I have been reading the decal on the pottery. Keith Phillips and Cynthia Guajardo describes their process at his and her blog. That makes me very curious. I bought the HP 1020 laser printer and the laser printer decal paper off the ebay last week. I made the decal of the Hungerford Urban Artisan logo on the glaze fired cups, and put in the bisque kiln to cone 06.
Most recommended to cone 04, though I like the bisque pieces to cone 06 for better fit of the glaze. The toner of the laser printer contains 50% iron, that is fused to the glaze, and become very nice sepia color. I like how the test turned out, especially with the rutile blue and the amber glaze combination.
Today, I was glazing and loading the kiln for firing tomorrow. I wanted several cups made with logo before the studio opening this weekend, but don’t have enough time to glaze fire, attach the decal and bisque fire them. So, I glazed the cup, waxed over it, and attached the decal on the waxed surfcae. I have no idea this would work or not.
I think making a design for the decal to fit with the glaze would be the most difficult part, and have a whole winter to think about.
Glazing today.
My studio gets very dry, and the glaze bucket does loose its water content in a span of two weeks even with the lid on. I draw a line on the interior wall of the bucket when finish glazing so I knew when it lost water.
When I glaze, I usually check the thickness of the glaze by using the hydrometer or weighting the glaze (10 cc). And I still had inconsistent results of the glazed ware. I suspected the Epsom salt being the cause. I use the Epsom salt as the flocculant, which slows the settling of the glaze.
Last time, I mixed the new batch of glaze; I did not add the Epsom salt and tested the new batch of glaze in the last firing. (Test, test test! I do measure carefully, but I still mess up time to time. ) Now I can mix with old batch of the glaze safely. I checked the thickness by weighing 250 cc of the glaze this time; first the glaze without the Epsom salt, then added the Epsom salt in the glaze. Both weights came up 275 g. The result showed the Epsom salt does not interfere with the weight of the glaze. I guess 10 cc was too small of sample. I did not test today, but I was very sure the hydrometer was inaccurate with the glaze containing the Epsom salt.
We had another snow overnight. This is the perfect timing! (I wish the warm weather is here, though.)
The design of the turquoise rice bowl is somewhat different from the most of my bowls. I had an image of the spring garden in snow or remaining snow at a high mountain in the early summer. I probably started glazing this way in winter, wishing then spring. Cook rice is hot to serve, not cold; there is some fault to my idea. Ha, ha… One of design came out with what I intended.
