Issue #84 - Kiln Wash Application

Hot Out of the Kiln

July 2015

Although the summer heat is not that bad, the lack of rain is really showing an impact.

We actually did have a few rainy days this last month, and it was very much welcomed.

Then you see images of all that precious water running through the sewers and into the ocean.

You would think in this day and age what with all the knowledge and programs, that someone could find a way to capture and reserve all this rain.

The Fall 2015 issue of the Fused Glass Projects e-magazine is complete and has been sent to be proofread before becoming public at the end of next month.

I have been working with clay and making some molds for unique glass fusing projects, and am thinking about doing another webinar in the near future on making clay molds.

Let me know if this might be something you might be interested in learning.

The Summer 2015 issue of the e-magazine is currently available and can be purchased by clicking here.

Until next month…keep it hot!

Kiln Wash Application

Kiln wash application can be achieved using a brush, haik brush, or a sprayer.

Kiln wash is still a necessity in glass fusing and is used to protect your kiln shelf, kiln and molds during the firing process.

The main purpose for this material is to prevent glass from sticking to any items when firing items inside a kiln.

It comes in a powder form and is mixed with water according the manufacturer’s instructions to achieve a liquid form, which is then used to coat items before firing.

The consistency of the mixture should be similar to skim milk.

Several even coats need to be applied and dried to protect the shelf, floor, walls or mold during firing.

A blow dryer can be used to speed up the drying time between applications.

I have generally applied the wash with a haik brush, but find that the tiny hairs of the brush get stuck in the mixture on my shelf or mold and have to be picked out.

Using a sprayer works until the nozzle gets clogged and the bottle needs to be tossed.

If you don’t have kiln wash to prevent glass from sticking to the walls or floor, you will have a number of problems:

Glass could become stuck, which will make it had to remove without harming these areas.

The glass will have to be ground or chipped out of these areas, which will destroy the smooth surface of the kiln brick.

Have you been wanting to learn the hot craft of glass fusing, but don't know where to begin?

Whether you enjoy watching movies to learn the techniques, or having a book to refer to as you learn, these learning tools will assist you in your progress.

If you don't have access to glass fusing classes, or want to learn some of the techniques that are not generally taught at these instructional settings, look no further.

I am trying to add new and exciting information all the time, and these learning materials are the newest items added to the site to help others learn glass fusing procedures.

TIP - If downloading any of the downloadable movies, keep in mind that they are very large files.

If you purchase and want to download any of these large files, you might consider using a product like the Free Download Manager.

It is a free product that needs to be downloaded and installed on your computer.

It will increase the download speed and decrease the time required to download the product.



.One of your readers mentioned that she had been using a red glass she had found in her kiln and it turned black. Red glass, by its nature, or composition if you'd rather, is tricky. Rarely it will turn lighter, but more than not it turns darker.

Red glass is often made up of cadmium, selenium, gold oxide, copper, and sulfur among other elements. Depending upon its composition, the red can be affected by temperature, humidity and even the introduction of additional air in the kiln during firing or even other glasses that are fired at the same time which might gas certain elements in the firing that affect the final color of the red.

One solution to keep Spectrum and Bullseye reds red is to keep the red from being held at a high temperature for any length of time. Spectrum, for instance, suggests that red not be fired above 1200 degrees Fahrenheit because the molecular relationship between the elements that make up red changes and can result in colors ranging from yellow to brown to black. Re-annealing red can also cause color changes as the balance between the elements that make up the glass are re-arranged in the re-heating of the glass.

I know that the glass used was found glass--drinking glasses-- but the principles are probably the same.

    Preval Spray System

    There has been a lot of buzz on Facebook about using the Preval Spray System, so I decided to try it myself.

    I found the product at my local Home Depot for only $4.95, and they had them readily available for purchase.

    This is a spray gun that can atomize just about any liquid.

    It comes with a small 6 ounce bottle jar and the power unit.

    There are no other items required.

    I mixed up some kiln wash and filled up the bottle jar.

    The bottle is then screwed to the bottom of the power unit.

    I then attempted to spray the kiln wash onto a mold.

    When it worked, it was great, but most of the time, I got more kiln was on my hands from the leaking bottle than on the actual mold.

    I was not at all impressed with the application, but maybe I received a faulty product.
