All materials that remain in The Crucible after the class has ended become property of The Crucible.

Behavior Policy

The Crucible strives to create an environment in which respects its participants’ physical and emotional well-being. Students are expected to conduct themselves with respect for the individuals, the organization, and the facility at all times. Students will review Studio Rules and Group Agreements of The Crucible during their first class. The director reserves the right to enforce these rules, and anyone in violation will be subject to consequences including, but not limited to, immediate dismissal from classes without refund


Each class fee includes a non-refundable registration fee of $50. If needed, you may withdraw from a class for any reason up to seven days prior to the start of the class. You will receive a refund minus the $50 registration fee. There is no refund if you withdraw from a class less than seven days before the first class meeting.

To withdraw from a class call (510) 444-0919, Mon- Thurs., 10 am to 6 pm, or Friday, 10 am to 2 pm, and you will receive a confirmation code for your withdrawal.

The Crucible reserves the right to cancel any class with insufficient enrollment at any time. If we cancel a class, you will receive a full refund, or you may choose to transfer to another class if space is available, or hold a credit on account for future use.

There is a $35 charge for returned checks.
