Obsidian is a naturally occurring volcanic glass that is formed when molten lava cools rapidly without crystal growth. It is known for its unique physical properties, such as its glossy and smooth texture, and its distinct dark color, which can range from black to various shades of brown and gray. Obsidian is primarily composed of silica and is characterized by its sharp edges and high density.

Due to its natural hardness and brittleness, obsidian has been used for centuries by ancient civilizations for various purposes, including tools, weapons, jewelry, and decorative objects. Today, it continues to be valued for its aesthetic appeal and its usefulness in crafting sharp cutting edges. Obsidian’s ability to produce razor-sharp blades makes it a sought-after material for making surgical scalpels, arrowheads, and other cutting implements.

Overall, obsidian is a fascinating natural material with unique properties that make it ideal for cutting and shaping. Its beauty and practicality have made it a popular choice for artisans, archaeologists, and enthusiasts who appreciate its historical significance and its versatile applications.

Obsidian is a tricky material to work with. You have to be careful when cutting, and you should start as soon as your blade reaches its fastest speed so that the saw doesn’t damage either yourself or what’s being cut for any errors in judgment on behalf of Obsidians’ tendencies toward brittle nature which can cause breaks more easily than other stones do because they’re often slightly thicker slices but not always.

To polish obsidian, you will need some basic supplies including water, fine-grit sandpaper (around 400 to 600 grit), a polishing compound or powder, a polishing cloth or wheel, and a protective mask and eyewear.

Step 2. Prepare the Surface

Start by cleaning the surface of the obsidian with water and a mild soap to remove any dirt or debris. Rinse it thoroughly and ensure it is completely dry before proceeding.

Step 3. Sanding

Begin the polishing process by using the fine-grit sandpaper. Wet the sandpaper with water and gently sand the obsidian in a circular or back-and-forth motion. Keep the surface wet to prevent heat buildup. Continue sanding until the desired smoothness and shape are achieved.

Step 4. Polishing Compound

Apply a small amount of polishing compound or powder to a soft cloth or wheel. Gently rub the surface of the obsidian in a circular motion. This step helps to remove any remaining scratches and brings out the natural luster of the stone. You can use specialized polishing compounds designed for obsidian or general-purpose polishing compounds suitable for gemstones.

Step 5. Finishing Touches

After applying the polishing compound, rinse the obsidian with water to remove any residue. Dry it thoroughly and inspect the surface. If desired, you can repeat the polishing process with a finer grit sandpaper or a different polishing compound to achieve an even higher level of shine and smoothness.
