively in several of the videos in this video series, and concluded that by controlling how you dry the page, you can essentially eliminate any shrinkage. Have a look and give it a try and let us know your results! kzread.info/head/PLnTTMDh2v7WE2DtMH6lkycyctOT-ZDZvT

@DrPaulKosnik, so about the resizing.....is that in regards to allowing a comicd to dry after it's been soaked in such a way that it won't shrink? How exactly do I dry covers and pages without having them shrink? I cleaned the cover of Astonishing Tales 169, got all the stains out, but it shrank by like 2 mm after drying.

@@DrPaulKosnik ok, thx for clearing that up, so what do you do to keep your paper from shrinking after you soak it?

When you say: "put your calcium hydroxide in a container", how much (more or less), say in teaspoons amounts if possible. I'm trying to figure this out, I ask a lot of questions but that's because in my country they never gave me chemistry class. Yes that cheap was "education" there. So all this is new to me and I want to get as close to perfection as possible to make this work.

@@JoeyRam. @TheWarningBand sorry guys i did respond, but changed my email address associated with the channel and youtube erased all of my comments. The max solubility of Ca(OH) in water is about 1.6 g/L, so i try to put about 2 grams in because we want it saturated. If you don't have a scale, that is about 1/4 teaspoon. But the whole point of using the saturated solution is you don't have to be exact--as long as there is a cloudy white powder on the bottom of the container, you know the solution is saturated!

I finally bought some Ca(OH)2 powder, but it turns out to be very low grade. It's grey instead of white like yours. I'm trying to use it anyways since most of the dark particulates sink to the bottom. However, there are still some particles floating at the top. Have you ever dealt with low grade Ca(OH)_2? Will it add black specks to my comics or have some other bad influence? Thanks again!

@DrPaulKosnik

5 ай бұрын

Sorry to hear that Jason-I would not use it! Laboratory grade is not very expensive, and mineral stains are very difficult to remove from paper. When you make the saturated solution, the part you pour off the top to use in your aqueous bath should be 100% clear-indistinguishable by eye from water.

No way in a million years would I have figured out how to make the methyl cellulose solution, do you or can you make a large batch so you have a ready supply on hand? will it hold up over time?

@DrPaulKosnik

2 ай бұрын

It holds up just fine as long as you store it in an air-tight container. It reacts with CO2 in air to form Calcium Carbonate, which is not a big deal but doesn't work quite as well as the Ca(OH) for our purposes. Let us know how it works out!

I didn't get to my resizing bath for a few days after I mixed the 1% methly. The 1% solution I mixed now has a clear gel looking compound at the bottom of the container. Can thos still be used, or should I discard it?

Biggest takeaway: a tad is an actual measurement!😅

It is hard to dissolve that methyl cellulose in 100 mL of hot water! Why not start with 400 mL of water instead of adding it in later? Surely it is easier to get the powder to dissolve into 400 mL than 100 mL.

@@DrPaulKosnik I have to admit, it did seem easier to dissolve in the powder as the concentration increased. Counterintuitive indeed. Maybe it has to do with the change in properties like viscosity or surface tension as the solution thickens.
