CLOUDY BOTTLES........HELP PLEASE!!!!!

[lanie]

Hello, Can anyone help me please.....I put decals on bottles and melt them in my kiln, when finished they are used for food, some of them are coming out cloudy......can anyone tell me how to stop this from happening? I have heard of SPRAY A and BORAX.....would either of these help, if so would they damage the decals, would they still be food safe, and how would I use either of them??? I would appreciate any help or suggestions........Thanks in advance!!!! Lanie
