In the field of materials analysis, chemical and color etching continues to play a crucial role in sample preparation and structure revelation, yet its approach is often more empirical. While classical metallographic methods dominate, insufficient understanding of the process creates room for innovation. To improve this situation, the development of new techniques allowing for structure observation during sample preparation is essential to minimize the role of chance. While the first professional equipment was recently introduced, this contribution aims to verify in situ monitoring of structure during chemical etching using common laboratory equipment and a stereomicroscope with a camera and tablet. The method may encounter limitations due to the magnification and resolution capabilities of the stereomicroscope. Manipulation with a pipette and the risk of lens contamination with etchant can also be challenging. Additionally, etching in deeply dark etchants and ensuring adequate stirring of the etchant can be difficult. Nevertheless, this method offers new possibilities and can be beneficial for certain applications. To achieve a more comprehensive understanding, experiments with various materials and etchants are important to better grasp the limitations and possibilities of this innovative technique. Automation of the method and process control using machine vision could be a future challenge.
