Matt And Dave’s Clay…

A while back Matt sent me some of Matt and Dave’s Porcelain For The People and I did a post about how I thought it threw. Although a bit different from the clay I’m used to which I would expect with any new clay, my overall feeling was that it was an excellent throwing porcelain. That being said, it was only a relatively small part of how I abuse clay so I withheld judgment until it went through the gauntlet. I decide to beat the hell out of it (at least metaphorically). First, it was thrown thin and then the foot trimmed just as I always do. Then I put on a layer of resist and usually I’m pretty gingerly at this point because I’m not trying to etch it too deeply because I know I’m gonna etch it again and the pot isn’t thick enough, but in this case I really etched it quite deep. I was trying to find out how the resist held up and how the clay responded to “hydro-abrasion”. Two big thumbs up here as it worked very well on both counts. Then after drying completely, I applied more resist and did it again and still it held up extremely well, in fact some areas that were left were extremely thin, maybe 1/16″ – 3/32″ in places. I felt this would be interesting when I gripped the bisque pot with some glazing tongs. After the bisque, the pot was a bright white, even a touch brighter than what I currently use. For glazing I dipped it once, then applied wax all over the piece, wiped away the exposed areas and redipped again after drying. It was fired to ^6 and down-fired to 1500 degrees F. I have to say that Matt and Dave’s clay’s performance was excellent during the entire process. Here’s several pics of the same pot…






Photography this week, which I hate but it will be nice to get it out of the way and upload some pots to Etsy.

    Very cool. I’m especially impressed by the rings inside the bowl…I wish I had such a steady hand! You usually fire to Cone 6, yes? I was curious about Matt & Dave’s promise of a cone 6 porcelain. Is this what you tested or is this the cone 7-10 clay?

    looks great! I didn’t know you had an Etsy shop!?

    The clay is very rugged at cone 6. The reason why we classified the clay at cone 7-12 is because although the clay works well at 6 it is not quite matured to where I like it a cone 5. A lot of people use cone 5 and cone 6 pretty interchangeably. As a Ceramic Engineer I am not comfortable with this, as they are two distinct temperatures. So to prevent people buying the clay, firing it to cone 5 and coming back with complaints of it not being mature enough. I changed the general definition to cone 7-12 (but it does very well at cone 6).
    The dedicate Mid temperature (cone 5 and 6) is in testing right now. Matt

      Thanks Matt for your reply (and Jim for the reports!). I’ll be curious to try your clay once I’ve finished my glaze testing.
