Personally I have a problem with horses finding them the least reliable of creatures fit only to be rendered into glue as soon as possible. The
reason for the headline is that I have reason to believe that this is not the case No PVA in Gloy). I'm not a chemist but why does PVA require a
preservative and a plasticiser? Is PVA not an adequate adhesive in its own right?

The my 'research' shows Gloy as a brand to be part of the historical record at least as early as 1918 and I suspect that PVA was not in the
mainstream of adhesive manufacture at that time. Could it be that the current Gloy has been re-engineered in recent years with modern
components ? The original ingredients would have deteriorated without a preservative I agree, but surely not PVA (unless the plasticiser is
corn syrup or something).

Any thoughts?
