You don't have to read all the pages but if you do have time, just add the page where you stop reading to your favorites so you can go back later.
Are you nuts? Maybe. Do you have any other questions about your mental health?
Go to the FAQ section where it has a lot of information. The FAQ link is just above the words "Hypertufa Forum" on the main page. Then if you have questions come back and post them. We can't help if we don't know what you're going to make, what material you're planning on wasting, what molds/forms you have. I think there's someone on this forum from the Arizona area. 105!!! Best temps for working with and curing cement mixes is between 50 and 80. There's got to be a way around the temps in your area so maybe someone here can help or talk to masonary supply house in your area. Work in an air conditioned house or in your car with the air turned up!!!! This is fun, anyone (even me) can do this, you can make some fantastic things. Billie

Oh Yes, I'd go for it and use that soak in a tub of water curing method!!! Go For It!!!

Well thank you both for your replys. I am thinking of going with the 1 part portland cement 1 1/2 parts peat & 1 1/2 parts perlite. I am planning on starting out with just a small pot first about cereal bowl size nothing very big. So I will need to do some soaking with this hmm guess I'll be doing more reading first he he. Yes 105 was yesterday and back in 1990 we had our highest temp of 120 so I am working in an oven so to speak.

pt, A cereal bowl size mold will cure fast. If you make this first thing in the morning, you'll be able to CAREFULLY unmold in about 4 to 6 hours. In your temps maybe sooner.
Don't forget:
Wear rubber/nylon/nitrile gloves whenever you work with cement. Even when placing and removing pieces from the water bath. Wear a dust mask when working with the dry ingredients.
Use a mold release (PAM baking spray works), just a thin coating. Have an extra mold ready in case you mix too much. I make pot feet or test tiles for leaves or anything you want to imprint with any leftovers
Thoroughly mix dry ingredients then add water.
After the mold is filled, place in a plastic bag, spritz inside the bag with a little water, knot the top of the bag to seal and place in a shady, cool location. If you use a garage or a laundry room in the house make sure you put something (old cookie sheet or plastic tub) under the bag in case it leaks.
If you are going to wire brush or carve the outside walls unmold as soon as possible. I unmold cereal size bowls in 4 hours. The walls have to be thick enough to carve. You'll have to experiment because of the temps that you have. Once this gets past a certain stage you can't easily wire brush or carve. You don't have to wire brush or carve, some people like the smooth sides.
As soon as you unmold place your mold in a bucket of water. Makes clean up easier. If an cement cures in the mold you can't use it for future projects.
After you're done wire brushing or carving rinse off with water and place in a bucket/tub of water. The next day change the water, it will be full of lime so wear your gloves. Rinse the piece off and add fresh water then do the same thing the next day. You should be able to remove from the water in about 2 to 3 days.
Remember when wire brushing or carving to be gentle the piece is fresh and can break easily.
Go back and clean your mold that's been sitting in a water bucket.
Wear rubber gloves. That slimy feeling on you fingers is your skin dissolving. Some people are sensitive to burning from the lime in the cement. Wear a dust mask when working with the dry ingredients. Full bags of cement weigh 92-94 pounds! Have fun! Billie
p.s. wear rubber gloves!
