Furnace Re-insulated

A naked furnace frame wouldn’t run very efficiently, so time for some fluffy 2600F-rated spun alumina (industrial sapphire) blanket.

We used a scrap of copper for a form and added a 1" layer of blanket around it.

Looking nice and cozy already with more insulation to come!

A soft floppy blanket won't do as a frame to hold our SiC elements (coming soon) so we soaked the alumina blanket in colloidal silica to rigidize it (once it is dry)

We made sure the blanket was soaked good. The orange tape was a temporary form to keep the blanket from sagging under its wet weight.

After not long it was stiff enough to remove the tape, though still quite colloidal-logged.

Wrapped up! Still wet with colloidal silica but she is really starting to look like a toasty furnace. We'll probably add one one layer of blanket - its quite light and would add considerable more efficiency.
