Freezing




To prevent further damage such as bonding, distortion, deformation, corrosion damage, swelling or mould growth etc. from taking place it usually requires immediate freezing at a temperature of at least - 22º C. which secures the material. The time gained can be used to take a closer look at the damage and to decide on the next important steps.


Important
Freezing is not just freezing. This process needs to be quick, appropriate, technically well thought out and carried out in a manner appropriate to the particular material. Only when the material is frozen to the core will the damage dynamics be stopped. 

There are also materials, where freezing has to be used extremely carefully. If the material consists of e.g. specially decorated book covers (precious carvings, pearl embroidery, ivory or jewelled decorations) then a specialist should evaluate this type of material before freezing is applied.
