Obsidian is an extremely hard, volcanic rock which makes it difficult for most people to work with. Luckily, there are some ways that you can make the process easier! We’ll discuss the different types of obsidian and their attributes, as well as how to cut them into smaller pieces or shape them into carvings without breaking them. Let’s get started!
Different types
Obsidian is a type of volcanic glass that is formed when hot lava cools quickly. The speed at which it cools determines the quality and color of the obsidian. There are several types of obsidian, each with its unique properties:
- Black Obsidian. This variety is the most common and usually has a shiny, glassy surface.
- Snowflake Obsidian. This variety is made up of white or gray crystals that are arranged in intricate patterns. It’s also known as “gem silica.”
- Rainbow Obsidian. Most commonly found throughout the state of Oregon, it has black and brown bands with colorful ripples throughout.
- Mahogany Obsidian. This variety is a deep red or brown color and has a glossy sheen.
- Pearly Obsidian. This type of obsidian is translucent and often has a pearly or iridescent finish.
The different types of obsidian can be distinguished by their appearance, but they all have the same basic properties. Obsidian is a hard, brittle rock that fractures easily. It’s also very sharp, so it can be dangerous to work with if you’re not careful!
Tools needed for cutting obsidian stone
There are a few basic tools that you’ll need to cut obsidian:
- A chisel. This is a sharp, beveled tool that is used for striking or cutting. You can use it to break off small pieces of obsidian or carve out shapes.
- A hammer. This is a blunt tool that is used to break off chunks of obsidian.
- A vice grip or clamp. This is used for holding the stone in place while you work on it so that your hands are free to use the tools above.
- Safety glasses and gloves. Obsidian may be hard, but shards can still fly everywhere if struck incorrectly! It’s important to protect your eyes and hands while you’re working.
Hint: you can also cut obsidian with a rock cutting saw. However, it’s important to use the right type of saw blade because obsidian is a very hard material. A diamond-tipped blade is best for this purpose.
Step by step instructions on how to cut obsidian stone
Now that you have the necessary tools, let’s learn how to cut obsidian!
First, select the piece of obsidian that you want to work with. It’s important to choose a piece that is smooth and free of fractures. If there are any cracks or chips in the obsidian, it will be difficult to work with and may break during the cutting process.
Next, place the obsidian in a vice grip or clamp so that it is secure. If you’re using a hammer, hold the chisel against the edge of the obsidian and strike it with the hammer to break off small pieces. Be careful not to move the chisel too quickly or you might break it! You can also use a series of small strikes to remove more material without breaking your tools. If you’re using a saw, rest the cutting edge on top of where you want to cut and draw it back towards yourself so that it barely scratches the obsidian. Repeat this process until there is a deep enough groove to saw through.
Once you have made the cut, use the chisel to break off the remaining piece of obsidian. If it’s not already in small pieces, use the hammer to break it into smaller bits that are easier to work with. You can now begin carving out your desired shape!
Be careful when working with obsidian. It is a very sharp rock and can easily cause injuries if you’re not careful. Always wear safety glasses and gloves to protect yourself from flying shards.
Tips and tricks
- If you’re having trouble breaking off chunks of obsidian, try heating it up with a torch. The heat will help to soften the rock and make it easier to break apart.
- When sawing through obsidian, use a very slow and steady motion. Don’t try to force the saw through the stone or you might break it.
- Remember that the different types of obsidian have similar properties. They are all very sharp, so take care when working with them!
- If you’re using a hammer to break the stone apart, place some newspapers or other material on the ground before beginning your work. This will help to protect both yourself and your workspace from flying shards.
- If you’re not happy with the results of your first try, don’t worry! Just keep practicing and you’ll get better with each attempt.
