Hi Timothy, Yes we tried to mix into powdered clay plaster, lime, also liquid glass within the water for mixing and the resistance properties improved. That was the reason for adding these additions. Even cover the exposed drying clay with a plastic cover to slow down the drying time further! Because the clay will deform a lot less, less bending and shrinkage cracks develop especially with bricks, or a larger bulky mass of made clay shapes.
If you are concern specifically about how many you can make if the clay dries slow, to remove the clay from a form simply make the form out of plaster nice and heavy and add metal rods in to make it physically stronger , then push the clay in and when full, turn the form upside-down and press on the ground onto a clean metal sheet.
Turning movements while pressing the clay down onto the surface so it sticks on well. This is very easy no worries. Stand on the edges of the metal sheet and pull the form upwards. The clay gets released easily from the day plaster mold. You can make several per hour this way.
When you plaster mold needs drying again you will see it will be harder to remove the clay from. Simply dry it on a sun or in a wind. Then you can continue.

Have you tried adding plaster and Sodium silicate to test your mixes — Na 2 SiO 3 also called water glass or liquid glass. You can mix it in a mix, also paint it on with brush or dip your fired items in it. If they are still porous clay, like firebricks and other low fired clay bricks for example chimney and fire place bricks for instance, the liquid gets absorbed into the body and protects then the hot face.
Sodium silicate can be purchased in liquid form or in white powder form for mixing with the clay or cement, Na 2 SiO 3 dissolves in water, stays clear like a clear lacquer.
Sodium silicate will nicely bind solids such as powdered perlite you use and withstands the high heat. Email me some pictures of what you do! Can any one help me.
