The trick is applying pressure to the squeegee, firmly, but gently,  pulling from center of decal out.

TRANSFERRING the decal to a ceramic or glass surface.
 


Clean the glazed ceramic/glass surface with (NEW INFO Summer 2014) a 50/50 mix of white distilled vinegar & isopropyl alcohol 91%- harder to find than the 89% but well worth the trouble. Next you will begin the waterslide decal process to transfer the decal over to the glass or ceramic surface. We recommend using warm distilled water and an electric skillet to hold about 2” of distilled water warm to the touch.

 

1. Place the decal in the water, let soak until it uncurls and before the paper backing separates from the decal. Remove from water, lay it on a clean paper towel. Let the decal rest for a bit it will help the backing lather up a bit with the adhesive on the backing. We clean the substrate while it rests.


2. Gently lay decal on the glazed ceramic/glass surface where you want it to be. For ceramics, the surface you apply the decal on should be glazed. Hold down one edge and gently slide the paper from under the decal, leaving the image on the covercoat only. Warming the ceramic/glass is also helpful. Heat lamps or a hot plate with kiln-furniture to support the ceramic or glass allows for gentle heat- warm to touch. This helps keep the decal flexible.


We try to decal the day before we fire. If not, our recommended firing schedule allows for complete drying with the very slow first segment.  Only experience / patience in handling and applying these decals brings consistent success. 

3. Now, the part that is critical-getting the water out from under the decal. First you squeegee gently but firmly starting from the middle and working out.

4. Hold tile up at eye level and check for air bubbles. Gently resqueegee if you see any. If you don’t get the decal well squeegied there will be air bubbles and holes in your image when fired. (soft red silicone squeegees- about 3-4 inches wide are available at MUDTOOLS.com.

 

Another trick to get rid of bubbles- we gently press a folded up paper towel the size of the glass and apply medium pressure with a brayer working from inside or center out.

March- 2017!  New information on tack-fuse Procedure.  We taught this method in workshops at Pilchuck Glass School and Urban Glass in Brooklyn.  People loved it so much we thought we would share.

CERAMIC Decal Firing SCHEDULE.

Ceramic decal temperature range is 1575 - 1650 F.
Kiln must be well vented, with peeps out and open, and lid cracked about 2 inches.

The base glaze that you are firing on will effect the fusion of our decals.  This is an over-glaze or on-glaze process that requires a smooth glossy base glaze for best results. 

Earthenware glazes maturing between Cone 06-04 (1819F-1926F) begin to soften slighting at our decal temperature firing range of Cone 012-010 (1575F-1632F).  The fluxes in our decals interact more on earthenware glazes. We recommend that you start testing our decals on your earthenware glazes at 1575F and look at the results.  Go up in temp 10F at a time in subsequent firings to find the surface you like up to 1650F (About Cone 010 ½). Test your glazes.

Stoneware and Porcelain glazes maturing between Cone 6-10 (2200F-2345F) do not soften at all at our decal temperature firing range of Cone 012-010 (1575F-1632F). The fluxes in our decals completely fuse to the base glaze but they tend to require more heat to reach a shine.  We recommend that you start testing our decals on your high-fire glazes at 1625F and look at the results.  Go up in temp 10F at a time in subsequent firings to find the surface you like up 1650F (About Cone 010 ½). Test your glazes.

Ceramic Decal Firing Schedule:

1.         50F-180F                              HOLD             2hrs.               Vented

2.         250F-850F                            HOLD             15min.           Vented

Note:  We strongly recommend a downdraft kiln venting system. We have Orton Downdraft vents installed on all of our kilns. Fumes need to be vented from the kiln outside and a clean oxidation atmosphere is required inside the kiln to achieve the best color results. Vent helps fight fumes and the clearer the atmosphere the brighter the colors.

If you do not have a kiln downdraft vent installed then you need to prop the kiln lid for segments 1 and 2 to vent the kiln. Then you must drop the kiln lid at the end of segment 2.  If you have a kiln downdraft vent installed just leave it on the entire firing and enjoy a fume free firing experience with consistent results with our decals

3.         200F-1200F

4.         275F-1575F-1650F             HOLD             15min.           Off


Glass Decal Firing Schedule:  Below are various Glass firing shedules

NOTE. WE HAVE FIRED AS LOW AS 1250 F. with NO HOLD.

IMAGERY IS SATIN, NOT GLOSSY AND SLIGHTLY LESS PERMANENT.

 


Glass Decal/Tack Fuse Firing      1330F

We have great success tack-fusing and decal firing in one firing if the decal is applied to the top layer of glass. At 1330F2 or 3 layers of 3mm sheet glass will fuse together, edges will fire polish and you will not have to dam the piece because the glass will not spread.

Bubbles are almost eliminated by sifting a very thin layer of fine clear glass powder between each layer of glass. You must do this to achieve a great bubble free tack-fuse.

1.         50F-180F                              HOLD                         2hr.                 Vented

2.         200F-800F                            HOLD                         15min.           Vented

3.         250F-1150F              HOLD             30min.Bubble-Squeeze     No Venting

4.         150F-1330F              HOLD                                     10min.           No Venting


Glass Decal/Full Fuse                    1450F-1475F

We have great success full fusing and decal firing in one firing if the decal is applied to the top layer of glass.  At 1450-75F glass moves and damming is required to hold the form.  If you don’t dam the glass the decal will spread and you will lose detail, density in your imagery.  This happens because of the distortion that occurs as the decal and glass stretches.

Bubbles are almost eliminated by sifting a very thin layer of fine clear glass powder between each layer of glass. This is recommended if you do not want bubbles in a full fuse.

For fusing imagery between layers of glass you are required to fire all decals on sheet glass to 1300F in a Glass Decal firing prior to full fusing.  At this point your decal fired to glass is all glass and stacking, full fusing and damming has unlimited possibilities.  It is highly recommended to sift fine clear glass powder over the pre-fired decal on glass between layers. This almost eliminates bubbles. If you have a bubble form at the surface of the decal it will create a round hole on your image. Glass powder in the hot tip.
