This is a clear glaze I spray on top of the colored Glendale Community College Gloss glaze, to give the surface a bit more depth. The glaze recipe is also from the college.

  • Is this recipe good stand-alone or is it intended for use over other glazes? I use Georgies Zinc Free Clear but intend to use larger quantities of clear in the future so I am looking for a recipe that I can make. Cheers, Amy

    Can this recipe be used to dip and/or pour the glaze? What about brush on? I am very new to the ceramics and value your feedback.

      Hi Jocelyn, Yes this glaze can be brushed or poured on or used for dipping. If you are brushing it on, we would recommend 2-3 coats and if you are dipping try a 2–4 second dip. We would also recommend testing the application process that you wish to use on a test tile first before applying the glaze to an entire piece. Try testing a couple different application processes and compare the results.
