Workshop: Building an Above Ground Pit

Above Ground Pit

Above Ground Pit

Recently we have been developing a traveling workshop..where we go to you, and work with you to build an above ground pit.  We first had to figure out how to do this because the soil here in Door County is mostly rocks with some dirt thrown in; in other words, not much top soil here.  We could blast but that seemed extreme, though interesting.  (A little northern Door history: many times orchard farmers would have to blast a hole to plant their apple and cherry trees, so it’s not as far fetched as you might think.)

So we experimented with the size of the pit and the gaps between bricks.  It took maybe a dozen firings before we were reasonably satisfied with our results.  In addition, we were also working out surface treatments.  Our goal was more color, though we appreciated the carbon black we got, we wanted more.  Greedy, for sure.  Good motivator.

Anyway, by the time September came around, we felt like he kinda knew what we were doing, so the whole process from the first class idea to the actual first workshop was only 9 months.

Recipes will be next.

  1. the fishies live in virginia, but would love to do this workshop with you. we have done primitive pit firing before, but want to build a pit or even an above ground pit in our yard. since you obviously can’t come here (though you’re invited!), is your material for the workshops for sale? the plans for the pit and the recipes? my husband promised to build me a pit before we got married five years ago, and i’d just like to help him along…

    i bet you’ve gotten this question a lot. i have a little book, but it isn’t very specific. and i’m a poet, not a sculptor, though that’s not true, it is true of my education. any help you have would be totally appreciated, mainly, at first, by my husband 😉
