The Limit of Heat
Solar Terms is one of the 713 brands in Inktend's built-in ink catalog.
Paper & pairing
Reds and pinks show the most dramatic shading of any color family: expect real variation between the edges and center of each letter. This ink will behave predictably on most fountain-pen-friendly paper. Cheap, highly absorbent paper (standard copier paper) will dull any ink's saturation and can cause feathering or bleed-through with wetter nibs.
About Solar Terms
Solar Terms is a Chinese fountain pen ink range of 24 colors themed on the 24 solar terms of the traditional Chinese calendar. The series is associated with the long-established Chinese ink maker Ostrich and is sold in small 15 ml bottles, mainly through online marketplaces.
Storing and using the bottle
Bottled fountain pen ink has an effectively long shelf life when kept capped and out of direct sunlight: most inks remain usable for years. The main risk isn't the ink spoiling, it's a pen sitting inked and unused for weeks: that's what causes clogs, not the ink's age.
