With the slag cake now cool enough, we took it out of the furnace and started documenting its weight and taking samples. Finally, after a quick photoshoot of the cake it was finally time to crush it and prepare it for further steps of the experiment next week.
Since further experiments were planned for tomorrow but also rain was forecasted, we decided to dig another pit beneath a shelter so we wouldn’t be affected by the weather. After lining the freshly dug pit with clay and after 4 days of work finishing the grinding of the matte, we had the opportunity to do what every four-year-old would envy us for. With the freshly ground matte and waterbuffalo manure as fuel we formed small pellets which were roasted overnight to get rid of the remaining sulfur.
