Laser engraving is a popular technique for creating custom designs and patterns on a variety of materials. Baking soda can be used as a masking agent in laser engraving to protect certain areas of the material from the laser’s beam. This allows for the creation of intricate designs with precise details.
To use baking soda as a masking agent, simply mix it with water to form a paste. Apply the paste to the areas of the material that you want to protect from the laser. Once the paste is dry, you can then engrave the material as usual. The baking soda paste will vaporize when it is hit by the laser, protecting the underlying material.
