tecpaxalli (FCbk11f216r)
This compound hieroglyph features ground flint (tecpaxalli), a powdery substance used for polishing. The term selected for this example comes from the text near the image in the Digital Florentine Codex. There is no gloss, per se. This compound has two elements, a flint knife (tecpatl) that is standing on point, with a dividing line from top to bottom, dark in color to the right of that and light to the left. This element provides the logogram for the start of the word, tecpa-. Below this weapon or knife is a cluster of grains of sand (xalli) and small rocks, which provide the -xalli ending for the term. The text explains that this powder or sand is a medium for “cleaning, polishing, thinning and scouring” (drawing from Anderson and Dibble’s translation).

This is one of several ground minerals that were used for polishing. Other examples in these pages of the Florentine Codex include tezcatlalli, temetztlalli, amochitl tlalli, etc.
