4 sugar/6 Kno3 is what I use. You can play with the ratios, ex. 1 sugar/1 Kno3, or even use different sugars, Granular, brown, powdered. Melt the sugar, then add the Kno3 & let it dry then light for thicker smoke.
Above is salt petre (Kno3) & sulfur. These come from your common grocery/drug store. This can be your supply if your a beginner. (The sulfur can be used in exotic smoke mixes & black powder)
Do not melt both (Kno3 & sugar) together, I have learned that from experience, almost burnt my kitchen down. Had to replace lanolium. You get the picture.
