A ceramic water filter is not a fine sieve with one hole size. It is fired clay packed with a maze of tiny channels 0.2 to 0.5 micron wide, so narrow that bacteria and parasites physically cannot fit through. That maze of pores holds the whole story of what a ceramic filter stops, what slips…
A ceramic water filter candle cannot fix bad taste in your water on its own, because the fired clay only handles particles and microbes. The compressed carbon core inside most modern candles is what scrubs chlorine, and knowing that one division of labor is the difference between a filter purchase that solves your problem and…
Commercial ceramic glazes from AMACO, Mayco, and Speedball are all formulated to melt into a glassy coating at specific cone temperatures, but they differ sharply in firing range, price per pint, color depth, and how reliably they survive repeated glaze firings in a home studio. This guide compares the three brands line by line, with…
Those tiny white specks on your fired bowl are not a kiln mystery. They are material lumps a 100 mesh sieve removes in about two minutes. This glaze testing guide covers the three habits that make fired results repeatable: making consistent test tiles, wet sieving every batch you mix, and measuring specific gravity before you…
Grog is crushed, fired clay that potters add to a clay body to reduce shrinkage, stop cracking, and help large work survive the kiln. The particles are hard, already-fired ceramic granules that do not shrink again when the clay around them dries and fires. This guide covers what grog is, how it works, its measured…
Cobalt carbonate is not blue in the bag. The powder arrives looking pink-lavender, and it only turns deep blue after it dissolves into molten glaze inside the kiln. That single chemistry surprise explains most color mysteries in pottery. This guide covers every classic ceramic colorant and oxide, including iron, cobalt, copper, manganese, chromium, rutile, titanium,…
