Lithography is a unique art form where artists draw with greasy materials on a stone. The stone is then chemically treated to establish where water and ink will go. The drawing is replaced with ink, creating a beautiful print. This process allows for detailed and subtle artwork.. Created by The Museum of Modern Art.

- At4:13, he mentions a towel called a cheese cloth.
What is that?(14 votes)
- A cheese cloth is a smooth woven piece of fabric that is used for making cheese (or broth, or straining yoghurt etc.) but which is also used outside of the kitchen in lithography! You can read more about it here: http://en.wikipedia.org/wiki/Cheesecloth(13 votes)
- @4:14He says that he adds more gum arabic "...so we don't run the risk of having too much acid on the stone." What would happen if there was too much acid?(9 votes)
- If there was too much acid left on the stone it would be transmitted onto the paper, and the acid would eventually destroy (on a very small, chemical level) the paper, causing it to deteriorate and thus have a shorter life than it could have if there was no acid at all. Thinking about the longevity of a work is very important, which is why so much time is taken to remove as much of the acid as possible.(12 votes)
- How did they develop this process? It has so many steps!(13 votes)
- I think it started when a scientist was experimenting with printing techniques and quickly wrote a list with two things he had at hand, a wax crayon and a stone?
I guess it got very refined.. interesting process(4 votes)
- What is "Gum Arabic" made from?(5 votes)
- Gum arabic is a natural gum made from the hardened sap of trees native to the Middle East and parts of Western Asia. Food manufacturers often use it as a stabilizer in food and drinks that are designed to have a long shelf life, and the soft drink industry is one of the largest consumers. The gum is also used as an additive in art products and cosmetics, and it has tradionally also been important part of ink-on-paper printing. Basically any tasks that requires binding different substances together or holding ingredients in a stable suspension can benefit from the addition of gum arabic.(11 votes)
- I notice the stone is very thick. Is this usual? What is the benefit of this, when it seems like you can make so many slabs from that one thick slab?(3 votes)
- I've never done lithography, but I've done other forms of print making. Any time you make a print, you run the plate, or block, through a press, with a lot of pressure. The last thing you want is to break it. I imagine, that's why the limestone is so thick.(6 votes)
- At3:44- what if you do disturb the drawing? Would you be able to fix it, or would you have to start over?(4 votes)
- Do you have to use limestone, or can you use a different stone for the lithographic process?(2 votes)
- While Alois Senefelder's original process used limestone, other materials, such as zinc plates or polyester plates (a lá Prof. George Roberts), can also be used.(4 votes)
- Is there a way to erase a drawing on the stone? Or is it just one drawing, that's it? Is there a way to fix mistakes?(3 votes)
