She's been very excited and made a handful of pots already, but they don't seep as much water as we were hoping. Our guess is that there's a special mix of clay (including some straw that's burned out?) or low firing that helps the pot remain especially porous. Does anyone have experience with making these pots and like to share details? I guess we could of course ask the folks at the above website, but since they're likely to view it as somewhat proprietary, I thought I'd ask here first.
