Looking for some suggestions on making molding sand for aluminum. I sifted some silica sand from Home Depot and mixed dry with 10 to 15 % Ball Clay I had leftover from the kiln but does not seems to have enough bonding.
Any one that have had a simple as possible mix and ratios.
Any suggestions?
Thanks
