How Can I Get Something Treated by MACC?

  • Examination of Artwork and Objects – All items must first be examined by a MACC conservator. Make an appointment with MACC at (612) 870-3120 / to bring and leave your piece at MACC’s secure museum facility. There is a $100 cost for the in-lab examination for non-members. (On-site visits require scheduling conservator time.) During the examination, the conservator will detail the condition of your piece, perform tests and determine the proper conservation treatment. The conservator then provides you with a written Condition Report and Treatment Proposal.

  • Approving the Treatment – Sign and date the appropriate lines on your MACC Condition Report and Treatment Proposal and mail or fax back to: MACC 2400 Third Avenue South, Minneapolis, MN 55404, Fax 612-870-3118. Your treatment will then be put into the conservator’s queue (schedule).

  • Treatment Conservation – Treatment work begins when your piece is reached in the conservator’s queue. All treatments conducted at MACC adhere to The Code of Ethics and Guidelines for Practice of the American Institute for Conservation of Historic and Artistic Works.

  • Completion – When conservation treatment on your piece is complete, you will receive an invoice for MACC’s services. Once payment is received, you may pick up your piece from MACC’s facility or arrange for return shipment. You may also choose to pay for your treatment when you pick up your art or artifact. Make an appointment with MACC at (612) 870-3120 /
