Rag in Rag board

[nona powers]

I can't find the topic now, but finally have an answer on the topic of what rag board is made out of. I didn't want to be wrong so asked for confirmation. It's made from cotton linters, not rags. It hasn't been made from rags for years except for a few specialized papersnot used in the framing industry. The linters are fibers from around the seed when the cotton is milled.

Thank you Nona, that was the answer I had pretty much expected. I think that in the future I will close down my hearing channels when the rep who told me the BS comes in.

[QB]Tell us, Nona, exactly what IS papersnot? It sounds really disgusting! HAHAHAHAHAHAHA

I thought about that myself, but didn't have the gumption to say it to Nona Powers! graemlins/shutup.gif

I wonder if that is anything like tape boogers. :D

Henestly, your all like a bunch of kids, have to keep an eye on you all the time. Settle down now!

Each and every finger has a mind of it's own and none are connected to the main terminal in my head. I type it up then look and see what I've done and cringe. I liked the cutting chenille with a wozard also. Life is an adventure and so is this forum. One never knows what one will get.

I'm moving Ellen to the head of the class where I can keep a close eye on her or there is no telling how low this forum will go!! Behave Ellen....but not too much.

tongue.gif Papersnot was the first thing I too noticed about this column, but I was afraid to mention it. I must be more courageous.

I still don't understand how alpha-cellulose is as good as rag.

[lyoncat]

well, I do not know all the specifics, bu I DO know that the cellulous in rag is not nearly as acidic as pulp (wood) made matboard. I see it on the few samples I still carry as regular (wood-pulp) matboard. They have "browned" on the edges where the bevel would be.
If anything, I explain to the customer that is the experience they would have with a wood-pulp matboard. The edges would turn brown/
I also explain how much of a design element this is. Those white lines from the bevel make an impact on the job!!!
It is wise to venture towards the few color-cores available to distract from the design.
I hope that some designers read this to know we need more color core, especially in the muted tones.
Well, I am on a rampant now, so I should stop, and sing to the song that is on the radio instead.

Jerry Vandergriff posted an interesting concept on the HH and I included an exerpt from his post here for you to read. It is a little scientificky (my new word for the day) but it points out a characteristic of Alpha Cellulose that I was not aware of. It may prove interesting to some of you.

BTW, it was in reference to the possibility of bleaching of art prints which may be caused by the buffers used in AC matboards.

Alpha Cellulose is not only present in AC boards but is a constituent of regular and rag mats also. Alpha cellulose is the fiber material present in all cellular structure. As long as paper (ie Mat board) contains materials made from once living materials it contains alpha cellulose this includes cotton linters which are essentially pure cellular material from the cotton
plant that contains no lignin. Alpha cellulose boards can be purchased buffered and non-buffered as can almost any high quality mat board. So the
question isn't if the AC is causing bleaching it's if the buffering is causing bleaching.

Calcium carbonate (normally used as a buffering material) is not normally considered a "bleaching" material. When CaCO3 reacts with acids the reaction products are carbon dioxide, water and disassociated calcium ions and anions
depending on the acid in the reaction. Say for instance that hydrochloric acid reacts with the calcium carbonate, besides the reaction products
mentioned you will also have positively charged Ca ions and negatively charged Cl ions. The calcium and chlorine may well react and create calcium chloride (CaCl2, ie Ice Melt). Bleaching is normally associated with chlorine and peroxides due to the high reactivity of chlorine and oxygen with many organic materials. The other thing that causes bleaching is UV light, which we all know, and regular visible light although it can be slower.

It may make more sense if you go to the HH and read the entire post including those that led up to his posting.

OK. How do I find Jerry Vandergriff's article on Hitchhiker. I could find no "Search" option. redface.gif

I am really interested in this.

Rag board is made from a plant. It’s made from the cotton linters from around the seed after the cotton ball has been removed. If you ever saw the example rising used to have in their booth, it comes out a dirty brown color and has to be bleached and the impurities removed, then it’s made into boards.

Wood pulp is also a plant. For C/P conservation/preservation framing the lignin and impurities are removed, it is bleached and made into a board.

Regular wood pulp board is unpurified, still contains lignin and should not be used for C/P framing because it deteriorates over time and damages paper it’s next to.

Both wood pulp and rag are Alpha cellulose.
Both are equally recognized as C/P framing materials and are completely interchangeable, it is up to the framer to decide.

The Library of Congress recognizes purified, or lignin removed wood pulp boards as acceptable for C/P framing.

Many museums and conservators recognize purified wood pulp bards as acceptable for C/P framing.

FACTS standards for paper and matboard lists rag and purified wood pulp as equal and interchangeable in use.

Some framers prefer rag and it’s fine to use it, but actually, it has no advantage.

Or you could just ask me!

I agree with Nona, I agree with Nona nah,nah,nanah,nah.

My next diatribe will concern Lignin if I can ever figure out it's chemistry, but guess what its found in all types of plants too.

BTW Chemistry is not a concept.......
I always say better living through chemistry.

Thanks guys! This is exactly what I wanted. tongue.gif
