OK, so I'm not a home brewer, tho I'm not adverse to the idea. However I'm working on a project that involves conditioning bottles and your fine site has come up on that subject more than most. I figure if anyone could help me, this community could, and it might help others too.
I feel as though I've done my due diligence in researching before posting but I haven't had much luck. I'm needing to de-label glass coke bottles so that I can re-label them. I've been able to work all the Mexican coke bottle easily, using paint stripper (although I intend on using the CLR method I found here from here on out). Those labels seem to be of the screen printing variety and come off relatively easily. Problem spots come off with a razor easily enough.
However, I recently made a trip to Costa Rica, where I found 1L glass coke bottles which are heavy and awesome. The problem is that, although they appear to be screen printed at first blush, none of the methods I've tried (paint stripper, CLR, muriatic acid) have made the slightest difference on the label. I soaked in CLR one night and acid the next to no avail. A razor just slides across it.
It almost appears as tho it is etched into the glass. Maybe etched and then glazed on? Has anyone heard of this? Is there any technique to remove it? Notice there's a rim of translucent but frosted glass around the red and white label
As you might assume, I only have a limited supply of them, not living near Costa Rica, and was hoping to utilize them both. For that reason I'm hesitant to attempt sandblasting the label off, although I feel like that would do it. But who knows. If I did blast it off, could I polish the area back to mostly clear afterwards? Im sure perfection is a foregone conclusion after abrasion. Any advice is greatly appreciated.
