Great lesson, I have done a bit of kiln casting, but always used a flask to contain the plaster / silica mix, the free form mold is a great take away from this lesson.

One question what did you use for grog?

Thanks

I might be more inspired if a different design had been cast. I found it difficult to "catch the vision" because it was difficult to pick out the design from all the clay and plaster.

Usually I enjoy your videos and find the material inspiring, but this one was lost on me. Probably my flaw :mrgreen: . I have no experience in this technique, and while I understood the process as described, it wasn't clear what you were trying to achieve in the finished piece. Even with the finished piece, I had a hard time discerning the design. Old age?? :geek:

Great introductory lesson on open face kilncasting. I have been experimenting with casting and this was a good lesson. However, I am looking for more relief and figure from this lesson I need to revamp my mold from one part to two part and my firing schedule to extend annealing to cover the thick and thinner areas. Any suggestions?
Thanks for the videos.

Hi Cindy,

We would need to know more about what form you intend to make before anyone could recommend firing schedules. Can you tell us more? Perhaps upload a drawing of the piece you plan to make? It would be important to know both the shape and the dimensions. Also, it would help to have a description of the kiln that you intend to use.

Happy New Year and thanks for the response.

The basic form is a fish in clay is about 1.75 inches thick and 9 X 10 inches and is shaped like a C (if that helps).
On a separate question how do you make those smaller hearts? They look fun.
Any chance of having a video on how to shadow say a tree with glass frit or inks?

Thanks,
Cindy

Hi Cindy,

In your planned 9 x 10" piece, what are the dimensions of the thickest and thinnest sections (let's call that the depth of the piece). Disregard the 9" height and the 10" width.

Hi Mary Kay,

I enjoyed the videos and tip sheets very much. I've been casting a lot with other cold material but I'll admit casting in a kiln is a bit intimidating ...at least for now, but the videos are reassuring.

One question though; Where can one find silica flour so as to add with the plaster?
ie; 295 mesh silica flour?

I'm in Canada so ordering the 40lbs Bullseye Investment (Plaster-Silica) from your store ( http://shop.bullseyeglass.com/bullseye-investment-plaster-silica-40-lbs-18-14-kg.html ) is not my preferred choice because of added freight and customs.

So if you have any recommendations it would be greatly appreciated.

Thanks again,
Serge

I don't know where to get it in Canada, but if I was looking to buy some here I'd go to Creative Ceramics & Glass because they are local to me. (Sonoma County, CA, USA)

It looks like they have silica flour in various quantities from 1 to 100 pounds.

Perhaps they can ship to you?
