Magnets are super incredible! I took a module on magnetism in university and they are indeed magic in three different forms! What we call “magnets” are ultimately just ferromagnetic materials with all their magnetic domains aligned to create a net magnetisation, but we use the best ferromagnetic material (Neodymium) to do it. Also, every material in existence experiences a magnetic response, but depending on the election mobility will either temporarily align with a magnetic field (paramagnetism) or oppose it (diamagnetism) the difference is that they lose their magnetisation when the applied field is switched off, but ferromagnets undergo “hysteresis” whereby the alignment is (effectively) permanent

Brent, you are a fantastic human being, a great hobbyist and also an amazing chemistry teacher! Thank you for this video!

so i generally love your videos, and i feel your one of a hand full of artists for minis not selling something.

Great video, Brent. I will pay more attention to how accurately I mix my epoxies. I sometimes don't get a hard result like I like to see. I will weigh my halves now to make a better bond.

As a high school chemistry teacher who loves to nerd out about organic chemistry, as well as having an interest in miniatures, I loved this video. Mostly very easy to understand, even for someone without a chemistry degree. I love your videos. The only part that I felt was I little inaccessible was the explanation at 11:40 or so. Probably could have used a bit simpler language. I love that you are getting this fascinating stuff out to an audience that wouldn't normally look into it, and so I only say that because I want to see more content, and would love to see it stay really accessible to people without a chemistry degree.

Yes, this is the part I got a little lost. I am absolutely not a chemist, and I'm still trying to work out the definitive difference between a covalent and an ionic bond, as technically they both utilise electrons.

I learned more about chemistry than in all my school years.

So satisfying to listen to the language of chemistry and as ever, root for the lone pairs. The whole discussion regarding bases with multiple bonding sites at either end, yet still avoiding the terms polymer, or polymerisation was oddly compelling. Kept waiting for it like an expected character bursting into a story. A tip, milliput is a pretty inferior sculpting putty, but once kneaded can be softened to a buttery paste with isopropyl alcohol (propan-2-ol whilst we're speaking chemistry!) and a good bit of stirring. I'll go all the way down to a brush on surface texturing liquid that'll do rust, dust and corrosion, but also a couple of touches with a fingerprint and it turns flat shiny plastic into coarse cloth weave. Revolutionises lazy sculps and ages/weathers metals for custom stuff. It totally outshines that as a butter though (millibutter) it's awesome for gap filling - you'll just never go back to anything else. (Huge thanks to Marco at NotJustMecha for these utter game changers - guy's another genius) Paste it in, fit and then smooth with a wet paper towel, add more for really ill fits and your conversions, even build it up on an armature. The butter will last days in a screw topped (spice) jar with just a bit of extra alcohol in there.

I have used two part epoxies in my woodworking for a few years now. Good stuff but can be tricky to get just right. Bubbles mostly :( Thanks for the in depth explanation. However my main pleasure in this video was your ginger assistant. Pleasant memories came to mind of my past cat who would sleep in a cardboard box in my workshop. A good friend was she.

Woohoo! Epoxy science! Guess I am up for another half hour.

I wish Brent would have been my High School Chem professor.

For the percentage mixtures, you ought to wait longer and test again after a few days. Some of them just harden at different rates with the ratio off.

Very clear, great tone. Not dumbed down, and not too technical.

Traditional sculptors often use mixes of various epoxy putties to get different characteristics. Kneadatite A+B (greenstuff) has a consistency like stale bubblegum through much of its working time and a very long working time. Apoxie Sculpt (or Magic Sculp, which seems virtually indistinguishable) has a softer working consistency, faster cure time, and a harder (and easier to sand or file) final result. A mix of the two seems to be pretty popular for miniatures sculpting. Thanks for the information. This was really entertaining and I'm sure I'll find a way to use it in the future.
