vapor..kiln shed ?

updated thu 22 apr 99


joe & lisa cecere on wed 21 apr 99

Clayart People...I am currently building a new studio...1/2way completed.
Because it is attached to my home (for water and..I live in NJ...building
variences galore if I had it separate) anyway...we did get a permit to
build a shed for my kilns...4 feet from the door. Does anyone have
information on what I might need for this....I'm assuming I can just pop one
up....with a small vent for heat and windows for cross venting. Any smart
hints can be sent to my e-mail Thanks
