CerMark alternative?

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


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


It’ll 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.

We’re talking thin coat. I haven’t tried it, but I would bet it would be better than using detergent that is designed to make loads of suds. Just sayin’…My advice is worth exactly what you paid for it. :grin: - Rich


Will definitely be following this! I’ve 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 “bake” it on. But, once @smcgathyfay does her tests, we’ll 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 TRIoxide…not 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 ago…lmao

I will apply with both airbrush and sponge. Hope to find good results :slight_smile:


I don’t think Chemistry has changed much over that small period of time :slight_smile:


But one’s 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.


The “Ether” and Earth are no longer considered elements.


Haha…that’s fair.

Of course, I should’ve known better to make an over-generalized comment like that on here. Though some of it seems like just the table “layout” is constantly changing. But it seems like the theory of “electron-pushing”, to understand how reactions occur, and electron orbitals haven’t changed much, if at all.

It’s 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 element’s atomic mass can range from!


Exactly!! I’m sure I have forgotten more than I’ve 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.

Doesn’t 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 it…thank 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 I’ve been duped already) I much rather use your source since you’ve 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 !
