The easy-to-recognize rock became one of the first targets of organized "mining." It is probably a safe bet that all natural Once these discoveries were made, obsidian quickly became the raw material of preference for producing almost any sharp object. Obsidian was used to make knives, arrowheads, spear points, scrapers, and many other weapons and tools. People then discovered how to skillfully break the obsidian to produce cutting tools in a variety of shapes. The first use of obsidian by people probably occurred when a sharp piece of obsidian was used as a cutting These sharp fragments may have prompted the first use of obsidian by people. The conchoidal fracture of obsidian causes it to break into pieces with curved surfaces. The best way to learn about rocks is to have specimens available for testing and examination.

The mostĬommon color combination is black and brown obsidian swirled together - that's called "mahogany obsidian" (see photo). Occasionally two colors of obsidian will be swirled together in a single specimen. The colors are thought to be caused mainly by trace elements or inclusions. However, it can also be brown, tan, or green. Rainbow Obsidian: A baroque cabochon of iridescent "rainbow obsidian."īlack is the most common color of obsidian.

The amount of positive feedback that I’ve gotten from this one CSS sheet just encourages me to continue sharing with this incredible community.Types of Obsidian: The specimens shown above are from Glass Butte rockhounding site in central Oregon. We have collaborated on making themes more accessible to non-English speakers (Y&Y update soon come!) and also getting custom icons supported in Obsidian themes (which was super time-consuming, yet totally worth it, as it been widely adopted by other amazing theme developers)! This theme has also helped in creating a friendship between me and my friend. I’ve also received lovely messages from non-English speaking users telling me that this is the theme they recommend to their friends (which is the sweetest thing ever)! Since then, I’ve been receiving messages from many users about how this theme has helped them fall in love with Obsidian, migrate their notes to Obsidian, and push them into accepting Obsidian as their note-taking daily driver. I then posted screenshots of this theme in the Obsidian Discord, and quickly received messages asking if I would release it publicly. From this, I was able to create something that the both of us loved to take notes in. I’ve been helping her build a PKM system in Obsidian for her studies, including building a theme that would fit both of our design aesthetics. I actually built it by the request of my younger sister, who just started high school last semester. Yin and Yang is a theme I created from scratch earlier this year. It also retains Minimal’s compact headers, which maximize use of screen space, especially on smaller devices.īe sure to give Things a try if you haven’t done so already. While Minimal’s monochromatic palette is ideal for writing prose, Things excels for to-do lists, project planning, and informational notes. Another sleek addition on mobile is the relocation of the edit/preview toggle to a button that floats just above the right-hand side of the keyboard for easy reach.īut the most noticeable difference is the use of well-chosen colors for the headings and emphases. Things thoughtfully ghosts back markdown characters like ** in edit mode so they don’t compete with the words they’re formatting (most themes and even some otherwise polished native apps like iA Writer actually make ** bold with the word), and restores the word count to the mobile app. And I have 3 current favorites: Sanctum, which has already been nominated, Minimal, which has already won, and Things.Īs the dev acknowledges, Things is based on Minimal (it even picked up my font preferences from the Minimal Theme Settings plugin) with some charming tweaks and refinements. I’m one of those people (prepare to roll your eyes) who likes to switch themes depending on what I’m doing. Screen Shot Things Theme 1920×1080 120 KB
