ruthe314 Posted January 27, 2012 Report Share Posted January 27, 2012 Hi, I bisqued my pots to 04, then glazed and fired them to 05. Many of them came out with pinholes. I've been reading about reglazing. Does anyone have info about doing this? Do I refire to 05 again? Or hotter? Should I soak when I reach the proper cone? If so, How long should I soak? I also have many pots that have not been glazed yet. Should I rebisque them before I glaze. I did have a problem with the power going off during firing in the initial bisque. Thanks for helping a newbie! Ruthe Link to comment Share on other sites More sharing options...
Marcia Selsor Posted January 27, 2012 Report Share Posted January 27, 2012 I have filled pinholes in a ^6 glaze by stuffing the dried glaze into the pinholes and refire in a normal glaze firing. Can't see why there would be much difference in doing the same thing for 05. Marcia Link to comment Share on other sites More sharing options...
scoobydoozie Posted January 27, 2012 Report Share Posted January 27, 2012 The use of witness cones on the shelf during firing would have alerted you to an underfire (or overfire) of the kiln load so you could have refired before glazing if necessary.

Thanks for helping a newbie! Ruthe It seems to me that you have a problem with the pinholes are from where gas has escaped and the glaze has not healed over. A soak time at the top of the glaze firing should handle that situation. I don't think it needs a rebisque, just a soak time. If you find you need to reglaze, try warming up the pots first to help the glaze adhere to the pot. Link to comment Share on other sites More sharing options...
bciskepottery Posted January 27, 2012 Report Share Posted January 27, 2012 You might want to include a 15 minute hold for glaze loads to give the glaze more time to melt. That is standard for my glaze loads at ^6. Link to comment Share on other sites More sharing options...
SunsetBay Posted February 2, 2012 Report Share Posted February 2, 2012 You might want to include a 15 minute hold for glaze loads to give the glaze more time to melt. That is standard for my glaze loads at ^6. I have a related question as I just tried a different firing schedule and ended up with a bunch of pinholing and some tiny isolated bits of what look like heavy crawling. My usual ^6 schedule has been 3 hours on low, 3 hours on medium, close lid and turn to high. Let kiln-sitter shut off kiln. I just tried this: 2 hours on low, 2 hours on medium, close lid and turn to high; add 1 hour soak on low after kiln-sitter shut things off. Any idea why this different schedule would cause these issues? Also, I'm assuming I can refire (using my usual schedule, I think!) and hopefully heal all this over. Any suggestions about that?
