"IIRC, Vogue discs are not lacquer, but vinyl. According to http://voguepicturerecords.org/records.html: "The records were produced using a complicated process whereby a central core aluminum disc was sandwiched between the paper illustrations and vinyl.

So it may not be as risky as lacquer to find the right treatment."


I think the main thing is investigation and strategic spot testing before treatment for each new case which is what I think Bryce is also getting at, that is the major caveat with trying previously unverified processes for a specific materials instance, not just going for it, so to speak. With lacquer discs and perhaps this case, I would have special concern about the spindle hole as a potential problem point for moisture. That is one of the nice aspects of having trimmable materials being used that can be custom shaped for a need, especially if the solvent use is for any duration. Part of the reason the goretex method worked well is you are spot humidifying as opposed to wetting which may be more invasive on the paper material or ink, and we wanted to save the labels in good condition and this process basically just allows the label to be lifted off after treatment (if water soluble adhesive was used. discovered via test), as part of preserving the entire disc and label.

Although hesitant, I wanted to mention what we had done in a little detail because it's not something we've shared much, but could be a useful launching point for someone else.
And, of course it's always nice to practice on something replaceable first.

Best,

The caveat (first) is that there are different types of adhesives, some are water soluble some are not, which is what Bryce is getting at I am guessing. In our case we have used the process to remove lacquer disc labels affixed with water soluble adhesive that feature non-water soluble ink when the label covers grooves. There is a gore text sheet that can be trimmed and damp blotter paper against the gore-tex. It is similar to the damp blotter pack on this page: https://www.conservation-wiki.com/wiki/PMG_Humidification,_Drying_and_Flattening. We used reverse osmosis water. One can also use mylar sheet trimmed/with cut outs, over the gore-text (or under) to targer specific areas. There are some different concerns than when applying it to disc as opposed to photographs, but  the cons section is relevant, including the one:
>
>"Empirical knowledge and skill are needed to create the perfect balance of humidification within the packet for photographic materials. Too little water in the system and the photograph needs long periods of time that may be detrimental to it. Too much water in the system and the photograph can become too saturated or wet with water, beyond dampness."

>The "pack" can be trimmed and sized only to apply it to the spot where it is needed which is a plus when it comes to introducing any moisture to a laquer disc.

>Before using, it calls for targeted testing of the disc (and other materials in contact wit the) surface, although knowing vogue discs, the surface is pretty durable and there are many issues/copies of them out there (generally).

>IMHO, It may not be worth the time required, unless there is something particularly unique or special about the disc. But it may be an opportunity to test process. We developed/used it for laquer and very rare discs that were in good shape and featured no cracking. Even with water soluble adhesive it may need to set for several hours to possibly overnight (in our experience).
