Terra Sigillata

Today I made a batch of Terra Sigillata. To be accurate, I made it yesterday and harvested it today.


I've been wanting to test some slip on raku ware. I made some small test plates with slip in the middle. My plan is to cover the slip with a copper black glaze and put a copper/green glaze on the remainder of the plate. I hope to fire this in the next couple of weeks. I will post my results.


I threw a stoneware plate and once again put some slip in the middle. This time I put a layer of helios (porcelain) slip with red iron oxide around the remainder of the plate. Not sure which glazes I will use on this one.


I've discovered when applying slip a little thick (as in the photos above), you must do the following:

1. The slip must not be too watery, and
2. You must dry them very slowly

Otherwise the slip will crack.

I recently purchased a couple of paint sprayers and I am about to get into spraying glaze. Until now I have only dipped and brushed. My friend John Tilton is going to give me a few tips this week at his studio. I'm looking forward to it!

That's it for now but there are currently a lot of things taking place in the stuido. There should be more postings very soon. Thanks for reading!
