Did my first casting about 35 years ago. Have most of a container of Marvelux left. Memory seems to be that it worked well. At that time I used a pot and dipper. Went through about 3 gallons of wheel weights, using a 214 gr. Lee 44 and a 150 gr. lee 30 mold. Have recently acquired a few more molds and some wheel weights. About a month ago I smelted about 62 pounds of WW and 24 pounds of Came lead. 2 days ago I smelted another 125 lbs of WW. On these last two smelts I used motor oil and wood shavings for flux. On the last batch I also picked up a Red Cedar limb to stir the pot. Got good clean ingots with little dross loss.
