The study is aimed to find out if Hedychium coronarium (camias) flower extract is a feasible marker ink.
The ink was obtained b pondering camias flower petals through mortar and pestle, then filtered through cheese-cloth. Three media for writing were used: marker pen casing, marker paint casing, and improvised cotton medium. The ink was tested on common reporting papers, cartolina and manila paper. Using commercial marker ink as a control, the treatment was compared with the following qualities: intensity of color, resistance to fading, stability and overall acceptability. To give greater visibility, the group concentrated the treatment by heating over the flame.
The treatment passed the standards but only limited on papers due to its less absorbancy. Color- changing property was also present in the treatment that is absent in commercial inks. This will give an emphasis on important details on visual aids of reports. When subjected to acids, the ink changed from blue to red.
The group therefore concluded that camias flower extract is a feasible color-changing marker ink for papers.
