Make the cone out of clay. Leave a hole for the good stuff. Buy saltpeter from the drug store (no prescription needed). Mix half and half with sugar. To be acentic sprinkle in some sulfer for smell. Now lite it. This mix won't explode but makes for a good display. [To make black powder requires charco in the mix.]
Alternate method mix iodine (the more the better) into the clay. Insert dry ice into the hole, now pretend it is raining and sprinkle on a litle moonshine or wood alcohol. Have flint ready.

What you need to do is to take a high temperature oven and melt some rocks. Then you need to devise a system that will push this liquid upward where it can collect in a cone shaped manner. Good luck in figuring out the details. By the way, I know of no volcanoes that use vinegar and baking soda to form cones.

Baking soda + Lemon Juice or other acid like vinegar. will produce the fizz you want. Make the base out of anything fairly water resistant.
