Making methyl cellulose

Step 1 Assemble the tools and materials. They are: methyl cellulose, measuring spoons, stirring spoon, micro spatula, hot & cold water.
Step 2 Measure the methyl cellulose into a jar. The proportions for a pint is 2 1/2 tablespoons of methyl cellulose to 1/2 cup hot water and then enough cold water to make a pint (approximately 1 1/2 cups) We recommend using a good bottled water.
Step 3 Add the 1/2 cup of hot water.
Step 4 Stir briskly to prevent lumps.
Step 5 When the water is thoroughly dispersed add enough cold water to make a pint of paste.
Step 6 Let sit for several hours; preferably overnight. To thin, add a few drops of water, mix and let stand. Editor’s note: When ready to use place a small amount in another container. Never dip the brush into the main supply.This paste is archival and reversible with water. It is recommended for hinging small light weight papers because it has weaker bonding qualities than wheat paste.

This site is recommended as an additional resource on papers and hinging:
