I tried again Leslie, but didn't fare so well last night.
The "point" on the left I had high hopes for. There is a little crystal inclusion you can see that I thought would be very cool in the center of the point. Unfortunately, it acted like concrete and wouldn't let flakes run through it on the other side, where I had coretex.
It also had a spot on one side where it wanted to crack so I was a little tentative whacking it there. Of course, that resulted in steps and I finally gave up on it. I'll toss it in the pile of goofs and 3 months from now I'll have learned enough to go finish it.
The white point is white glass. It should have been twice that size, in fact I was planning on a knife blade from it and consequently wasn't trying to get it particularly thin. I don't know if it had a flaw or if I just mishit but in 2 whacks I took half the width and a third of the length off the preform. In the end I had trouble thinning the point and even as small as it is it weighs 175gr.
Not my best night. Probably didn't help that it was 105 in the shop. The pool went from 81 to 88 degrees in 1 day. It's beginning to feel like bathwater already. Looks like a hot summer this year.
