clay or refractory mold is the only material i can think of that would work for repeated use.


In Topic: How Long Will Modern Pottery Last?

since we essentially duplicate the process of forming rocks, all of our ceramics is permanent and will be here until it melts again with some great force of energy.  maybe some sort of ultra hot explosion from warfare, volcano or lava flow, or perhaps heat from asteroid colliding with Earth.  with that said, there is a lot of terrible ceramics out there that will be here forever.


In Topic: Deflocculated Wax Resist?

i've never colored my wax, but sometimes add color to my glazes and slips since i'm colorblind and can't easily see some layers.  my recommendation in this case is to try powdered food coloring or powdered water color pigments (or even acrylic) - they work quite well, store forever, and will likely not have this issue.


In Topic: Using Wire Support To Make Spikes

yes, you can repeatedly apply/build up a layer of slip on a piece of wire (or even a nail) embedded in your clay.  the artists I know of who do this use something like a syringe or squeeze bottle to apply.  since the wire inside is rigid, and the clay needs to shrink around it, it's hit or miss in regards to the cracking you'll get.


In Topic: Help! Need An Oven Glaze That Is Food-Safe

I'm pretty sure to do the sharpie mugs, you simply draw on a glazed item and then bake it on - no messing with the underlying glaze at all, so not sure where you got the idea of the etching.  My wife did this with her class once and they all came out successful for what it is.  It's not "permanent" like true glaze is, it does come off with a good amount of abrasion, like even my fingernail if I wanted it off.  Other products to do similar things would be a Pebeo Porcelaine china paint pen, which is made to bake on at home oven temps - it is also not permanent, but I believe it's more resilient than Sharpie.
