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.

In Topic: How To Slab A Round Cylinder

any smooth-sided cylindrical form on the inside (cardboard tube from paper, sonotube for casting cement, PVC, ABS, anything...)

roll out slab with machine or make by hand, put layer of newspaper between clay and form to prevent sticking and to aide in slipping it out.  cut a straight edge on slab, then roll it over form (like how you pickup up dough with rolling pin) to make slight impression where the seam will be - then cut both ends at a 45* angle so you get a nice flat seam with most surface area for good contact.

the tip Marcia gave regarding cradling the slab with tar paper is a good one - great for when you cannot roll the tube over the slab and need to apply it to a vertical form.

In Topic: Reconstitute?

glazes/underglazes don't really "go bad".  reconstitute and use them!


if they're hard-panned in the jars, try a loop tool to break the material up and then blend it with blender/stick blender.

In Topic: Making Multiples Of A Print On Clay

a screen making alternative -- screen printing film.

there is a printmaking class at my wife's HS and I always thought the students were making screens with emulsion, only to find out they are using some modern screen printing film.  basically it's a transparent plastic film that they hand cut with razors.  lay film on pre-stretched silk screen, then use this solvent/activator that fuses the film on the screen.  it's quite genius stuff and is very quick to do.  lasts just as long as traditional screens.  sorry, don't know the exact product name.


in our studio we use a Riso machine - basically it's a thermofax screen maker.  make carbon-based photocopy of image (laser printer or copy machine), layer the ink-side against the thermal screen, run it through the Riso/thermofax.  the plastic on the screen fuses with the ink, then you peel it off and are left with a clean screen to print with.
