Acidic surfaces wood with dark tannic acids, some leathers and metals can inhibit curing of the Instant Bond adhesive. Admittedly deep inside a Pyramid is pretty Titebond Liquid Hide Wood Glue Zip stable in both temperature and humidity. There are many more advantages and reasons that I love this type of glue, and reversibility is definitely high up there. It softened enough that I could squeeze the ball bearings back out, but what remained was a honeycombed, spongelike titebond liquid hide glue drying time deposit of rubbery aliphatic resin that looked like a coral reef — and that hardened up rock solid again as soon as it dried out. Some years later I was able to afford a real pencil holder, so I transferred the pens and pencils and filled the old jar with hot water so as to melt the Titebond and reclaim the ball bearings.

Hide glue has been around woodworking since it began. Why, then, would woodworkers insist on using this glue?

The main reason in modern times is reversibility. In woodworking shops during the 19th century, woodworkers discovered a secret to working with hide glue.

If you added urea a high nitrogen compound used primarily in fertilizer today to animal protein glues of which hot hide glue is but one , you could lengthen the gel time of the hide glue, or keep the glue in a liquid state much longer, thus allowing more intricate work to be completed before the glue set. As we moved into the 20th century, woodworkers and manufacturers understood how additives could affect the properties of hide glue even more.

In the s, anti-gelling agents were added to hide glue and the result was products that could stay liquid at room temperatures and achieve a slower set time but continue to be totally reversible. A point to be made here is that these additives all reduce the strength of hide glue.

But that is not a critical issue due to the fact that liquid hide glue, although slightly weaker than hot hide glue, is still stronger than the wood itself. Jump ahead some 80 years and today we have two primary manufacturers of liquid hide glue. These glues have similar working properties and both provide sound a glue joint for furniture conservation or construction. Old Brown Glue is a mixture of animal collagen and urea with no other additives. Titebond Liquid Hide Wood Glue lists cyanoguanidine used in the manufacture of plastics and pharmaceuticals and ammonium thiocyanate used chiefly as a herbicide and in textile printing.

Old Brown Glue appears opaque or cloudy when squeezed from the bottle, and getting it from the bottle is no easy task when the glue is at room temperature.

Additives to the glues make the Titebond product left transparent while the Old Brown Glue is nearly opaque. Editor Christopher Schwarz, an ardent user of Old Brown, simply deposits the bottle into a pail of hot tap water. After a few minutes, the glue is ready to use. Titebond liquid hide glue, when dispensed from the bottle, is very clear, almost transparent. How will your nose react to these glues? We often hear woodworkers disparage the smell of hot hide glue.

But does the liquid version of this smelly adhesive possess the same attributes? We blindly tested the smell of the two glues within the Woodworking Magazine shop. What we discovered was a landslide winner — if you can call it a winner.

Every member of the staff chose the Old Brown as the smelliest. Interestingly, after we finished our non-scientific poll, we found that there was a tie in the race for the most-smelly glue. Non-woodworkers, for the most part, preferred the Old Brown smell and found the Titebond glue more offensive. More Interesting Comparisons A rub joint, wherein you add glue to two pieces of wood and rub them together until the glue achieves its initial tack, is a benefit of hot hide glue.

So, we tested the initial tack with the two glues. The Titebond product had virtually no perceivable tack. When the Old Titebond Liquid Hide Glue Review Number Brown product was rubbed, you could immediately feel a tack in the process.

No, there was not the same tack as with hot hide glue, but you could feel a slight grab as the two pieces were joined. Score one for Old Brown.

However, we remembered that the Old Brown glue was heated and wondered if that preliminary tack was due to the glue gelling as it cooled. To keep the test equal, we heated the Titebond glue and performed the same test. Our original findings held. The Titebond glue exhibited less tack than was found with the Old Brown Glue. The Most Important Comparisons Smell, color, transparency and initial tack are notable characteristics of these two liquid hide glues, but the important features are how the glue joint holds up and what it takes to reverse glued-up joints.

The holding power of the glue joint is of primary importance when building or constructing Titebond Liquid Hide Wood Glue Man a project. If you experience failure, your project is nothing more than a pile of sticks. There are two types of failure as shown in the photo below.

The first is glue failure the left-most pieces , where the glue bond fails and the two pieces come apart directly on the glue line. A second failure is wood failure the right-most pieces in the photo.

This is what you hope to find if you have a problem. A wood failure means that the glue bond held and the wood itself gave way to stress. While this is not something you wish for, it happens to a single joint, for the most part, and not throughout your project. Pieces on the right side, with ragged edges, clearly show wood failure. To test the glues for failure, we assembled 10 sets of joints using Eastern white pine, five joints per glue. When a dried coating of Titebond Liquid Hide Glue is painted with a latex paint, the Hide Glue absorbs much of the water from the paint.

As the surface of the paint is drying, the Hide Glue is swelling or stretching from this additional moisture. The swelling of the Hide Glue effectively "pulls apart" the top coat of paint. As a result, the crackle effect is achieved. Instructions Crackling will work on virtually any surface.

The most successful working material is wood. However, the crackling process will occur with metal, glass, rubber and plastic. Some surfaces may require a sealer. Choose two colors of latex paint.

Water-based paint must be used. One color should be lighter than the other color. Choose one color as the base coat. The topcoat will be the predominant color of the finished piece. Coat the piece with the first color and allow to thoroughly dry. This will be the color that shows through the cracks. Apply an even generous coat of the Titebond Liquid Hide Glue.

Make sure that the piece is covered completely. Allow the piece to dry thoroughly.
