Well done 👏 I have a couple of questions. Can I use methyl cellulose by itself to repair small tears without reinforcing it tengkujuh paper? Also with regards to glue removal would less acetone concentration decrease the likelihood of ink bleed through? Dr. Paul thanks for the conservation tutorial.
Michael, thank you for the kind words. Yes, you can use methyl cellulose by itself but keep in mind it's not a particularly strong adhesive and is soluble in water. It won't do a very good job bonding an end-to-end tear in paper. But it does have uses without tengujo paper for sure. Regarding the use of Acetone, if you look at the Teas chart you'll see it's less polar than water and EtOH but has greater dispersion forces. I'm not sure either of these make it a particularly good solvent of inks but it does offer different solvent properties than water or EtOH so may remove ink elements the other two solvents don't. The problem is PVA is an exceptionally difficult glue to remove once it's polymerized so you have to go after it with something effective and all of the effective solvents for polymerized PVA that i'm aware of include Acetone. Water, EtOH, and/or Bestine are not effective. I guessed that the glue we had present was PVA which is why i used the solution i did. My experience is you get ink bleed with any glue removal using solvents because solvents that are effective at removing adhesives tend to also solubilize inks. So the trick is in controlling the delivery and flow of the solvents and minimizing the total time you expose the inks to them.
@@DrPaulKosnik thank you for the useful information. Lol I'm having flashbacks from chemistry classes in college of the polarity of different solvents.
Congrats Dr Paul on getting this cover looking so good and restoration-free. I really like Bestine for such tasks with subsequent scraping the glue off. The cover looks great and no surprise you are happy with the results.
another wonderful tutorial video , Dr. Paul ! the after shots really showed off your skills . i'm amazed at how much better the cover presents . Huzzah , Sir !
in just a few days , your subscriber lists went from 2.26 k to 2.3 k ! that's an awesome 40 new subscribers ! you are growing by leaps and bounds , lol !!!@@DrPaulKosnik
Just love your channel! For me, I’m still a beginner in the Cleaning and pressing industry, the way you explain with that calm voice is such a zen experience 😅 kind regards Erik, Presskammer Germany
Looks great. I needed this video for the nuances of glue removal. Im fighting some presently. So glad you didnt lose noticeable inks. The book looks night and day better. Another wonderful job.
Thanks Travis! I'm super pleased with the results so far on this one. You just never know how it's going to turn out until you do the work. Good luck with your project!
Super glad there wasn’t any color loss when the book bled a bit.. gave me some chills watching you slowly pull apart that small corner piece. Glad the glue came off 👍 it’ll be interesting to see if this book grades out universal or conserved. Thanks for sharing!
I do not-Naptha has some distillates that can leave stains. I prefer either Bestine or Un-Du depending on the job. Here is one example: th-cam.com/video/2TTQjzx-i0k/w-d-xo.html
You sure can! Watch this video for a detailed account of one successful glue removal with CGC submission: th-cam.com/users/liveoI7hog0aaB0?si=BOKvqbJkS4Wk2YaW
Where would one find the tengojo paper that you use. I don’t need a large amount. Is there somewhere I can get it by the yard. I have been using kozo paper, it’s similar and works good, but it’s not as transparent
Ravage, i purchased mine from Talas but i did purchase a large quantity. If you tune into the live show at 7:30 Central Sunday evening, i'll ask my cohosts where they source theirs from though!

Thanks Up North! Please so far with the results. 👍🏽
Great work! Definitely gave me a cringe worthy moment when you forced the removal of the piece but it definitely turned out well 👏
Thanks! You gotta show that glue who’s the boss!
If there was any color loss, it's impossible to tell because it is so much more vibrant with all of the dirt cleaned away. I think it looks great!
Thanks Paul! Yeah I’m really pleased with this outcome!
Do you have a video talking about Naphtha?
I do not-Naptha has some distillates that can leave stains. I prefer either Bestine or Un-Du depending on the job. Here is one example: th-cam.com/video/2TTQjzx-i0k/w-d-xo.html
❤ nice
Thanks James!
Can you remove glue on spine and tear seals and get a blue label??
