Thanks Rick, this was a big help to me when I was making toner transfer paper for PCBs.

Hide glue is made from ANIMAL HIDES. Otherwise known as skin glue. Its made by gentley simmering aimal skins in water for extended periods of time. Then its filtered poured onto a large lined baking sheet and allowed to solidify. This is broken into small pieces and spread out to COMPLETELY DRY. Once dry it can be collected and stored until its needed to use. In a metal glue hot pot sitting above a candel, some water and skin glue chips are added and mixed untila homogeneous goop forms. You have to use the glue while its hot and liquid. Paint it on both side of wher you want to make a join. Get pieces in place and clamp overnight. Next day remove your clamps and youre good to go. The interesting part about skin glue is that it tightens the joint as it cools/dries, and the bond is reworkable. Just steam it for a bit and the glue will soften and release. String instruments bodies are manufactured using skin glue, wood and shellac, an alcoholic concoction obtained from the Lac beetle, to seal the wood. No nails, screws or synthetic glues are used, as they interfere with the resonance of the instrument, whereas the skin glue resonates with the wood.

Just a suggestion man, but how about a slightly over sized piece plywood or something in between your oven and microwave. I was waiting on that oven to fall. Carefull my man. Cool video

Have you checked out boric acid to add it is an exclamation mold killer and bacteria preventer. And no odor.

Nice tutorial, thanks :) How long do you think it can be stored? You said a couple weeks (refrigerated) but is it like two weeks or up to a month or... And what if it's not refrigerated, will it go bad in a matter of days?

Could you give me the formula for making dexitrin adhesives in the production of bright red burning star particles in fireworks?

You can make glue out of wood to (the tar of the wood just burn the thing raw)

Makes no sense why you would convert the starch to dextrin and then add unreacted starch in the form of flour. It would be better to heat the flour in the water on a stove to release the starch and then add the dextrin to increase the solids content.

colspyro That works too. But the end product isn't the same.

my point is the flour adds nothing unless the starch`s molecular bonds are broken. Try sticking something together with flour mixed with water. Then boil some flour and water until it turns translucent and try that ;) The cornstarch should be treated with an acid catalyst before baking which will provide much better results and a higher solubility. The more dextrin you can dissolve in the water the higher the solids content of the glue.

@@colspyro could you explain me better? Which type of acid? Percentage? If I have 1kg of cornstarch, how much acid have I to put inside before bake it? Is it necessary to add "boiled flour" to the dextrin glue? Thanks a lot

@@leomaida92 Add 10ml (2 teaspoons) of 38% nitric acid to 430ml of distilled or reverse osmosis water. Incorporate the solution into the (1kg) dry cornstarch gradually in a large ziplock bag. Seal the bag and leave for several hours, ideally overnight, to allow the solution to distribute evenly. Break up any lumps by massaging the bag. When you are ready to bake the cornstarch, pass it through a coarse sieve or screen (16-20 mesh) onto the baking tray and bake in the usual way. You will need to pass the starch through the seive or screen a few times during the initial baking as it will tend to form a weak crust as the moisture is driven off. The finished dextrin will have a granular appearance similar to castor sugar. You can mill it into fine powder very easily (the grains are soft) but i prefer to leave it granular as its less messy to work with and is pretty much dust free.

Dextrin glue is not the same as hide glue which is an animal product.

I think he was meaning that the dextrin glue hes making is being use for hides thus the hide glue and not the brand
