Definition
Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

Etymology
From German Tachylite, from tachy- + Greek lutos soluble, melting
From Latin conglomeratus, to roll together, i.e. from com together + glomerare to gather into a ball, from glomus (genitive glomeris) a ball

Formation
Tachylite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

All about Tachylite and Conglomerate Properties
Know all about Tachylite and Conglomerate properties here. All properties of rocks are important as they define the type of rock and its application. Tachylite belongs to Igneous Rocks while Conglomerate belongs to Sedimentary Rocks.Texture of Tachylite is Vitreous whereas that of Conglomerate is Clastic. Tachylite appears Glassy and Conglomerate appears Shiny and Rounded. The luster of Tachylite is resinous while that of Conglomerate is dull. Tachylite is available in black, dark brown colors whereas Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. The commercial uses of Tachylite are cemetery markers, creating artwork and that of Conglomerate are cemetery markers, in aquifers, tombstones.
