    No need to apologize! I too am pretty new here and was asking the same thing a few weeks ago. It's a big benefit auction for the National Sarracenia Conservation where members (and others) put up plants and other goods for auction and the proceeds go towards protecting land and other good causes. There should be a bunch of great plants/other stuff up for auction. I believe it starts on the 30th.

    *edit* Oops NON beat me to it.

    I'm sure I could make a set of planters with inscribed/carved cps on the side. Raw clay on the inside, porous non-toxic high fire glaze on the outside!

    That would be sweet! Some cool sgraffito would be awesome! Although I've heard you want ceramic pots for CP's to be glazed on the inside as well. Otherwise minerals from the clay could be detrimental when they seep into the soil after waterings. So I hear..

    I've heard about that as well. Though I've discussed with very serious and experienced Flytrap expert Steve Doonan, arguing your point stated above. It appears that high fire clay has incorporated all materials including minerals as the glass form of ceramic. Ceramic is a true glass, and straight out of the kiln, it is practically sterile and inert. Whereas glazing on the inside with certain materials will eventually leach. Glazes that contain barium, cobalt, iron (low fire) etc. are toxic and leak quiet a bit. There are some glazes that are safe on the inside, but I figure leaving it raw takes out the guess work and allows the soil to stay a bit cooler. I've not seen extreme evidence on either side and I think it depends on the clay, technique, glaze, and kiln temperature. the setup at my school is high-fire reduction, perfect for plant pots.

    Outside of this hobby, lower fire, softer, porous glazes are preferred as they allow the most breathing and organic/rustic aging on a pot. These are excluded from our hobby because the raw clay does leach because not all of it's content is true glass.

    Beautiful artwork! I do ceramics in school, and have tried my hand at throwing, but I'm much better at hand-built. I've made pots that look like pitcher plants, and many other sculptures and such as well. I envy those who can throw well, though.
