I have a small studio. I had almost enough bisque to do 2 glaze loads in a row. To fill the 2nd glaze load I need a few more pieces. Any negatives to throw them and glaze the green ware and mix in with my standard load? I know some potters do one firing and no bisque. The only negative that I am aware of is that the pieces will be very fragile. I think I can be very careful for 3-4 pieces. Any other considerations. Thanks for any info.
