Has anyone actually done the stencil with wax covering the glass? I know it was mentioned at several points as a good option in this thread, but noone followed up with results.

If anyone has done it a good step by step would be greatly appreciated. I would like to do my brewery name/logo and graduated markings on my carboys and I think that would give the best results if it works.

Same here, those pics are of my primary and I like having volumes marked so I can add top-of water when I do a partial boil, etc...

Saw this thread earlier today and figured I'd give it a try. Turned out okay, just a few spots that didn't get covered thick enough in the etching gunk. I'll probably be doing a few growlers with the brewery logo as well. Happy with the results. Thanks for the cool idea.

Very nice etching job there Freddyb. I may have to use it as a guide.

How long did you leave the acid on for?

Now that's one cool looking etching job, best i've seen so far, congrats bro.

I have 10 gallons of green industrial diamond grit once used or blasted but afraid to use with a thin rubber mask as the diamond will eat away the carbide nozzle of the sand blasting unit I have. It's a syphon pot like a old spray gun unit. Even with once used diamond at a smaller fractured diameter it will still eat into glass if held too close and long. I let over 3,000 pounds of used diamond grit get away can't pack rat away everything from job sites. It was used on stainless lap pools at a sports club as a safety law stated brushed stainless was a hazard. They blasted two pools and epoxied them light blue. They could only use the diamond one time and trash it into dumpsters. Dumpster diving me got 10 gallons. Coins in a rubber tumbler will eat the coins into dimes, don't ask.
Is a neutralizing agent needed after washing off the etching paste?
I have diamond blasted gallon marks into the inside of the MLT as well the boil kettles, no more dip stick readings as well any hidden bugs in the frosted gallon lines.

slightly OT maybe, and apologies in advance if so, but since we're discussing marking..... How do you guys mark your stainless boil kettle? I just have a plastic (HDPE) dowel with marks on it I use.

Thanks. I brushed multiple layers of etching compound onto the carboy continuously for about 5 minutes. Then I waited another 10 minutes before starting the water rinse. Make sure to lay the stuff on thick. In hindsight, I might have gone a few minutes longer. I'll experiment a bit on some growlers.

According to the instructions, a thorough rinse with water is required. No additional neutralizing agent is mentioned. I rinsed for at least 10 minutes before removing the masking and then for another few minutes after just to be sure that there was no remaining residue.

This sounds like a great idea! I don't have much confidence in my notched plastic spoon as a volume measurement device.

I used that thin surgical rubber sheeting sand and grit blasters use for glass frostings on the inside of my last brewery I sold. The MLT and Boil kettle were marked with this same diamond grit. I mentioned this last year on this forum.
I was hammered as this would collect nasty bugs, come on just a frosted finish
not 36 grit or a a concrete finish on the stainless. On the boil these were made as hot level marks to get the proper cold gallons for the fermenter, it adds up when your adding 16 1/2 gallons into the fermenter for 15 in the corny's.
