I am new to hand pouring and I have just started pouring my own Senkos. I purchased a mold from Del as well as my plastic (Calhouns). I have poured a few stix now but I am having a real hard time with small pockets at the end of them. If I work at it really hard I can finally get some good pours but I'm not sure what I'm doing wrong. Am I not shaking my plastic enough?, Am I stirring it too much/not enough as I'm heating it?, Am I pouring to fast?. I get my best pours when I pour extremely slow but I'm just wondering if there is something else I am doing wrong. Any tips would be greatly appreciated.
