I have a small graphic stamp made for me by Mel Jacobson years ago when he was teaching a workshop that I attended and we became good friends. At the time I was signing using my first initial and last name. His comment to me was it doesn't have to say your name per say, if the work is good enough the simple stamp will say it is you. Of course, this is coming from Mel who is very successful.
This has always been a little perplexing to me because needless to say, this is all well and good, but I am not as well known as Mel.
This all said, I did go on and when making clay pot cookers, I signed my initials and sometimes my initials and the stamp on the lower outside foot of the piece.
I am now doing sculpture. These pieces are not large, maybe 10" tall and do not lend themselves to a signature per say. I have gone back to Mel's stamp and use this as a stamp of signature as well as an adornment.
As you can see, this is an ongoing perplexing issue for me as well.
Like Neil said, just about anything organic can be rolled in/burnished in/pressed in, then either removed or burned out. Other stuff I've used and liked (but it may HAVE to be removed before firing) includes rocks, onion bags, highly textured fabric, rope, stencils, old computer parts, scraps of packing material, old crochet doilies... your imagination is your only limit!
A couple of years ago I had a potter friend in my house. She picked up one of my bowls and commented "This feels perfect, it makes you want to pick it up." I took this as the ultimate compliment. Though I am not throwing any these days, but doing midsized bust sculptures, I still apply this same desire with each piece. I want it to wow me. I am hoping if I accomplish that others will see the time felt love that was applied.
Thanks BigDave. I thought paper clay was great for sculpture for two reasons. First being as stated in the clay descriptions, is low shrinkage, but second an incredibly smooth texture for good fine details like you naturally get with porcelain. The grog confuses me. On this same note, what is B mix? Thanks for your patience. Sandra
