Edge chipper

[Swampy]

Anyone ever use this tool?

How did you set up the cutter?

I used it here on 20mm float, set the vertical and lateral depth to 18mm but it looks like it takes too big a chomp at a time. The tinted piece is 10mm float.

I fired them afterwards to round off the sharp edges but I'm thinking there must be a way to set the cutter differently?

Just wondered, like how some of you guys fuse stuff in your kiln too...

TIA

I get the same effect by nibbling with some groziers pliers. Kind of an irritating pain in the ass really unless you're going for that look, but sometimes you do what you gotta do.

what is that cutter called? effect looks like some advanced flint knapping

Au contraire mon ami, il est très populaire, vogue!

An edge chipper.

i'm not sure how well it will work on just an edge, but aless-predictible way to get that effect is an old sign makers technique called 'glue chipping.' basically you paint a hide glue (usually rabbit) on a flat surface, and as it dries, it shrinks ripping up clamshells of glass as it goes. it looks really nice and a lot more natural than the mechanical edges you get from a tool. i've done it a couple of times on flat glass now with ok results and once on a round vessel with a very 'meh' outcome. the depth and size of the chip and the evenness of the pattern are a function of the thickness and evenness of the glue and the time it takes to dry. humidity and temp are a factor. again i haven't done it much, but i'd be happy to answer any questions that i can.

EDIT: Glue chipped window glass

I recall seeing some Hamm tubes with marias in them that had those same kinda edges but not flame polished(very sharp) maybe Mer can chime in one this one

Thanks very much for chiming in, I'm familiar with that process, I used it as a decorative effect in a lot for door fanlights when I used to do signwork. Gilded the back of the glass, it looks very nice from the front of the house. I was always inspired by Mike Jackson's work and tried to apply that to glue chipping.

What I'm trying to do here is make kind of iceberg chunks of glass suitable for engraving for trophies, I like the effect on the edge but having to firepolish the edge in the kiln to make it safe takes time.

Thanks again.
