A Week With Li-Qua-Che 4.0

Li-Qua-Che, Brad Ford Smith
This is our fourth and last Li-Qua-Che project. This time we are creating a small one piece mold that will be used to cast both sides of an object. The photo above shows the oil clay model of a 4" nubby club just before pouring on the plaster.

The nubby club is framed by plastic retaining walls to create a form to pour the plaster into. The model and walls are lightly sprayed with PAM as a release agent.

Here is the plaster mold after hardening. It still has the oil clay club in place which came out easily with the help of a pick to grab the oil clay and lift it out.

The mold is cleaned with a little naphtha to remove any oil residue. Now is also the time to clean the mold of any surface anomalies. 

Li-Qua-Che, Brad Ford Smith
The mold is filled with Li-Qua-Che. After waiting 5 minutes the Li-Qua-Che is poured out leaving behind a 1/8" leather hard layer of Li-Qua-Che in the mold. In the photo you can see the Li-Qua-Che shell is pulling away from the plaster walls as it dries and shrinks.

Li-Qua-Che, Brad Ford Smith
Here are the two cast sides pulled from the same mold. In theory these two sides should fit together perfectly. But due to the shrinkage ratio of the Li-Qua-Che, the edges shrink back more than the surface areas. This creates edges that are thin, pointy and uneven.  Keep that in mind when building your model. All edges need to be extended so that in the edges of the finished casting can be sanded back to create smooth even joins.

Li-Qua-Che, Brad Ford Smith
So, here is the nubby club glued together and the seams filled with spackle. Note that the surface shows finger prints and boogers found on the original oil clay model. If you don't clean up the model and/or clean the surface of the mold, you'll be cleaning those finger prints and boogers off every casting.

Well, That concludes our week of playing with Li-Qua-Che. I haven't even touched our projects that used two part molds. But I think that's more than enough posting about this topic. Any more and I will need to open an online Li-Qua-Che store, and that would expose me to way to many questions pertaining to doll heads.

A Week With Li-Qua-Che 3.0

Due to the Dallas Art Fair with 83 galleries, multiple lectures and a few side art events, plus posting about the art fair for Art and Seek, these last two BFS blog posts about Li-Qua-Che had to be postponed until this week. Anyway, back to fun with liquid paper mache... Size does make a difference.

Li-Qua-Che, Brad Ford Smith
In our past Li-Qua-Che projects we made large tiles that had issues with de-molding, warpage and strength. In this project we scaled down the tile to 5"x 8". We also dropped the idea of incorporating open areas/holes into the design. Above is our smaller finished tile after curing over night. You can tell by the surface that it still needs some light sanding with 0000 steel wool to smooth it out.

Li-Qua-Che, Brad Ford Smith
This photo shows the plaster mold and the back side of the cast tile. The compactness of this tile design avoided issues of warpage. The tile also held up to the stress test of being dropped on the floor. (An accident that we will take credit for doing)

We did notice that the edges of the tile were a bit ruff. With that in mind, when designing a one piece mold, the model should be fabricated a little taller so the ragged edges can be sanded down to form a straight, smooth edge.

Discovering Free Dallas Art Fair Tickets

The fifth annual Dallas Art Fair is just around the corner, and with 83 galleries in this years line up, 40 of which are first time participants, I am starting to get really excited to see some new and exciting artwork.

While perusing the local media coverage for this event I discovered two wonderful things which I am very excited to share with my BFS Blog subscribers. First is the new art and entertainment website CultureMap. They have been around for a while but I just found out about them.

The second discovery is that CultureMap in their post Enthusiasts Experience Dallas Art Fair for Free on Professionals Day posted a pass code that allows you to purchase free tickets to the Dallas Art Fair!

NOW you have no excuse to miss the most important art event in the DFW metroplex!

A Week With Li-Qua-Che 2.0

Li-Qua-Che, Brad Ford Smith
This post continues with our week long experiments with Li-Qua-Che. The photo above shows design model #2. The cork sub-straight has been gessoed and oil clay has been added to smooth out and build up the surface.

Li-Qua-Che, Brad Ford Smith
This is the plaster mold pulled from the above model. It has cured in the oven over night. The mold measures about 12" square.

And here is the finished Li-Qua-Che casting. The Li-Qua-Che picks up every detail including scratches and finger prints. So make you model as smooth as possible, and then smooth the walls of the plaster mold as well.

There was some difficulty getting the casting out of the mold, but with the help of a small pallet knife, it finally came free. The real issue was that while the casting was sitting on the table curing, it began to sag and warp.

Summing up our experiments so far, this material is surprisingly strong, but it has size limitations. It will not hold its shape if casting a single sided tile over 10" in size. With that in mind we'll move onto designing two more projects; a smaller 8" tile, and an object that is similar in proportion to a doll head.

Here's a link to some more Li-Qua-Che tips at Konittajo's Playhouse.

A Week With Li-Qua-Che 1.0

Li-Qua-Che, Brad Ford Smith
My good friend and fellow artist Kent Peaslee came down from Chicago to spend a week with me playing with Li-Qua-Che. It was like creating our own artists residency.

What is Li-Qua-Che? Basically it's a liquid paper mache that has been refined to the point that it looks more like porcelain slip. It's designed to make slip castings of things like doll heads.

During our week of investigation, we played with a lot of casting techniques, learning a lot and pushing the product to its limits. Over the next four BFS blog posts I'll be reviewing projects that focus on casting a tile from a one piece mold.

Li-Qua-Che, Brad Ford Smith
Our first project was to create an 8"x11" sculptural tile that incorporates an open space in the center of the tile. Above is the original design drawing.

Li-Qua-Che, Brad Ford Smith
In this photo we are building the sub-straight for the tile using sheets of cork. We then covered the cork with oil clay and added some details. 

Li-Qua-Che, Brad Ford Smith
This is the plaster mold we pulled from the model. The mold was placed in a warm oven to speed the evaporation of the water from the plaster. Be careful doing this as the plaster will go through thermal shock if it gets too hot too quickly or cools down too fast.

Li-Qua-Che, Brad Ford Smith
Now for some casting. Here the Li-Qua-Che has been poured into the mold. After waiting 8 minutes it was poured out of the mold. What remains is a 1/8" thick wall of Li-Qua-Che (The gray stuff).

Li-Qua-Che, Brad Ford Smith
The Li-Qua-Che shrinks 4-7% as it dries. Just like slip casting with ceramic slip, it pulls away from the walls releasing itself. In theory, as long as there are not undercuts, the casting, after 30-60 minutes should just drop out of the mold. Unfortunately our design with the big open space in the middle of the tile created a large solid form that the Li-Qua-Che locked onto as it shrank. Getting it out of the mold caused cracks in the casting. After curing, the casting simply fell apart at the weakest structural points.

The Digitally Drunk In NYC


As I walked the streets of NYC back to the 80s, watching the young hipsters intoxicated on Jagermeister and cocaine, stumbling like helpless puppets into the on coming traffic, I was not surprised to find the late night streets of SoHo speckled with blood and teeth.

Today, texting is the preferred drug. In my latest visit to NYC, I saw people walking purposefully from point A to point B, never looking up from the palms of their hands. Its like watching some new religious cult who beleieve the world contained in the palms of their hands will protect them from the throbbing masses, bike messangers, and feed up taxi drivers.


They are the digitally drunk. Obsessed with being in touch, on top, and so with it NOW that NOW is to late.


These photos are dedicated to them. Look up people. See the drama above your heads.

...And look both ways before crossing the street.

Secret Tales About Anonymous Portraits



The Portrait Secrets Salon is the creation of Amy Walton. She has combined two of her favorite things, collecting anonymous portraits and story telling, thus creating an entertaining literary event that is packed with home spun culture.

She began collecting portraits years ago, finding them at flea markets, thrift stores and under random rocks. These anonymous paintings, drawings and photographs cover the walls of her living room and a few random strangers now adorning in her bedroom.

When asked about the portraits, Amy would reply "I don't know who they are, I simply like them".  Over time this response left Amy feeling flat. It didn't convey the playfulness and affection that she felt for her collection. So she decided to recruit a few friends flesh out her collection by asking them to write short histories about some of her portrait pals.


For her second gathering of the Portrait Secrets Salon, I was one of seven people who had the pleasure of giving voice to one of the canvas personalities. I recounted the story of Susan and the Plumbers Dilemma. A coming of age story with drama, passion, and trouble with the pipes. It surprised me how much fun it was to write this little narrative, to dabble in the romance genre just for a bit, and to create something that was simply fun.

Check out the Secret Lives Of Our Portraits website where showcasing some of the portraits and their stories.
