Default Glass dust

How big of a concern is glass dust exactly? When cutting murrini or glass rods should a mask be worn at all times? What about dust that accumulates on surfaces from making or using frit or cutting glass?

I never thought of cutting murrini.
Yesterday I made some glass frit, and I put a little water in the tube. The problem came with getting it out, as it wanted to stick to the sides of the pipe instead of flow out with the water I poured it into a paper towel to let dry (on the patio) but I'm thinking I will try a coffee filter next time just to compare.

It is a concern. Repeated exposure over time can cause a cancer like lung illness called silicosis. Some dust is created whenever you cut or break glass. I do not wear a mask to do that but I try to keep it isolated to my bench which is well ventilated by a hood.

Ok, I make murrini and always wear a really good mask to cut it but I cut a lot of glass and murrini on the fly at my bench and am starting to become really worried about it. I'm not sure if that amount is ok or if I should change my work habits. Over time I notice a lot of tiny chips or dust begin to accumulate on my table.

As an occasional thing, it's not that big of a deal, especially if you have your ventilation running and don't have your face all up in the flying dust. If you do it often, I would suggest putting your mask around your neck or on your head so that you just have to pull it up/down.

Yes. Good stuff here. I think you have to weigh the risks versus what you are willing to do to avoid it. Like shawnette said occasionally at your bench and I wouldnt bother with a mask. If your gonna spend an extended amount of time cutting then a mask is a good idea. Its a judgement call.

Tom Holland has a really educational video clip of glass dust flying while cutting long rods or murrini. He recommends cutting them under water if you're going to be doing a lot of it. Confines all the dust in the first place.

Cut everything underwater if possible, you can rig a cutting tub up easily with a wash tub and a recirculating fountain pump with a filter. Every glass dust particle you ever breathed in, IS STILL IN YOUR LUNGS. Unless you may have hacked it up, but still, it doesn't break down ever in our lungs and just builds up. Its kinda like black lung disease with coal miners.

I cut my small murrini in a zip lock bag- hands, cutters and murrini cane in the bag. Helps with the dust and murrini containment.
Larger murrini with a wet saw

I do mine under my vent.

If you do them underwater, though, you have the benefit of knowing where the pieces are in addition to containing the dust

If you cut under water, do you dry & oil the cutter afterward? I'm wondering how to keep rust away.

You don't actually have to submerge and cut. You can just wet the cane and it cuts down the dust, also. I've been known to use spit. (I know. TMI, lol!)

I have a glass saw that is always wet. Mostly I just nip and cut under the vent though.

The kiln sterilizes things, yes, that's it.
