Ian Saginor @volcanoclast.bsky.social · 21/09/2026I wish I had taken a picture with cross polarized light. You’d see those micas light up. 010
Ian Saginor @volcanoclast.bsky.social · 20/09/2026This is plane polarized light, so it’s hard to see, but can you find the micas hiding in there? 000

Ian Saginor @volcanoclast.bsky.social · 22/05/2026Bake at 425 for 12 minutes. Lower temp to 325 for another 10 minutes. This is the timing I use, but you should adjust to your preference and to your oven. 030
Ian Saginor @volcanoclast.bsky.social · 22/05/2026When oven is ready, place pan with butter into oven. Set timer for 3 minutes. Dump all ingredients into blender and blend it well. This whole operation can be done while butter is melting. When butter is melted, put out pan and gently pour evenly into all 6 cups. Should be about 3/4 fill. 130
Ian Saginor @volcanoclast.bsky.social · 22/05/2026Popovers Pre-heat oven to 425. Place generous pad of salted butter into each popover cup. Pre-measure ingredients: 1 1/4 cup flour 1 1/4 cup milk 3 eggs 140
Ian Saginor @volcanoclast.bsky.social · 22/05/2026If the problem is that they stick to the bottom, any basic new pan will help. Otherwise, the recipe and procedures for getting these every time is pretty simple. 130
Ian Saginor @volcanoclast.bsky.social · 14/04/2026Some (most?) states waive the testing requirement with a certain number of years of work experience. Worth checking. 120

Ian Saginor @volcanoclast.bsky.social · 04/10/2025Opalite (for all you new fans of geology) is glass that has been made to resemble the opalescence or “play of color” found in natural opal. Sometimes, natural colorless opal is referred to as opalite. Either way, enjoy, but please do not pay a lot of money for it! 010
Ian Saginor @volcanoclast.bsky.social · 04/10/2025I like the updates they made to the original design. 010
Ian Saginor @volcanoclast.bsky.social · 13/09/2025Looks like bivalve shells to me. The thin white curved ones are on edge, the others are parallel to the surface. They just look different depending on their orientation. 100

Ian Saginor @volcanoclast.bsky.social · 02/08/2025Congratulations to @volcanologist.bsky.social on the new book! What an absolutely stunning cover. 020
Ian Saginor @volcanoclast.bsky.social · 26/03/2025Garnet amphibolite, Gore Mountain, NY. My first ever field trip and the moment I decided to be a geologist. 060
Ian Saginor @volcanoclast.bsky.social · 07/03/2025Isla de Ometepe made up of volcanoes Concepcion and Maderas sitting in Lake Nicaragua. Eruptions, earthquakes, sharks. 000
Ian Saginor @volcanoclast.bsky.social · 27/02/2025Museums may have larger pyrite specimens composed of many crystals, but this is the largest single crystal of pyrite I have ever seen. I bought it years ago and never seen anything else like it. 000
Ian Saginor @volcanoclast.bsky.social · 26/02/2025Have all the geologists arrived at Bluesky yet? Let’s find out. Icelandic coast from helicopter. 050
Ian Saginor @volcanoclast.bsky.social · 23/02/2025Wow. What a great question. I’m going to say no. Volcanic material rises due to 1) Explosive force or 2) Convection in a rising column of ash and gas. No explosion is powerful enough to breach the upper atmosphere. Eruptive columns get closer, but eventually cool down enough to stop rising. 030
Ian Saginor @volcanoclast.bsky.social · 18/11/2024The Lego mineral set has been approved! No word yet on when it might be available. Congrats to the designer. 010
Ian Saginor @volcanoclast.bsky.social · 17/09/2024This is one of the thin section pictures. It had some garnets. 020
Ian Saginor @volcanoclast.bsky.social · 17/09/2024Who knows if it’s the same rock, but it sure does look like it. 120
Ian Saginor @volcanoclast.bsky.social · 17/09/2024My first thought was “I wonder if it’s from New Hampshire?”, because I collected a rock like that maybe 35 years ago. Years later, someone found another and asked what it was, so I made thin sections and had chemistry done. It was an amphibolite with a likely basaltic andesite protolith. 110
