Tap-hole clay is typically injected into the tap-hole of a pyrometallurgical furnace at the end of a tap in order to stop the flow of liquid process materials. The purpose of the clay is to create a seal between the liquid process materials inside the furnace and atmosphere. The clay needs to deform quickly under pressure to create a tight seal and therefore the rheological properties of the tap-hole clay play an important role. To ensure that their materials remain workable, commercial suppliers of tap-hole clays limit the shelf-life of their materials to between 6 and 24 weeks. Datasets , generated by pilot-scale clay-gun operations, are presented here for three different tap-hole clays for which the shelf-life was extended beyond the recommended shelf-life. The clays were stored in a controlled atmosphere for which the atmospheric conditions were logged. In all three instances, the data collection process was automated with raw and/or filtered data, available as Excel spreadsheets, published in an online repository. For the purpose of this paper, the data was analysed and presented as graphs or in tables. The data will be of future use for further studies into the effect of tap-hole clay rheology on clay-gun performance.
