After placing an artifact of any type, you may decide that you do not want it in this exhibition room or in this exhibition at all. It must be mentioned here, that every artifact can be placed in as many exhibitions as you want but only in one room per exhibition. You can easily remove an artifact from an exhibition room. In the ‘Curate exhibition room’ overlay, left click on a specific artifact and select the second option that appears to you, which is ‘Remove’. Selecting Remove, you remove this specific artifact from this exhibition room and you may place it in another room in the same exhibition or not use it at all in this exhibition.
