I think I'm in the wrong place. Can someone point me in the right direction?
When casting in sand with copper or aluminum how do I chose a crucible? I can figure out what size I need but what about the composition? What is the difference between cheap and expensive crucibles? What is the difference between the first three clay graphite ones (links are below)? I see a difference in the shapes but i do not know what that translates into. And finally what is the difference between the first three clay graphite crucibles and the last one a Silicon Carbide crucible. Will there be a noticeable difference or advantage between the clay graphite and the Silicon Carbide?
On one hand I want to buy the cheapest one but I also understand " you get what you pay for"
The crucible will be used in either a charcoal or gas furnace that I will build in the next 2 weeks or so.
Thank you for your reply,
