This short pour of 200lbs of lava was heated/fueled by coke, compressed air, and a little oxygen. This is a major development toward the goal of creating a geomorphologically accurate lava field. By switching from the gas-fired to coke-fired furnaces the cost of the project as a whole dropped 60%, now its feasible and I've solved the problem of the intermittent pours from the gas-fired furnace. By using the coke-fired furnace to produce lava, a continuous flow of lava is created; only ceasing if not recharged. It's a volcano or at least a volcanic vent. The coke-fired furnaces I've started to build will accommodate greater lava/basalt/coke loads, by a factor of 4. Stay tuned, I'll have a working model of a very large furnace (3 tons+ of lava an hour) up and running by November. As always thanks for taking time to look at the progress.

Hmm…it looks like things are taking a while to load. Try again?
