The reasons for venting the kiln are many: 1. Noxious gasses - firing silica
bearing materials & glazes produce all kinds of nasties; 2. Taking away
heat - if you fire just to bisque temps you are up around 1900 F! 3. Time &
quality of firing - venting improves glaze surfaces, produces more even heat
& shortens firing time. Having said that, you ought to think about it -
clay is a wonderful medium for kids. It is relatively cheap, extremely
flexible and produces permanent forms. You can do this without a
conventional kiln, but it sure is easier! Venting does not have to be a big
deal - if it is in a separate room, a simple vent fan will do the job. Hope
this helps ( and there I go, proselytizing about clay again - I can't help
it, Lisa!) Dennis
