The methods of application — by Polish and Soviet research workers ■— of methyl-cellulose for strengthening old paper of historical value are described. The author’s own investigations aimed at determining the usefulness of various types of methylcellulose in conservation practice. The tests concerned were made with both new and impaired paper i.e. that subject to the process of artificial aging. Their results have shown that the applied kinds of methyl-cellulose exert a positive impact on enhancement of the strength of new paper and that subject to aging at 105°C. If the temperature of 165°C applied, the effects are less satisfactory. Good results have been obtained with Tylose C-300 and C-600 employed for the strengthening of impaired paper. Moreover, as has been ascertained, the said agents also have protective properties.

The article discusses the features and use of artificial resins obtained by ethirification of cellulose. Apart from the two generally known and frequently used ethers: methyl cellulose and carboxymethyl cellulose, other ethers were pointed out, such as ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose and benzyl cellulose. The commercial names and names of producers of the more important cellulose ethers were given, with literature concerning their use in the conservation of paper, natural fibre fabrics and paintings done in distemper.

The article contains a review of glues presently applied in workshops dealing with the conservation of objects with paper bases. The author discusses assorted properties, merits and faults; he also indicates the most important usage of particular glue substances. Considerable attention is devoted to natural glues, traditionally employed in work with paper, such as paste, and gluten glues: gelatin and leather glue, as well as parchment glue and others. The article mentions preparation for work, as well as the properties and application of cellulose derivatives: methyl cellulose, carboxymethyl cellulose, hydroxypropyllocellulose, and cellulose acetate. The article also lists synthetic glues.
