I usually make my own frit, unless I need large quantities. I've always used a coffee grinder and sifters and it just works great! I have to have my glass and supplies shipped to me, so with the weight of frit, it's much more economical for me to make my own from scrap.
I wear a surgical mask when I grind (very dusty). My teenage niece and nephew want to give me a hand this summer and do some grinding (YEAH!), but I'm not sure how safe it really is for them...If I have them wear a mask, do you think they'd be okay?

Ahh! Just saw this old post!
Guess I should have looked a little more before I posted question! Love this board! So, so much information!!

Oi smallbits!
There's heaps of stuff the glass studio that your do not want in your lungs! Surgical masks will not protect you from these things (they protect from the spatter of large droplets, that' about it). I would recommend investing in your future by purchasing and maintaining a P100 particulate filter mask for studio use.
My $0.02.

Re: Frit Dust
Oy- overkill. P95 will cover the nuisance dusts from powders.
Re: Frit Dust
My Mistake!! I have always called it a 'surgical mask'. It's a particulate mask - a P100 to be exact. I use it to scrape kiln wash and to do all the nasty, dusty things in my studio. I HAVE been using it to grind and sort my frit. I was just surprised to see this post that calls glass dust 'nuisance dust' and not really harmful. Probably don't need a P100. You certainly need to cover your face, as the dust is pretty bad, but I thought this post from Greg Rawls was very interesting.

P95 oil-proof - 95% efficient for particles ≥0.3 microns (µm)
P100 oil-proof - 99.7% efficient for particles ≥0.3 microns (µm)
As you can see, there is not much difference between P95 and P100. P100's are mainly for asbestos. The downside is breathing resistance is much higher in a P100, making you more likely not to wear it.
Remember - you can't get silicosis from ground glass. It is a SILICATE, not a SILICA.
