So what is the recommended sand for a beginner to use?

I have been doing some research and it seems you get better results with a oil based sand. Petrobond is the most popular but other than not having a local source I read it really smokes.

Then there is K-Bond which seems promising. I can acquire the ingredients and mix it up myself.

For mixing it, is sand Muller required or is there some other trick?

I have been teaching in schools for some years and some use a water bond sand and others use an oil bond (Petrobond) sand.

The advantage of an oil bond is that once the mold is made it can be set aside for maybe a week until a pour is done. A mold done with a water bond sand is like a giant, tight sponge. It will start losing moisture from the time you are done ramming. After a few days it may have dried out enough that the inside can begin to crumble. If you bump it, it may crumble more. Finally poured and the pour doesn't come out right due to this collapsing.

Oil bond sand won't do that. It can crumble due to impact, but it seems to hold together better. It does not dry out.

As for smoke, during the pour (in my case aluminum and bronze) there is very little. If the mold is left to cool completely (say over night) then upon breaking it out there is also no smoke. If you have to break it out after 30 minutes, there will be lots of smoke. I have broken castings out after 10 minutes on to an iron table. The piece and the sand is so hot that the oil spontaneously combusts. It was not violent, but it was impressive. I would expect almost everyone here doing any pouring is going to do it outside in fair weather.

Mixing sand and oil is easiest with a muller. It is an industrial version of mom's kitchen-aid mixer. It can and is done often with a shovel and something like a mud pan (like those used for mixing mortar). If you want to do it that way, buy a new pan. chipped off mortar in you sand isn't very desirable.

Thanks for that info, Chris.  Were you casting sculpture with this process?

Sorry for taking so long to reply -

The casting I have been doing is not so much art/sculpture type of work as it is small scale industrial sand casting.
Using brass, bronze or aluminum our castings (in bronze) might weigh as much as 20-30 pounds. In aluminum, 15-16 pounds.
The size of a casting, because of it's wide variety of potential shapes is based on weight. This is also the way(at least in smaller pours) that the crucible is sized. The furnace that I have can hold a #16 crucible which is, if memory serves, capable of holding 16 pounds of aluminum.

If two furnaces are available then two crucibles can be poured into a mold at the same time, doubling the size of the product.

A little more than you asked for, but appreciate the question Old Coot - makes me want to get out and do some more pouring (casting)

-Chris
