Hi, I noticed that sometimes after applying glaze, about 24 hours later, it sort of pulls away from the bisqueware.
Photos here: https://www.facebook.com/groups/maycomudroomsociety/permalink/1966264987085497/
I'm curious if it will still adhere to my piece in the cone 6 glaze firing that I plan to do soon? Or should I wash it all off and start over?
For context, these pieces are Laguna B mix (no grog), bisqued to cone 04 in a friend's electric kiln. I glazed the outside of each bowl by dipping 1 time, then brushed 2 coats of Mayco dark flux into the bottom of each bowl and then, after that was dry, poured Mayco dry glaze into the bowl and poured it out.
Thanks in advance for any help. Rachael

Hi min and Bill, thank you for your responses.
I couldn't see how to add photos when I originally made the post but now I get it so I added one above.
Sorry for my garbled communication.
I am using Mayco brand dry dipping glaze, which is a powder that you mix with water in a bucket and the application is done either by dipping into the bucket or by pouring it into and then out of your form.
I also use Mayco Flux, which you brush on.
So my process with these pieces was:
1. Bisque to cone 04
2. Brush 2 coats of Mayco flux onto the inside bottom of each bowl.
3. Dip the piece into glaze for coverage of outside of the form.
4. Pour glaze into the inside of the form and pour out.
Between each step I allow the glaze to dry completely.
I noticed the cracking occurred after 24 hours.
It's been very humid lately and I don't use any air conditioning.
Hope this information helps! Thanks a bunch.
