Abstract Improvements were made to the experiment of extracting crude potassium carbonate from plant ash. A micro charcoal furnace was designed to replace alcohol lamps, a micro stirrer was designed, and an integrated leaching and filtration device was designed, greatly reducing the experimental time and making the experiment easier to promote. This paper purposefully explored new uses of various commercial products and applied them in chemical experiments, making experimental equipment low-cost, easy to transport, energy-saving, green, and universally applicable.
