Macroscopic Characteristics of Minerals Part 2: Cleavage and Hardness

After examining color and luster, let's look at two more characteristics of minerals, cleavage and hardness. How do minerals break apart? How well do they scratch certain surfaces? Let's get a closer look!

I've always found a direct correlation between cleavage and hardness.

As a bachelor’s degree holder in Earth and Planetary Sciences, I would (thus far) recommend this series for anyone about to or currently taking 1st semester mineralogy. Good stuff and succinct!

[@mjjoe76]

The title made me briefly think this was Mineralogy After Dark. But interesting information! I don’t know much about the topic, but it’s neat to learn.

[@jomes4137]

I looked up cleavage on KZbin and ended up here wtf

[@rgbatom5145]

The struggle

[@radlerdramatizations]

I honestly always enjoyed learning and school for the most part but nobody has got me this excited to learn as you do!! Thank you as always for another great video!!

[@user-on7xs7it4o]

Appreciate your audience! For supporting I'll share with you some beneficial insight. Lets converse with the number above❤️

[@glennpearson9348]

I suppose after this video in the series we can now say Professor Dave has just begun to ... ahem ... scratch the surface on mineral knowledge.

[@waelfadlallah8939]

This became one of my most favorite series

[@darkwilly90]

the study of the principles of chemistry behind crystals and their use in describing structure-property relations in solids. Got it learn something new today

[@smallcutepuppy]

The ad I got before this video was for a woo crystal seller. 😂

I can't help but think of Land of the Lustrous when I see this series

[@nileshgupta3961]

hello dave, i'm sorry to comment out of context of the video but can you make a video about the documentary "what the health" on netflix? it states some very strange stuff that are supposedly backed by scientific studies like, " eating 1 egg is as bad for you as smoking five cigarettes", which makes me freak out everytime I am eating an egg. Googling doesn't help either as there are confusing results. i think it would make a great video because you have a lot of interest in debunking pseudoscience. If you don't want to target that documentary in particular, just tell me is an egg is really as bad as 5 cigarettes so that I can stop freaking out and make an informed decision.

Plz do more videos on physics

[@sciencenerd7639]

beautiful

[@Killbayne]

you can examine the cleavage, but you gotta ask it first.

[@Thisismyhandle329]

Why can't you be my professor

[@donchristie420]

Why can’t you be my neighbor

[@waelfadlallah8939]

[@Crasson08]

You said hard. Heheh

[@Haligonian]

When more debunks? 😥

[@swoyaman4969]

Hey professor Dave , just here to remind you to debunk sadhguru

[@nileshgupta3961]

watch science is dope's debunk I think it's pretty informative.
