The Ultimate Amber Teething Necklace 1. Take a few drops of acetone (fingernail polish remover) or alcohol and drip it over the surface of your piece. If the surface becomes tacky, or the fluid takes on the honey golden color of the substance, you can bet it's not amber. 2.Amber does not melt. It will burn away like incense. 3.Amber is buoyant in salt water. To do this test, mix about 1 part salt to 2 parts water and dissolve the salt completely. 4. "Hot needle" tests- the most effective. To stick a heated needle into an imperceptible place in the amber (a hole of a drilled bead, etc.). If you smell definite pine-tree resins it means it is real amber. 5.Heat treatment. All natural amber contains microscopic bubbles. When you apply heat to a single piece of amber, these bubbles evaporate and the amber becomes transparent. The greater the temperature, the darker the amber will become.
