“The medium for binding distemper is known as “size,” or sizing. For making it, gelatine is preferred, although the best grade of White Cabinet Glue answers very well and is most commonly used. Drop four or five pounds into the cauldron, cover it with water, and fill the water vessel two-thirds full of water. Apply the heat, and when the glue is melted you will have extra strong size. One dipper full of strong size with four dippers of clear hot water will produce working size.” Excerpt from Frank Atkinson’s “Scene Painting and Bulletin Art” (1916, page 154).
Advice from Wendy: My glue supplier is Bjorn Industries out of North Carolina. I have discussed my need for animal glue during restoration projects with their chemist and we decided on their product HC351. Rabbit skin glue is my second favorite to work with as an alternative. Also, NEVER put size water in plastic – only metal or glass. Also, do not seal the jar, cover loosely. Otherwise, you create your own little science experiment, allowing the glue to begin a rotting process.
