Firing Silver Stain

The samples were fired in an electric kiln over a 2 hour period to 1100° F and held at that temperature for 5 minutes.

Samples are fired "face up"

BEFORE: Unfired samples

AFTER: Fired samples (before removing clay residue). Note the color change of both the clay and the glass compared to the unfired samples above.

Notes about Airbrushing Silver Stain

 APPLICATION NOTES:
At the time of application the following observations were made. Ease of straining and applying paint was noted. The amount of gum was judged by stippling with a white hog stippler.  If no comment appears about a particular attribute on the chart below it indicates that the performance was average for the group

Applying Silver Stain with an Airbrush

Use an eyedropper to transfer the paint.
Add paint to the airbrush. I use a Paasche H-5.

Apply the paint in a gradation to the test samples.

Number the samples. This stain is Reusche 1382.

Remove the samples from the easel.
