A few years ago I experimented with different types of paperclay (air dry and fired clay) on canvas, drywall – almost anything I could get my hands on. I have used paperclay (firing in a kiln) to repair scupture and relief with success. I felt it was a subject that needed revisiting as paperclay is being used today for large sculptural works for thinness translucency and strength. I need to distinguish the 2 main types of paperclay – air dry ( no firing required) and fired paperclay in a kiln. I have used both. Non firing paperclay is excellent for sculpting models for a mold, whereas I use fired paperclay to repair greenware and bisque sculpture and releif.
Here is some examples of Air dry paperclay on Canvas and drywall:
The recipe for Air dry paperclay is as follows:
Paperclay: In a bowl combine
3/4 c. flour
1/2 c. cornstarch
1/2 c. salt
warm water – mix with hands and knead until consistency of clay.
Paperclay recipe #2
1 pkg creative paperclay
2-3 tbsp wallpaper paste
2-3 tbsp water
cut paperclay into chunks add water and paste. Mix and knead with hands until consistency of toothpaste let dry overnight. seal in ziploc bags
Paperclay Recipe for kiln firing methods:
You can use a variety of different papers and clays to get the effect you want such as stoneware or porcelains. It is by experiment and your favourite clays. The recommended paper to use is newsprint but any paper (with the exception of gloss papers) will do. Thus ancient paper mixture allows the clay body to open up, lighten the weight and add strength. The recipe for this process is simple and easy – start by shredding the paper ( in a shredder works best and is faster than by hand) Soak overnight at least 24 hours. Next with a blender or drill with a mixing bit attachment mix the soaked paper until a thick paste consistency. Add your clay in powdered form — 60 parts powdered clay to 40 parts paperclay.
For repairs on bisque or greenware: Add 1part magic water, 2parts clay mix until a slip consistency. next add 1 part toilet paper or tissue paper and mix until a smooth paste. glue the broken pieces together or with a small paintbrush paint the cracks with the mixture. let dry and sand with fine sandpaper **carefully***.
Magic Water : used by sculptors and potters to adhere wet clay together after scoring the pieces.
3 tbsp sodium silicate
1-5 tsp soda ash
1 gallon water
Spooze: (use: as above)
1/3 Karo syrup
Paperclay technique allows ceramists to create large thin forms to achieve translucency or luminous sculpture such as in porcelain. Reference: & for more information See The Art & Craft of Ceramics Techniques, Projects, Inspiration by Maria Dolors Ros i Frigoloa
