Make Glow in Dark Powder from Crushed Oyster Shells 

I remember this from a kid's chemistry book in the 50s - yes, I'm an old geek! The missing ingredient is an activator of bismuth, something around 10 to 50 ppm of bismuth subnitrate. Those were the days that a friendly chemist would help out a geeky schoolkid - now you'd both be targeted as terrorists. Why use a crappy test-tube? Should be using a crucible for high temp chemistry fusing. A couple of antacid tablets containing Bismuth subsalicylate crushed up with half a dozen oyster shells would give an approximate amount of activator. Pretty disappointing as a luminous chemical as it is hygroscopic and after sucking in enough moisture quickly looses it's luminous ability.

Will it work if I were to use a metal container for heating it, but still got it just at hot?

Do you think it will work with clam shells ?

I'm trying to make a scintillator for detecting alpha radiation. Can zinc sulfide be used? Is there a compound that is better at detecting alpha radiation than zinc sulfide? Thank you for your time.

@myst32YT I wonder if it's magnesium or sodium. NaCl and MgSO4 are the two main components of sea water.

Could i use a steal container instead of a glass tube? And then, what is the chemical in the oyster shell witch does the job?

is it safe to do it at home

What sulfur and oyster ?

Will this or the zinc sulfide powder glow only once? If I left either powder be in a dark place, and then took it out a couple of weeks later and tried the test again, would it not glow anymore? And, if it does last longer than a day, can it be added to paint (if so, is oil based better than water or acrylic based)? Also, what is the finished compound called, and is it the chalk in the shells that makes it work? Thank you for both the zinc sulfide video and this one, I'm trying to figure out if body paint could be made at home using either of these methods. //L

How is that a fail exactly?

@MOOMISS1 I know right it's so awee

@panzuman Well according to bit[dot]ly/cGs1mI (it's a link, put it in your browser where links go, it's like tinyurl for Twitter) there's lots of different compounds in them besides CaCO3.

you might want an HD camera

Finding out that glow in the dark instead means you need a UV flashlight is like dating a women and you later find out she's a transvestite.

Should have read : A very simple way to make Glow in the Dark powder using Crushed Oyster Shells That doesn't work.

Most calcium, tide soap, white rock, (limestone) will glow in a black light..Your camera works OK. So why did you grind and heat it up? What a waste of time.

I know that Jesus Didn't eat oyster Shells he ate kosher Dietary laws fictitious Deuteronomy 28 & 30 Issiah 66 , i think that the gases that used in producing that oyster product that cover a intruder parasite that light reflective a is actually a softer version of its oyster shell , that covers the invader / parasite ,making the parasite into a pearl , you get the luminous color off the inside of the oyster shell called mother of pearl, and when people eat wrong /sin, those gases could work much like these are here to produce nails get to thick and other miss-calcification problems may very well be in that sin arise as their a little glow worm-testimonial to God Gospel validity , oysters are growing inside the shell people are not eat shell fish therefor I think oyster shell calcium sin with less glowing in the dark , i don't see people that glowed except for translation Jesus face shown with Mose and Elijah appeared with Jesus talking to him & Jesus was lighted , and these three men I believe they were not eating non- kosher diet , sin against Holy laws of God! God where are you ?
