Tile Flashcards
surfacing unit, thin.
made from clay, or mix clay/other ceramic.
glazed or unglazed.
fired above red heat, produce specific physical characteristics.
ceramic tile:
glazed or unglazed,
usually ≥ 6in2,
made by extruding natural clay or shale.
quarry tile:
formed by either dust-pressed or extrusion.
1/4in to 3/8in thick,
facial area ≤ 6in2.
ceramic mosaic tile:
process:
large presses shape dry clay.
dust-pressing
machines cut from wetter, more malleable clay,
extruded through a die.
extrusion
classification:
in US, based on
size
classification:
imported tile, based on
production method,
water absorption,
finish,
glazed/unglazed.
4 US classifications:
mosaic: < 6sqin
wall tile: > 6sqin
quarry tile: extrusion
paver tile: dust-pressed and > 6sqin.
tiles often classified by resistance to
water
nonvitreous:
absorption >7%.
semivitreous:
> 3% but <7%.
vitreous:
> 0.5% but <3%.
impervious:
≤0.5%
classifications of abrasion:
group I–groupIV
group I: light residential
group II: moderate residential,
group III: maximum residential,
group IV: highest abrasion resistance, commercial.
