Dipping glazes allow for quick and efficient glazing on large \npieces or a large number of pieces. The amount of glaze deposited on \nbisque is primarily a function of glaze viscosity and the amount of time\n the bisque is left in the glaze – careful attention to these two \ndetails are critical to obtaining satisfactory results.\u003c\/p\u003e\n\u003cp\u003eMayco’s clear dipping glazes are certified non-toxic and food safe.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: bold;\"\u003eProduct Features, Attributes, and Application Recommendation\u003c\/span\u003e\u003c\/p\u003e\n\u003ch4 style=\"visibility: visible;\"\u003eApplication Recommendations:\n\u003col\u003e\n\u003cli\u003eContainer should be kept tightly closed when not in use.

Non toxic \nglazes will not move or run as much as leaded glazes; our internal \ntesting of major brands of color and clear glazes on Chinese, Italian \nand US domestic bisque show that higher temperatures and fewer layers of\n glaze (color and clear) produce better fired results. You may want to \ntest our findings to see if they help you achieve better fired results.\u003c\/p\u003e\n\u003cp\u003eRe-firing the piece may be possible to help clear up the finish. \nAlways use pyrometric cones, such as Orton’s self supporting witness \ncones, to make sure your kiln is firing to the proper temperature. Place\n cones on the top, middle and bottom shelves to test for even \ntemperatures in your kiln. If you normally use cones on the middle shelf\n only you should do the three shelf test periodically to make sure you \nare getting even heating in the kiln.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: bold;\"\u003eQ:\u003c\/span\u003e I find dipping tongs difficult to control and use\n – especially for large pieces.
