Re: powders-good studio practice-avoiding contamination
Hi Cynthia Many thanks for replying, your answers are always so interesting. Also for the pictures. The idea of making little compartments on the base glass by gluing strips is great, I'll put that into action. Also about marking a corner. Made a plate with 36 colors, and a matching diagram on the c...

powders-good studio practice-avoiding contamination
Hi, Have just started working more intensively with powders. My question relates to good studio practices to prevent cross contamination of colors and to keep the area clean. (use a proper respirator and a big white cotton shirt over my warm clothes). Because I am just starting, I am preparing small...

Re: drop vase - strips separating when making blank
I don't have a lot of experience on this, but I'm thinking you'll have a difficult time dropping three layers 10". My guess would be that you'll stretch the blank so thin you'll get holes. I seem to remember a heuristic that says you can drop 1" for the first 2 layers, and then an additio...

Re: drop vase - strips separating when making blank
Hi Ed many thanks for your detailed reply. I am starting to understand the factors that come into play with the different viscosities. Also to see what a full fuse is...I should probably have posted this query in the newcomers section, working this thick is a new experience for me. Then I have never...

Re: drop vase - strips separating when making blank
My uneducated guess is that your strips were opaque. many opaque glasses are more viscose that clear glass. During the drop gravity pulls the glass gown. The softer Tekta gives more and this may cause full separation of the stiffer strips, leaving a clear line between. There may be a difference -- ...

drop vase - strips separating when making blank
Hi Have just made my very first drop vase, ½” thick blank, dropped 6” I am happy with the results of the drop. However, I need to improve the blank. The blank layout was 2x 1/8” Tekta base, ring mold size 2 layers of colored and tekta strips on top of this base. These are shorter than the width of t...

Re: Choosing flat lap disks - type and grit
I'll amend my previous post to add that the bowls we were working with had been dropped through a Ceramaguard (sp?) board and the "flaps" had been sawn off. The resulting bowl edges were already semi-flat, semi-smooth, and semi-parallel before we started hand grinding. (Please - no math m...

Re: Choosing flat lap disks - type and grit
The angle depends on the mold I'm using--I have a contour gauge that I set at right angles to the table, take a profile off a bowl made in that mold. Then I run a tangent off the profile and figure out where 90 degrees parallel to the blank and 90 degrees parallel to the table would be. The differe...

Re: Choosing flat lap disks - type and grit
Many thanks Morganica and David, that commercial is almost convincing :) The part I never quite understand is if this works for the polishing end of the work, let's say from 400 grit upwards, or if it is also "quick, effective, and easy" at the beginning of the grinding, the 'shaping stage...

Re: Choosing flat lap disks - type and grit
I've been getting excellent results using grit. I have a rociprolap that I use to grind down the edge. I am usually super aggressive (with chipping) at 30 or 60 grit then I move to 220 - 320 and then finish with 600. I use a pad and cerium oxide to polish. Both machines are 24" diameter. The m...

Choosing flat lap disks - type and grit
Hi, Could I please have your help with choosing some flat lap disks? 16", no hole, magnetic backing. Using a converted pottery wheel. Main use will be grinding the edges of some 3 to 9 mm ( 1/8” to 3/8”) thick bowls. Horizontally, parallel to the base. Would like to achieve a “gallery quality” ...

Re: CNC glass scoring from Thomas Carr
So how much glass can a good cutter cut if a good cutter can cut glass? Before you go spending money on a fancy cutter, think of all the glass you are going to have to handle just to pay for it and then sell to currently non existent customers. I know, I know. We just like machines, and if it could...

Well I actually ordered it. Twice. Never received it. Went to see one in New Orleans. It didn't. meet by needs. That one was returned. I don't know if he is still in business. Like I said, I bought a wood cutting CNC and built a glass scoring head attachment for it. Works very well. A little pricey...

Thank you Tom and Lauri. Have checked the tools you suggested. From the shape, the only one that 'looks' similar is the Glasstar. I suppose in principle all work in a similar way.
