That's a cool effect on the glaze, reminds me of a cantaloupe.

Your work looks great!

Neat, kinda looks like sourdough

Amazing work

Some boards work fine without anything except a potentiometer connected, so if I had gotten lucky with one of those, I could've avoided buying another.

I got the treadmill for 100, but you could probably find one cheaper or even free
Control board was 45+ shipping on eBay
Pot+switches+fuses+knob was around 20
Box was also 20
So <$200 so far, definitely could've cut that in half if I was more patient with getting a treadmill.

Nice! I like to use a blowtorch to dry the sodium silicate faster.

Brent is selling 10 amp glass fuses for $20.

We sell a pack of 60 fuses for 8 bucks at my job.

So, first point I want to make is to buy as little manufacturer parts as possible.
