Thank you for your interest in my new paper mache book Make Animal Sculptures With Paper Mache Clay.
If you have any questions about any of the projects or techniques in the book, this is the place to ask. I try very hard to answer every question on my blog, and my other readers are generous with their time and creative ideas. This is a blog where we all have fun learning together.
I also hope you’ll show us your finished projects in the comment section below.
Paper Mache Clay FAQ.
Q. Can I use Elmer’s School glue for my paper mache clay instead of Elmer’s Glue-All?
A. No – one of my readers already tried that, and it didn’t work. Rona Simon tells us that the school glue makes the clay an odd texture – like tuna fish.
Q. Do I have to use Linseed Oil in the clay? Will some other oil work just as well?
A. The boiled linseed oil will affect the texture slightly, but the clay still works just fine without it. Linseed oil is a drying oil, unlike most other types of oil. If you don’t want to use boiled linseed oil, or you can’t find it at your local hardware store, just leave it out.
Q. Do I need powdered joint compound or the kind that’s already mixed?
A. Buy the kind that’s already mixed. It usually comes in a plastic tub, and it will last for months if you keep the lid on tight. One gallon costs about $6 at my local hardware store, and that’s enough for many quarts of paper mache clay.
Q. What is “joint compound” called in my country?
A. Readers have sent in the following product names from different countries. If you can add to this list, please let us know:
- Drywall joint compound in the United States (guys in the construction industry call it mud)
- Drywall filler in Canada
- Joint filler in the UK
- Fugenmasse in Germany*
- Joint finish in Australia
Note: Ann, from Germany, gives us a different name for joint compound in that country, and some additional info. She said in her comment that
… I just wanted to let you know that joint compound in Germany is called Fugenspachtel. People from Germany should go to a so called Baumarkt and ask for Rigips (this is the major brand in Germany). Ingredients: VARIO Fugenspachtel is a high plastic-improved gypsum-based filler as per DIN EN 13963 / Typ B4. (just one of them). One will have to make a decision between about 20 different types of Fugenspachtel.
Q. Joint compound is not sold in my country. Can I use powdered gypsum or calcium carbonate, instead?
A. Several readers have tried making their clay by mixing finely ground gypsum with a bit of water to make a paste, and then using it in place of joint compound in the clay recipe. Tani say it works. However, when I tried it, the gypsum wasn’t ground finely enough and my clay ended up lumpy. I suppose that means that you will need to experiment with locally available products, and see what happens (be sure to tell us how your clay turned out). Or, it might be easier to use a commercial or “instant” paper mache product from the art store, instead. The commercial products don’t work exactly like the paper mache clay, but they may be close enough – many people use products like PaperClay with excellent results.
Q. Is the paper mache clay “archival?”
A. The paper mache clay has not been tested in a laboratory, so it can’t be called “archival.” The recipe was created to replace traditional paper mache made with strips of old paper and a paste made from flour and water. Since papers are made with a variety of chemicals during the manufacturing process, traditional paper mache methods aren’t really archival, either.( However, paper mache items made over 100 years ago often show up on eBay). If you’re a professional artist, I recommend that you do some tests of your own to make sure the finished sculptures will meet your standards. Without expensive laboratory testing, I cannot make any guarantees.
Q. Why does my clay feel so sticky?
A. I recommend that you use a knife to apply and model the clay, because the glue and flour will make it feel slightly sticky. If your clay feels too sticky, you can leave out the flour the next time you make a batch.Â The flour acts as a filler and thickens the clay, but the clay will work just fine without it. You can make adjustments in the amounts of other ingredients if the clay feels too wet without the flour.
Q. Is the clay a good art material for preschoolers?
A. I don’t think so. The clay is not edible, and spreading it over a form will be too difficult for very young kids. I suggest that you use paper clay, instead. Be sure to read the section on safety in the book, (on page 14), and read all the warning labels on the products you buy for the clay. Anyone over 8 years old should be able to use the clay safely, with adult supervision.
Q. The label on the joint compound says it isn’t safe to breathe. Should I be concerned?
A. You should never sand anything made from joint compound (or anything else, for that matter) without a face mask. Sanding creates extremely fine powder that can get into your lungs, and that is not a good thing. You can make your sculptures without sanding, just by being very careful to apply your clay smoothly. To make it even smoother, dip your knife into water and rub the flat part of the knife over the clay after it’s been spread on your form. Or, you can place a piece of plastic wrap over the clay and smooth the clay through the wrap (this makes sure that your clay doesn’t end up being too wet). To smooth the home-made gesso without sanding, use a damp brush or sponge after the gesso has dried. If you do sand, use a face mask. They’re cheap.
Q. Can I use newspaper or other recycled paper instead of toilet paper to make my clay?
A. Jennifer sent in photos of her art projects using pulp made from old newspapers to make her clay, and her projects were a great success. She used the newspaper because she wanted a rougher texture. Obviously, you will not be able to get the smooth, highly detailed look that you see in the projects in my book without using toilet paper. So – the answer is “yes” you can use other kinds of paper, but the resulting clay will have a different texture. If you’re making a very large sculpture, the newspaper would be much less expensive, and the texture might be exactly what you need. Experiment – and be sure to let us know how your experiments turn out so we can all learn together!
Remember – if you don’t see your question in the list above, please ask. Your comments are always helpful to other readers. And be sure you show off the sculptures you make, especially if you use the instructions from the book. The comments section below will allow you to upload a photo of your sculptures, and we would all love to see them.
