The mark consists of the literal name of a product "TephraPro" in black in the middle. Below the name there are three grey lines that represent materials coming up from below, one from the left, one in the middle and one from the right, meeting in the bottom middle of the name. Above the name the lines are coming out the middle of the name and are spurting out of the top as three red lines, one to the left, one straight up, and one to the right. The logo represents a volcano with lava gathering up out of the ground and ejecting materials, tephra(rock fragments and particles ejected by a volcanic eruption), out the top. The lines are not straight lines, they are a bit narrower in the middle of the logo and are wider at the ends, like fluid is being gathered to a middle point and coming from a middle point and dispersing as it is ejected out the top.
