I use only 50/50 #1 pottery plaster and 200 or 300 mesh silica (depends whIch plaster your local supplier carries) Seattle Pottery has 200 mesh silco-sil. I use talc as an inner core and find the above recipe with fiberglass shorts easy to get of off a thin walled vessel. The heavy high temperature ...

[/quote] "Jerry" According to Thwaites the ludo may cut down on cracking because a) the ludo has various sized particles and helps with packing and b) chunks of ludo act as aggregate to stop cracks running through the mold. Also ludo is classified as a refractory or a modifier rather than ...

Delores I was under the impression that the ideal mix has 40% plaster by weight and that doing it by volume, more or less approximates that figure. I think the idea is to have just enough plaster to get it to set up hard enough to work. When I make up recipes by weight, I leave the plaster at 40% a...

Hi Delores I received today a new package of plaster and silica. You may disbelieve, but I can´t buy silica here in Rio de janeiro, I have to buy it in São Paulo -thank God for the net... Tomorow I´ll throw off all the old stuff and try all over again. What do you think will happens with the pla...

[quote="Delores Being more explicit about your mix being a mess might help us figure out why. Best wishes in your castings it can be very frustrating but it's really worth all the efforts. Hi Delores What is happening is that the mix seems a thick mud , and it never dries.. Today, as I read at...

hi! i am new to the warm glass forum and basically to the realm of warm glass altogether. i know the basic idea surrounding pate de verre casting,. but am wondering about a program using bullseye fine frit in clear to cast an object (more specifically, the two halves of a clam shell) that will be a...

Hi I´m trying to make a plaster/silica mold, but it seems impossible :?: I´ve made the mix of plaster and silica by weight. Mixed very well... Then I tried to add it to 1 liter of water - result was a heavy and very very thick mess... I tried 1,5 litres and 1,75 litres the result of both was a me...

Has anyone tried layering up carved out fiber board, pinning the layers in place and frit or potmelt casting into the board? I'm looking at molds 6 to 8" deep - or deeper. I'm getting ready to do some R&D with this idea - any pointers would be welcome. Thanks. Hi Gale sounds like a fun pro...

The books I have studied say to bring up the temp of the mold slowly to around 1200 degrees, cool, and then fill the mold with frit. I understand curing the mold, the need to remove chemically bonded water, and the need to go slow. I use holds at 250, 350 and 1000 (physical water, chemically bound ...

Gale sez... I hope present company is excepted from this statement - LOL! Present company always excepted! In fact I had the good fortune to finally meet Deloras, Catharine, and Els during our vacation. Woe to me that they live so far away. Had a great time grrls. e I'm sure your family would love ...

Because I find life a source of joy, sorrow and inspiration and it’s a way for me to express these emotions. I know this may be an ignorant question, but when you are sad, does your glass look different than when you are happy? Are you successful in conveying these emotions to the observer? Tony ...

Hoping to get a discussion going: I'm a voyeur at heart and am very interested in our (quite/most? often misguided) perceptions of others which are, of course, based upon our personal life experiences. This is where my work starts, why I choose the subjects I do... Catharine[/quote] 1. Why are you d...

Wonderful work

It was great to see you last weekend.

I think GAS was wonderful and would highly recommend it to anyone. Brad being such a strong presence for kiln formed art is an important venue also. We do not need less we need MORE if change is to truely take place. These type of venues are so very powerful, they provide a place for artists to see ...

I'll be shipping a large glass piece (87 seoarate sheets of painted glass up to 4 ft. long) to Europe and started phoning around locally (Boston) to find out how to insure its replacement value, which is about $10K. Have been told, We don't do that, We won't do that, Get it professionally appraised...

This is my understanding of the differences ... CV --includes work history, teaching/lectures, educational information Bio --is a chronical of what you've done in full artist statement --tells what your work is about and reason you did the art artist resume ---is highlights of education, the shows/e...

What a treat to get the latest AC and see the beautiful article on Dan and Lani's house. The artwork and house is so lovely and shows how elegant and integrated the two are in Dan and Lani's life. Of course the cats nabbed the lime light by getting into the photo op. Yo, Lani do those two have their...

First look at your work and do a quick list of the features and highlights of why you creat what you do. An artist statement is what you want to say to others about why you work in your medium (inspirations) and what you are trying to say (what you want others to know about you). There are business ...

you wrote: GrainSize/BubbleSize/BubbleDensity/Translucency Cullet/ large/ thin/ transparent Frit (mesh size JIS 60)/ small/ small/ translucent Powder/ minute/ dense/ opaque this information is great, and appreciated, BUT, is there anyway to get those tiny bubbles outta there, to make it a bit close...

Congratulations to Catharine Newell, Ellen and Marc Levy for getting accepted into 'CraftHouston 2003: National'. What an honor. If I've missed any other warm board folks who were accepted also a hearty congratulations and job well done!!
