Methyl Cellulose is on a par with wheat starch paste in its usefulness to conservators. It is most commonly used as an adhesive, which is both reversible and water soluble, though not as ‘wet’ as wheat starch paste. It can also be used in a poultice form for removing spine pieces, and is regularly used for consolidating paper edges, where they may have lost strength over time. In each case, the material and media must be tested before MC is used.
This particular recipe is used at the V&A to make MC that can be kept for a month or so, out of the fridge.
