    I just read the tread on "raw lead prices". The shooting industry is in for more hard times. This time from "within".

    This is just a thought. Has anyone ever tried manufacturing GLASS SHOT.
    I believe glass can be made hard (bullet proof glass)and heavy (lead crystal).
    Maybe someone can develop glass shot to use in target guns as an alternative.
    It may not be as good as lead, but it may be better than steel and a whole lot
    cheaper. There's alot of sand out there! What's your thoughts? Thanks.

    I think it would work if we also went to using steel targets,,, that way we could reuse the targets, and the scorers would just count the dust balls made from the glass shot hitting the steel targets. LOL What an idea I think that I will Patent it.... and we will color the shot Black ...

    Clay targets! How about "Slate targets"? Up here in Vermont and Eastern NY. The slate slag is everywhere. Millions and millions of tons of it. No current uses. How about grinding it up into a powdered form adding an adhesive solution and pouring into clay target molds. No pitch, completely non toxic and instantly bio-degradeable. I think this would work. What's your thoughts?

    It won't take long for the glass to ruin your barrel as it is very abrasive.

    Is glass more abrasive than tungsten or steel(itself)?

    Glass will dull tungsten carbide very easily.

    Hey we could to that "Slate targets" with Mt. St. Helens ash too as ASH Targets. There's unlimited supply there. Now back to the shot problem.....

    There are companies that make glass beads that go into light reflective paint. The beads are made in a similar fashion as lead shot. One company was 'Cataphote' in Mississippi but I think they are out of business. There have to be others to supply to the paint industry.

    The bulk density is probably too light for target breaking efficiency and the abrasive factor must be very high.

    Hey, If the slate has been in the ground for a bejilloin years how is it biodegradeable? Maybe you mean't "Environmentaly Friendly"?

    Just found out that Cataphote is alive and well making spherical glass beads for the traffic paint industry in Jackson, MS.

    Glass is mostly silicone dioxide. Even leaded crystal is only a 35% lead.

    Not a very dense material. Not even as dense as steel.

    Mom's nice leaded crystal vase would weigh a LOT more if it was solid lead.

    Silicone dioxide (glass) is about 2.2 grams per cubic centimeter.

    Lead is 11.34 grams per cubic centimeter.

    35% leaded crystal would be about 5.4 grams per cubic centimeter.

    Probably not a good chice for a shot material. Even if it made it all the way out the barrel without turning to powder.

    grams per cubic centimeter is the density unit you are thinking of.

    DUHHHH

    What am I thinking? I'm a freaking professional engineer!

    Hope they don't pull my license!

    I fixed it in the post.

    Awesome. Another PE on the forum. What discipline? I'm Mechanical. Power Plants.

    Where'd you get your post name?

    Why not a gaint tarp sloped to a funnel that reclaims all shot.

    I going to sit for my FE in mechanical this month. Glass is several times less dense then lead, or even steel. I personaly don't believe it has enough mass to travel 30+ yards straight. Even if you could get a halfway decent pattern you would have to have a very high velocity to get the necessary engerty to break a target. -Rich

    On another note, any test taking advice?

    richrob,

    Umm, back when I took my FE exam in 1983 it was called the EIT (Engineer-in-Training) exam.

    Not even sure I can remember what was on my 1989 PE exam.

    My only advice for you is what is on the front cover of the "Hitchhiker's Guide to the Galaxy."

    DON'T PANIC
