Title: Glass thickness.
Post by: Mafort on September 12, 2020, 07:29:36 am
There’s a place near me that has small mosaic tiles of glass about 4” by 4” and it comes in beautiful colors. I’d like to learn knapping and I wanted to practice on these however they are 1/8” thick. Is that thick enough to make a good point for hunting?

I don't think I would have the skills to make a point out of 1/8" thick glass unless it was very small, too small for legal hunting that is

Would you happen to know where I could find something thicker? I’m searching the internet but I can’t find much

You can use glass bottle bottoms. Look it up on YouTube.

Have you tried looking for stained glass?

I have used glass countertops before. The stuff I have works really nice.

I saw the stained glass but all I can find is 1/8” inche thick. I have done bottoms and they turn out well I just want something that’s a tad bit more forgiving.

ask around at furniture stores they might have glass table tops that have been chipped or cracked that they'll let go for penny's. also see if your city has a re-store all kinds of stuff might turn up at them.

The 1/8" thick tiles are will yield a 3/4" wide arrowhead if you're really good. That's a 6 to 1 width to thickness ratio. Most knappers should shoot for 4 to 1 to be on the safe side.

Clear glass comes in much better sizes and quality but it gets old very quick.

The best and cheapest glass I have found is bottle bottoms from carbonized water. You can find them in various shades of green and blue.
