Got questions
about silica?
Good.
You should ask. So we paid an independent industrial hygienist to find the answer.
Silica is serious. We're not here to tell you it isn't. We're here to show you what's actually in the air when you charge a furnace with Glasma.
The fear around batch is real, and most of it is built on the powdered batch the industry has used for decades. The kind that puffs into a cloud the moment you open the bag. That reputation followed batch everywhere, including to products that behave nothing like it. So instead of asking you to take our word, we measured it.
It's not a powder.
It's a pellet.
Dust exposure starts with whether the material can become airborne in the first place. This is the whole ballgame, and you can see it without a lab.
Like a bag of flour
Fine powder. Open the bag and a portion of it goes straight into the air you breathe. The dust is the default state.
Like a bag of kitty litter
Pelletized granules. Too heavy to float. They pour into the furnace and stay put instead of clouding the room.
The lab couldn't
even find it.
An independent hygienist monitored a full 8-hour shift while a worker charged the furnace six times, wearing the air sampler on the collar, in the breathing zone. Here's the worst-case result against the limits that exist to protect you.
We didn't grade
our own homework.
Every part of this was independent. We don't own the equipment, the lab, or the sign-off.
Straight talk.
So we're clear about what the test does and doesn't say:
- "Undetectable" means below what the lab can measure. It does not mean we're claiming zero silica forever. We're claiming the air was clean in real-world use.
- This measured furnace charging, the dustiest task. It's the right thing to test, and it's still just one task in one studio.
- Good ventilation and sensible studio practice still matter. The point is that even with normal airflow, Glasma tested clean. Keep doing the smart things you already do.
- If you're a skeptic, you should be reading the actual numbers, not our summary of them. So here's the full report.
