I am going to be re-glazing some pieces and refiring them. I need a thicker application of glaze to get the color I want. I normally glaze fire on medium speed in electric to Cone 5, which takes about 8.5 hours. Can I refire to Cone 5 at fast speed this time, or should I stick with medium? Thanks!!
Tip of the Day. A while back, I had fired some cups to ^6. Sadly, I didn't do a, Viscosity, Hydrometer or Specific Gravity test, and the cups didn't have the glaze finish I'd hoped for. So I looked for answers and found a few, but they didn't work for me. So I came up with this idea. One of the suggestions was to heat up the cup and the glaze it, but I couldn't wrap my head around how to do it, sooooo, enter the Microwave. Albeit, it only works for items you can fit in the microwave, but that's probably were the most mishaps happen. Here's how: 1. Prepare table, drying area with newspaper for cups to dry. 2. Tape the foot ring or any part you don't want glaze on with painters tape, blue or green works, I used both. 3. Do a viscosity test. 4. Microwave you piece. I did 4 cups at a time, for one minute. I used a 700 watt microwave. Do a test for how long. You should be able to handle it without burning your skin off. 5. Dip in glaze using dipping tongs. I soaked for a 5 sec. count. and set on paper covered table and let dry overnight or till they can be handle carefully without scraping of any glaze. I didn't have any glaze rub off. 6. carefully pull tape off. I didn't do this, but I could have waxed the band over to avoid the running. 7. Re-fire to ^6. Before and After Note: I'm sorry I didn't just photograph all the steps. Next time for sure. Hope this helps.
Hi, Thank you for allowing me to join this forum. I have a background of fusing glass so, other than in school, I am pretty dumb when it comes to ceramics. I want to make a clock out of a Bopla plate. I know I could get stick on letters, (or some sort of permanent paint?) for the clock face. I think it would look much more professional if I could re-fire it with the clock face numbers. I have used fired on decals on fused glass before. Is it possible to re-fire commercial porcelain without any loss to the design. The decals I have fired onto glass fire at around 1000 degrees. I don't know temps for ceramic decals though. This is for a Christmas present. Thanks, Dave Kingman P.S. If this is possible, I would appreciate finding a source for ceramic decal numbers 1-12. The place I used before required an image file and was pretty expensive.
