Geoscientist’s Toolkit: Gas-fired Tilt Furnace

When you need to make something really hot—1350 °C—a tilt furnace can be a great tool. This is especially true if you are an experimental volcanologist. At Syracuse University, faculty in the geoscience and art departments have teamed up to make actual lava flows on a small scale.

One of the major risks in studying volcanoes is that it can be hard to stay safe while studying them up close. This gets particularly true if there are interactions between the lava and snow or ice, which can cause flooding, explosions from rapid vaporization, and other unpleasant things.

However, by using a tilt furnace, small batches of rocks (basalt) can be remelted and poured under controlled circumstances. This allows studying what happens when lava flows over an ice sheet (video above), or even what happens underwater when lava comes up from the seafloor (video below), where structures called pillows are formed. Small-scale experiments like these can help scientists understand what determines which shapes the lava will take on under which conditions (slope, effusion rate, temperature).
