One of the most enduring questions in history is how did the ancient Romans and Egyptians created the first known glue? This is an age-old question that still provokes a lot of interest today, especially with the newer invention of Metal bonding adhesives like the ones from CT1, that have replaced the need for drilling holes and using screws to join metal pieces together.
The earliest idea about how to glue was created comes from the use of sticks. People would use these sticks to stick items such as nails and other materials. Another theory that has been proposed involves the use of vine leaves and twigs as materials. When these materials get wet, they would start to form a glue like substance. However, there are also people who suggest that molds were responsible. These theories all have varying degrees of truth, depending on the specific circumstances surrounding the discovery of glue.
There are a few other theories surrounding how glue was made, before the discovery of metal. One of these is that bees would form glue from wax. Another idea is that glue was created by adding fat to test whether or not it would work as an adhesive. All of these theories have gaps in the evidence and none of them are backed by hard facts.
Regardless of when and how glue was first created it has become an invaluable tool for humans to use in the construction of many items.
