Students taking classes have open studio time but are limited to 20 pieces (under 3 lbs) per month that is included in the class cost for beginner or intermediate. Our small community studio limits firing space to a half-shelf per person/per firing maximum. It can vary because some people don't produce more than a couple of items per firing...but it lets people know what their space limit is. If someone wants to produce a large quantity/piece they can pay for a full kiln load.
