The Charcoal Foundry has a capacity of 100 with a fixed burning time of 8 hours and 20 minutes (30,000 seconds) if completely filled. 100 regular logs give 100 charcoal, 100 Oak Logs give 200 charcoal, 100 Willow Logs give 300 charcoal and so on.
1 log does amount to approximately 300 seconds. The type of log does not matter for this timeframe.
