Talk:Conservation-restoration of the Shroud of Turin

Horizontal storage.
When did the shroud go into a climate controled case?

Has anyone considered that the isotopes of carbon are heavier; hence CO2 with heavy carbon might be more likley to be in contact with the bottom of the case?

Also H2O plus CO2 does prodice an acidic properties which can reduce or acrete the shroud. The carbon infiltration appears poorly understood by all. Dry wood is 20% water not because the atmosphere is 20% (at 90% humidity) but because water is sticky. VOCs are sticky, and particularly in the presence of other materials which can absorb them. Even graphite is sticky with water. The effect is that the shroud simply gathers fresh carbon all the time from exchainge with the air. — Preceding unsigned comment added by 72.94.236.35 (talk) 12:57, 3 May 2015 (UTC)
