HydroGlaze is an overglaze product that allows for creative, easy-to-apply decorative decals through hydrographic and screen printing techniques. Once applied the overglaze can be re-fired to its desired temperature (^6-^10) creating a permanent decal. HydroGlaze provides ceramic artists with a simplified way to decorate 3D forms and textured surfaces with striking precision. This process broadens the possibilities of traditional decals and makes ceramic decoration more accessible to creators.

Follow these instructions to achieve optimal results when applying HydroGlaze.

Materials Needed

  • HydroGlaze

  • Hydrographic Film

  • Screen Printing Supplies

  • Water Tank / Dams

  • Bucket of warm water

  • Protective Gloves

  • Dish Soap (for cleaning)

  • Vacuum Table (optional)

Before You Begin / Things To Consider…

  1. Water Temperature: Cold or room temperature water is preferred for dipping. Hot water causes the film to expand rapidly which can pull apart the decal.

  2. Depth of Tank: The water tank should be deep enough to submerge the ceramic object into it easily. The force of the water pushing the decal against the ceramic surface is crucial.

  3. Size of Water Tank / Size of Decal: The wider the tank the more room for print to expand. Placing a small print into a large tank leaves too much room for the film to expand and could cause the decal to break apart. (This can be addressed with dams that contain the print in a designated space or with a smaller dipping tank)

  4. Work Space: Handle the hydrographic film in the studio with care, as it is highly sensitive to water. Even minimal contact with moisture can dissolve the film and damage the roll.

Application Process

  1. Stir the HydroGlaze:
    • Start by thoroughly stirring HydroGlaze to ensure all ingredients are evenly mixed.

  2. Cut the Hydrographic Film:
    • Cut the hydrographic film slightly larger than the design.

  3. Printing with HydroGlaze:

    • The hydrographic film is slightly embossed, print on the side with less texture.

    • Secure the hydrographic film onto the printing table (with tape or vacuum table) to prevent it from sticking to the underside of the silkscreen. If using tape, be sure the film is taut before printing.

    • Place an adequate amount of HydroGlaze onto the silkscreen, then print directly onto the film.

  4. Transfer Film to Water Tank:

    • Carefully pick up and place the printed film in the water tank, print side facing up. Allow the film to absorb the water for approximately 20-30 seconds.

    • Be sure to print and dip in the same work session if the ink dries to the hydrographic film the process will not work.

  5. Submerge the Ceramic:
    • Slowly dip your ceramic into the design, allowing the print to stretch around the form and textures.

  6. Rinse:

    • Gently rinse the piece with warm water to remove the film residue. Do not scrub the surface. I recommend submerging the ceramic into a bucket with warm water and gently swirling. This takes roughly 15 seconds, depending on how warm the water is. You could also use a gentle mist from a pressurized sprayer or under the tap of a sink.

    • After rinsing the surface, there should be no noticeable sheen or tackiness left from the residue. Check for any remaining residue, by gently touch an area that is free of print. Avoid making contact with the printed areas, as the ink is still be wet.

    • You can then move directly to the firing stage. If left out the ink will dry and can still be fired later.

  7. Firing:
    Re-fire to the desired temperature (Cone 6-10) to permanently adhere the decal.

Following these steps will help you achieve a beautiful finish with HydroGlaze creating a durable design.
