Grogzilla, Godzilla, Moxilla, etc

I found out about this high-grogged NON-paperclay called Grogzilla™ when I attended my first paperclay workshop with Graham Hay in Santa Clara at Clay Planet back in 2007. It is manufactured by Clay Planet and is rated to Cone 10.

What attracted me to this "traditional/regular" clay was its rough texture and the little bits of "white godzilla teeth." That was my first impression of the feldspar crystals that popped from its surface. (See close up shot below) It does look like little dinosaur teeth so I thought the name was quite appropriate.

This hand-pinched bowl was fired in Steve Davis' kazegama ash kiln at Aardvark. I applied a thin layer of flashing slip on the top 1/3 of the bowl. The rest of the bowl was left bare. You can see the ash glaze over the flashing slip as a slight grayish brown coating. At high temperatures in the kiln, the feldspar crystals in the clay break through the surface and melt into little white globules.

I enjoy this texture very much and have been using this clay in my "sandwich" technique. (See earlier post). Paperclay allows me to incorporate this "regular" clay into my paperclay sculptures.

The thing with commercially prepared paperclay is that you do not get the variety of clay bodies available as you do in traditional clays. My local distributor, Aardvark Clay Company carries the sculpture and throwing paperclay made by IMCO in Sacramento. Laguna Clay Company in Los Angeles recently started carrying their own version of Bmix + sand paperclay. Laguna Clay Company in Florida has a wider selection of paperclay (from low to high fire) but they do not ship to California.

As paperclay artists, unless you get into making your own paperclay, you are limited to what is commercially available.

In the past couple of years, I've started using the color and texture of the available clay as my color palette. That way, I don't have to deal with the issues of high fire glazes.

So .... how do I get these ordinary clay into my paperclay sculpture. My "Earthship" series employs a technique which I call "sandwiching." I don't know what is the proper name for it, but it's something I came up with because that is exactly what you do.

With the help of paperclay slip/slurry, I attach regular/ordinary clay onto my bone dry paperclay foundation. In this example, it is the "hull" of my "Earthship" series.

"Earthship 2"  and  "Earthship 3" has Grogzilla clay lumps stuck onto the ENTIRE outside of the piece. This Grogzilla clay has a high grog content with feldspar crystals in it. On high fire, the feldspar crystals "pop" and you get random pearl-like droplets (for lack of a better description). Sometimes they look like little white teeth. Maybe hence the name "Grogzilla." I really like this clay for its texture. The "Grogzilla" clay is available from Clay Planet, Santa Clara, CA.

The paperclay slip did not have any trouble holding on to the Grogzilla clay at all, although there was some surface cracking along the edges. I used more paperclay slip to cover up/seal the cracks as best I can. On both pieces, I used a Red Iron Oxide wash as a colorant. No glazes were used, with the exception of some flashing slip. Both pieces were fired to Cone 10 reduction and the sandwich technique performed and held up beautifully.

I have used this technique on either side of my pieces. In "Last Boat Out", I used Black Mountain sculpture clay on the inside of the hull. The outside rough texture was done with wet paperclay to dry technique.  I kept adding the wet paperclay to the dry foundation until I was satisfied with the thickness and shape/profile of the piece. Again, this was fired to Cone 10 reduction.

This "sandwich" technique will allow you to introduce readily available clay onto your paperclay structure.

Hopefully, you will find this discussion an inspiration to your own projects.
