Wrapping up at Pilchuck and bouncing around Tacoma, Seattle for a day or two. Here is that 22mm borosilicate star I made. Brian Gillespie the Rhino torch maker got it at the auction party for scholarships an stuff.

I also made that eclipse and a purple an pink hand pulled phosphor coated color test.

The thick borosilicate is interesting... Makes me wanna get some of those oxygenated torches.

One of the instructors here, Brian Gillespie works at Rhino and 3D printed this surface mix gas oxygen torch from stainless steel.

It was fun getting to try it out. It heats nicely- the surface mix makes it much softer than a Carlisle. It basically won't liquify or burn the glass- but IS hot enough for bending, and is a pretty wide flame height (area).

The heavier wall borosilicate is interesting. Annoying that it may need to be annealed promptly, but it could be a bit more durable... And larger? I do love my soft glass (soda lime wall thickness about 1.75mm).

This is making me want to get the German surface mix ribbon burner. Expensive, but will probably last forever.

With #Russia now being associated with murderous state aggression I feel "Russian dolls" (Matryoshka dolls) are a faux pas in the modern interior.

On a trial basis for the next week (or until my, uhm, housemate says otherwise) this lovely #Borosilicate #laboratory #glassware will fulfill the decorative role of "fun nested bunch of things"

I made this completely ridiculous tiny Thing at the end of a #borosilicate session and it’s too cute to toss but too small to do anything with and I have no idea what to do with it 🙃
I suppose eventually it will just end up under the couch or something!

As the studio was closing down I was able to carry out plans to sneak these pieces into the big kiln and move the manifold over for a proper bakeout. Excited to get these #borosilicate #neon pieces filled. Some #experimental #workinprogress indeed. Studio is closed today #badair, but we should be filling tomorrow. Fingers crossed!

Some phosphor dust coated tube in tubes. I was going to be filling them all today- but I forgot how unannealed borosilicate glass has a tendency to just crack on it's own when left for prolonged periods. I got the heat in part- but it's the heat out that I am forgetting.
Time to patch up cracks and wait for the kiln and technician stars to align once more. Excited to see how these coatings look.

Some more photos of the giant mega tube pain in the butt. Its now also really annoying to move any carry and takes up a bunch of space. Gonna get it annealed in a giant kiln and then bombarded afterwards because the manifold does not have wheels. Goodbye nice shiny giant electrode and hello oxidation. I hope to be able to take it out of the kiln hot and then go easy on the bombarding. Fingers crossed it doesn't become more of a pain and break on the pump.

While noodling with putting tubes in tubes, today I ran into an issue- the inner tube flexed over the 4 feet and was hitting the bottom. So I added those little scientific nub things. I think there is a name for them- and I probably didn't use the proper tool. They sure worked though.
I might have messed things up when I touched the inner tube with one of them. Still definitely learning the tube in tube bends

@alifeeney Some photos of the borosilicate neon thing I made yesterday. 38mm, "lavender" and 83 inches long- its a proper thick, heavy pain in the butt. It is neat though. Its getting a krypton fill.
The gas oxy crossfire torch setup is plenty hot for me, but this thick tubing could use a bit more heat. Another torch or two and a foot pedal an aluminized jacket and gloves and I should be good!

Made a few tube in tubes today at Urbanglass. The outer tube heats the inner and then they both bend. Its tricky, and I am still practicing for sure. Borosilicate is a very different glass and the gas oxy carlisle torches are pretty different- but so nice and hot! I gotta try larger diameter inner and outer tubes next time.
Excited to dust coat some of these, and make a few more!

Yesterday, I found out that I can do this at Urbanglass for only $5 per hour. Yep- there is oxygen running through those torches and that is #borosilicate #glass. Available in super large sizes, those #pyrex tubes can be heated just like the neon crossfire with this setup- one quarter turn of the tube heats all sides.
Double the fire double the fun! Seen here are a 12mm tube and a 25mm tube bent just like with neon. So. Much. Heat!

Some photos with my visit with Katie. The bent up #doodle in the kiln along with drawings of that I hope it will become. Sure is nice having Katie's help and wisdom. I want to make a 5 foot doodle- more room for bends than my little 2 foot one here. Katies tape wrapped glass tube holder was brilliant and much more steady than the cardboard based approach I knew. With a few more steps this thing will be glowy and silver coated and maybe even heavy!

Yesterday I visited my friend Katie in Philadelphia. She teaches Scientific glass at Salem and has worked at some of the best science glass houses in Southern NJ (A place known for science glass). I sought her help in making this double walled mirror tube idea. More on that later. I like the bib and bob of the hose spinning on the lathe. I fabricated the glass hose split adaptor- Katie fabbed the rest until I bent it. #sculpture

I had such a blast taking a #scientific glass class with Sally Prasch at Urbanglass. I learned to make ring seals with condensors, and how to bend a tube within a tube- fun but tricky stuff! I made a maraca, trombone/clarinet instrument that I still need to put a bell on. It would be fun to make a bigger, bass maraca-Tromlinet. Yes, the tube in tube stuff does have some neat neon and plasma possibilities too.

This #bracelet was made with three of my #lampworked #borosilicate #glass #beads connected by #bronze Full Persian segments and closed with a Saki Silver bronze toggle clasp.

Unfortunately this one's no longer for sale because it's in the collection of my daughter-in-law, but I have other similar items!

A Fascinating Plot Twist as Researchers Recreate Classic “Primordial Soup” Experiment

Science is built on reproducibility; if someone else can replicate your results, chances are pretty good that you're looking at the truth. And there's no statute of limitations on reproducibility; even experiments from 70 years ago are fair game for a fresh look. A great example is this recent reboot of the 1952 Miller-Urey "primordial soup" experiment which ended up with some fascinating results.

At the heart of the Miller-Urey experiment was a classic chicken-and-the-egg paradox: complex organic molecules like amino acids and nucleic acids are the necessary building blocks of life, but how did they arise on Earth before there was life? To answer that, Stanley Miller, who in 1952 was a graduate student of Harold Urey, devised an experiment to see if complex molecules could be formed from simpler substances under conditions assumed to have been present early in the planet's life. Miller assembled a complicated glass apparatus, filled it with water vapor and gasses such as ammonia, hydrogen, and methane, and zapped it with an electric arc to simulate lightning. He found that a rich broth of amino acids accumulated in the reaction vessel; when analyzed, the sludge was found to contain five of the 20 amino acids.

The Miller-Urey experiment has been repeated over and over again with similar results, but a recent reboot took a different tack and looked at how the laboratory apparatus itself may have influenced the results. Joaquin Criado-Reyes and colleagues found that when run in a Teflon flask, the experiment produced far fewer organic compounds. Interestingly, adding chips of borosilicate glass to the Teflon reaction chamber restored the richness of the resulting broth, suggesting that the silicates in the glassware may have played a catalytic role in creating the organic soup. They also hypothesize that the highly alkaline reaction conditions could create microscopic pits in the walls of the glassware, which would serve as reaction centers to speed up the formation of organics.

This is a great example of a finding that seems to knock a hole in a theory but actually ends up supporting it. On the face of it, one could argue that Miller and Urey were wrong since they only produced organics thanks to contamination from their glassware. And it appears to be true that silicates are necessary for the abiotic generation of organic molecules. But if there was one thing that the early Earth was rich in, it was silicates, in the form of clay, silt, sand, rocks, and dust. So this experiment lends support to the abiotic origin of organic molecules on Earth, and perhaps on other rocky worlds as well.
