About Keraflex
 
Keraflex Porcelain opens up a world of possibilities and applications previously unattainable in clay.
Keraflex
is made from ceramic raw materials and an organic binding matrix which burns out when fired to cone ten, resulting in a strong and translucent pure porcelain.
Keraflex is a world-wide patented product produced to industrial standards. Its potential is unparalleled for the opportunities it offers for the creative development of your project!
The green strength of the Keraflex sheets offers the most amazing breakthrough technology for both 2 and 3d work.
Keraflex is is very thin, very flexible when green, yet strong and very translucent when fired.
Before firing, Keraflex couldn’t behave less like porcelain. It is porcelain that you can cut with scissors, construct into 3d forms, and bond together with the Keraflex Slurry, then fire. Or you can soak the sheets in water for 20 seconds and then bend and twist and fold, let dry before firing. Or you can use the Keraflex sheets as a Porcelain 2d painting or drawing substrate.
There is no other porcelain medium, handmade or otherwise that allows such a wide range of possibilities!

Strength and Delicacy

Keraflex is very strong, thin and flexible (after soaking) when green, yet very translucent when fired. There is no other clay like it!!
Before firing, Keraflex couldn’t behave less like porcelain. Blended with an organic matrix it allows possibilities never before seen.
After firing, however, its true nature is revealed: pure, translucent, delicate porcelain that is just 0.5 or 1.0mm thick.

We have extensively tested Keraflex after firing, and found that Keraflex Porcelain is stronger than handmade sheets of porcelain (similar thickness) made by a number of artists using a variety of techniques. This is due to both the density and uniformity of the Keraflex sheets.
However, remember that the beauty of Keraflex is that it IS still pure porcelain! Pure porcelain at that thickness is delicate by its very nature. When you have fired your Keraflex Porcelain artwork, you have then created something precious and beautiful and unique. Like any other piece of fine art, care should naturally be taken when handling your Keraflex porcelain artwork.

Firing

Keraflex is very forgiving, but it is desirable to follow these easy firing instructions. Keraflex needs to attain Cone 8-10 to be fully vitrified. 
Cone 9-10 - 1280°C/2335° is preferable & some decrease in strength and translucency will be apparent at lower temperatures(Minimum 1260°C/2300°)


To Bisque Or Not To Bisque?

It is not necessary or desirable to conduct a bisque firing, even if you intend to glaze (see glazing instructions below). Because the sheets are so thin, at bisque they are extremely fragile. If it is necessary for your work to be fired in a group bisque firing, ask your technician to leave your work in the kiln until the final firing to the full temperature, so that your work is not being handled unnecessarily at the fragile bisque stage. 

Easy Firing Schedule (Manual)

Testing has shown this simple firing schedule to be very successful for kilns without a programmer. Simply fire straight up to the full temperature of 1280°C/2335°  Once this temperature has been attained, you can switch the kiln off and allow to cool as usual. It is recommended that you use cones to help gauge the top temperature. 

Note: Please note try not to fire too rapidly through the first “stage” to 600°C/1110° F. After that temperature has been attained, you can fire straight up to the full temperature of 1280°C/2335° as quickly as you wish, keeping in mind the rate that your kiln manufacturer recommends as appropriate for your particular kiln.

Easy Firing Schedule (Automatic)

First Stage: Approximately 80°C/200°F an hour until you reach 600°C/1110° F. Second Stage: Once your kiln has reached 600°C/1110° you can then continue to
fire at the same rate of 80°C/200°F an hour, straight up to the full temperature of 1280°C/2335°F (cone 9-10). Alternatively you can climb faster during this stage, (particularly if you are firing in a gas kiln) keeping in mind the rate that your kiln manufacturer recommends as appropriate for your particular kiln. It is recommended that you use cones to help gauge the top temperature, as Keraflex needs to attain the full 1280°C/2335° (cone 10) to be fully vitrified. Even if your kiln is programmed to this temperature, the location of your Keraflex work within the kiln, the amount and size of items in the kiln can affect whether your work will attain this temperature.

Handling & Storage

 The organic polymers in the Keraflex allow it to be manipulated and handled very easily due to its flexibility. Take care not to knock the corners or edges of the dry sheets against a hard surface while unpacking and working with them, as you may chip an edge. The product comes with a peel off plastic backing sheet which provides the sheets with extra protection during shipping and storage. Simply peel this off before use. 

Unlimited Shelf Life

There is no fear of the product drying out and cracking during storage. Keraflex has no moisture content, therefore there is no limit to the shelf-life. The Keraflex Slurry can get a little smelly over time, but its functionality does not change even when the use-by date has long since passed.

Basic Safety

 Please refer to the following health and safety guidelines. Please wash your hands with soap and water after working with Keraflex or the Keraflex Slurry. Do not eat or smoke while handling Keraflex or the Keraflex Slurry. Keep out of reach of children. (If ingestion occurs please refer to the safety sheets for first aid measures) If contact with the eyes occurs, rinse thoroughly with water. In the event of symptoms seek medical treatment.

Propping/Shrinkage

Keraflex is far more forgiving that other porcelains. Propping in the kiln for 3d pieces should be done as you would other thin porcelain work, however warping is far less significant with Keraflex. We have even found that flat pieces can be loaded into the kiln overhanging the kiln shelves significantly and will still shrink easily onto the shelf during firing with no warping or slumping, as long as the first stage rate to 600°C/1110° F does not exceed the recommended 80°C/200°F an hour.
As expected with porcelain, shrinkage is approximately 15-17% when fired to full temperature.

Gas/Electric

As you would expect, firing Keraflex in an electric or a gas kiln with reduction give different results color wise. With the electric firing resulting in an attractive warm white and the gas reduction giving a cooler “paper” white. In a gas kiln, you can of course achieve a higher temperature, good results have been tested up to 1300° C/2370° F. Experimentation has shown that firing this high does result in a very small improvement in strength. This slight benefit must be weighed against the higher cost of firing.
 
Glazing/Decorating
 
Some artists who work in very fine porcelain, once-fire to full temperature. If they wish to glaze, they will sometimes glaze then refire to the full glaze temperature. We do know that Keraflex responds very well to that method.
Smaller works, or pieces with smaller glazed areas, have even been successfully glazed green.
Experimentation is the key to a good result. Keraflex is a relatively new product. There are many methods that are as yet untried. We are looking forward to seeing some of your glaze results and techniques, and will upload new images and hints and tips as they become available.

No guarantee is expressed or implied by the information contained on these pages. Results may vary due to circumstances beyond our control. Testing should be conducted to determine the best firing rate for your kiln, some experimentation may be necessary in order to achieve the desired results for your particular project.
