Ah, that makes sense. Thanks. By any chance, do you have any suggestions on the power/CFM necessary?

Hi, I want to build a spray booth in my basement studio. The design I have in mind would have a spray area 36" x 36" x 36" max, with a filter at the back and a fan behind the filter. The fan would then connect to an exhaust hose and vent outside through a basement window directly above and behind the booth. I have some questions about the fan: (1) What is the best type of fan for this setup? (I was thinking of an inline duct fan?) (2) What is the minimum CPM I should look for in the fan, especially if the air passes from the fan, through an exhaust duct, then outside? (3) As an

Hi, I have a related question. I can see how throwing round plates is faster and easier than slab building. But if I want to make a large, rectangular or oblong platter (e.g., a 9" x 21" fish platter), would it be easier to do that using a hump mold or a slump mold? My initial guess is that a hump mold might be easier because you can let it dry on the mold and gravity will help the curved sides keep their shape. However, I've never used either a slump or a hump mold before, so I might be missing something.

Thanks mugmkr. This definitely a great starting point, and the small batch size will make it easier to experiment with. Enjoy the snow—it sound beautiful!

Thanks for the help! Chilly, that's exactly the kind of thing I was looking for.

That's why I asked for a ratio of clay/water/deflocculant. If you say add 0.01mL for 0.5 pints of water and 1 lb of clay, I can adjust accordingly. I will need to make a new batch, so I can start from whatever ratio you provide. Thanks.

Thank you both. John, can you recommend a clay:water:deflocculant ratio? I have some Darvan, but the I read that if you use too much it can have the opposite effect, so I am not sure how much to use to create a workable thick slip. Casting slip seems too thin...

I'm trying to add some decoration to my pots by applying slip. For example, I throw a pot, slather it with slip, and then run my fingers or a rib through it to create texture. The trouble is that once the clay dries and the water in the slip evaporates, the design does not stand out from the surface very much. Is there a way to create a thicker slip? I am currently using Standard 365 porcelain and I make the slip by adding just enough water to my trimming scraps that I can get a smooth paste by running through a sieve. Thank you.
