Studio Plus Glaze - Caribbean

A note on color accuracy:

While we take great care to ensure our digital swatches represent colors as accurately as possible, physical application creates its own unique nuances. Digital monitors display colors differently depending on your settings, and factors like application thickness and ceramic firing temperatures can uniquely impact your final results. Think of these images as your trusted guide, but we always encourage our users to do test tiles prior to using any finished pieces.

What firing process can I use to get the best results with Speedball Studio Plus Glazes?

To get the best results with Studio Plus Glazes, we recommend bisque firing to cone 05/04. The (6) mottling colors within this line are designed for use at low-fire temperatures (Cones 06/05) only. The remaining (18) core colors in the line are for use for a much broader firing range (Cone 06-6). We HIGHLY recommend making test tiles to verify fit and performance with your preferred clay bodies, application, and firing schedule.

Can I adjust the thickness of Speedball Studio Plus Glazes?

Yes! Distilled water is recommended to thin them down as applicable, or let them sit open to have moisture evaporate from them, to help thicken them if needed.

Can Speedball Studio Plus Glazes be mixed to make new colors?

Yes! They can be mixed to form other colors before firing, or they can be layered in firing if desired.

Can Speedball Studio Plus Glazes be used with your Underglazes and Mid-Fire Glazes?

Yes! We recommend doing test tiles and your own dinnerware safety testing prior to use on any finished pieces.

What is the shelf life of Speedball glazes and underglazes?

Speedball glazes and underglazes have a shelf life of 2 years after manufacture, however when properly stored and maintained they can last much longer.
