Does glycerin evaporate without residue? (Chem not my strong suit)

Not for a long, long, long, long time. You would just wash it off. Itâs soluble in water.

Itâll wash of easy like soap and it comes in food grade. - Rich

So would it interfere with the lasering process? Bubble? Spatter? The soap dries, so it would be different.

Weâre talking thin coat. I havenât tried it, but I would bet it would be better than using detergent that is designed to make loads of suds. Just sayinââŚMy advice is worth exactly what you paid for it.

Will definitely be following this! Iâve tried the Moly-D spray before with some success but it was time-intensive on the laser. I thought about cutting a mask on the metal part, spraying the Moly-D, removing the mask, and hitting it with a torch to âbakeâ it on. But, once @smcgathyfay does her tests, weâll know better!

Just got to the office to have a look at my can of Thermark.
Ingredients include acetone, ethanol, propane (spray can propellant), molybdenum TRIoxideâŚnot DIoxide, crystalline silica, mica, iron oxide, manganese and nickel.
I have some ideas on different mixtures to try that might work.
Any chemists want to collaborate with me? I got an A+ in Chem but that was 30 some years agoâŚlmao
I will apply with both airbrush and sponge. Hope to find good results

I donât think Chemistry has changed much over that small period of time

But oneâs working knowledge of it might.

I jokingly said the same thing to my girlfriend, who spends hers days in a research lab working towards a PhD in immunology (published article here: Risk Factors for Autism). She told me I was wrong.

HahaâŚthatâs fair.
Of course, I shouldâve known better to make an over-generalized comment like that on here. Though some of it seems like just the table âlayoutâ is constantly changing. But it seems like the theory of âelectron-pushingâ, to understand how reactions occur, and electron orbitals havenât changed much, if at all.
Itâs interesting they add molecules that only last a few seconds after some atoms are smashed in a lab. And, that they now give a range in which an elementâs atomic mass can range from!

Exactly!! Iâm sure I have forgotten more than Iâve learned in the past 30 years lol
First test.
TM = Traditional TherMark
A = molybdenum dioxide made into a slurry with perfume grade isopropyl alcohol and airbrushed.
Doesnât look like the MD works as well all by itself.
TherMark has molybdenum TRIoxide as well as lots of other ingredients.

I can certainly see a difference in density, but with the price differential it is still great for marking on metal. Perhaps not for commercial purposes but I would be satisfied for my garage uses.
Thanks for the test!

did you use dioxide or disulfide (which is what you linked to above as your purchase)?

I just failed Chemistry!! The original post was using molybdenum disulfide and yes thats what I was using for the test. I will edit itâŚthank you!!

Probably because thermark is more like enameling than engraving: http://www.thermark.com/content/view/16/86/

love this. I also searched alternatives and found Dry Moly as one of the b best alternatives. But it is so messy. My project for it is small so using a paint brush is exactly what I need. Love this. going to buy a bag and try it! could you possibly send me the link to yours, specifically? with all this counterfeit stuff going around (and Iâve been duped already) I much rather use your source since youâve proven it is the real deal. Thanks!
Me too.
But I notice that no one has considered saving the washings, and re-mixing them, if their cutting the cost to the bone !
