TIL the hard way that melamine burns way faster than I ever thought

Last Tuesday I was trimming a shelf on the table saw, the blade grabbed a strip of melamine and it stalled, next thing I know smoke is pouring out and the edge is literally charred black. I killed the saw, grabbed the fire extinguisher, but the smell hung in the shop for two days. Turns out the blade was dull because I'd been cutting plywood all morning with the same 40 tooth blade, I should have swapped it out after 20 cuts, not 60. The customer still wanted the shelf, so I spent an hour re-cutting the panel and losing about $18 in material. Now I keep a separate blade just for melamine and I check the tip temperature before every pass. Has anyone else cooked a board on the saw like that, or am I the only one who learned this the fiery way?

Thought I was being clever using the same blade for everything, but this makes total sense now. I never even thought about heat building up like that, so thanks for the heads up.

Clever until your blade starts smoking mid-cut and you're standing there trying to figure out if the wood or the metal is on fire. Happened to me once with a dull utility knife, thought I was saving time and money, ended up burning my fingers through the handle. That's the kind of lesson you only learn the hard way, right after you cuss yourself out for being cheap. Now I've got a drawer full of blades labeled for different jobs like some kind of weirdo, and honestly it's the only thing keeping my workshop from turning into a hazard zone. You'll be swapping blades like a pro in no time, just don't get too attached to any one edge.
