Metal foils, tools, pigments), or with certain organic pigments and tannins, either before, during or even after their application. As you can see these are contradictory results which may be due to different preparation procedures, light source, exposure time, temperature etc. That matches what I understand elasticity to be. This article is over 3 years old of which many of the article has eluded my memory. Stir occasionally, to thin it add hot water equalling the temperature of the glue. These glues are sometimes applied because these tend to stick different materials together and are typically flexible.

Behlen, I also don’t know what type of hide glue they sell as there is a variety of low to high grade which I will go into detail later.

To make more homogeneous and complete sheets, I attempted to spread the glue mid-drying with a piece of stiff Mylar with some success. Cleans up with water best when glue is still wet. It appears new is nowhere as good as old, just cheaper. Isinglass naturally develops highly stable and elastic films if dried at room temperature, being slightly above its temperature gel. The viscosity that the manufacturer supplies is right for most jobs: Center joints, necks, blocks, linings, purfling. Gelatinous glues derived from fish have a low T gel due to their chemical structure, and cold set liquid hide glues, are convenient to use when long open times are required. I haven’t also located any of their products that indicate that they sell Isinglass. I used it in this instance because I could not fit any clamps on the glue blocks and the rub joint with protein glue was a perfect solution. We limit its use because it uses a lot of electricity but I recall how the laundry is becomes very moist during its use because of the high heat that it generates.
