Picture Credit: The Color
Propolis has many colors. The color depends on the source of propolis and the season of the year. It ranges from yellow to dark brown, depending on the origin of the resins.
In fact, transparent colored propolis has also been reported. So don’t be surprised at two propolis that look very different.
The Characteristic
In warm weather, propolis is sticky and soft. But in cool weather it hardens and becomes brittle.
If you store your propolis at lower than 15 C or at a nearly freezing temperature, it will remain brittle, even after you heat it afterward.
At normal room temperature ( 25 – 45 C), propolis is a soft, sticky and pliable substance. As the temperature gets warmer (above 45 C), it will be more like a glue – gummy and increasingly sticky. And at less than 15 C or near freezing temperature, propolis will harden and becomes brittle.
To change propolis from from solid to liquid, you need to heat your propolis at around 60 to 70 C. Some propolis, however, will only melt at 100 C.
