Many thanks to everyone for your advice on this. Brock was right about the site - although they didn't give much 'how to' information - I went ahead anyway and cast a smallish open mold which I sprayed with kiln wash and then filled will smashed up spectrum 96 melted from a suspended flower-pot. It ...

I am making a shape out of three layers of fibe board over which I will slump a blank made up of two thicknesses of spectrum 96 already fused together. I had already made two layers and decided to add a third layer to give more depth. I cut out the shape from one eighth board, laid it on top of a sq...

Just moved to casting from slumping and have been given a big bag of a this mold making material but can't find any information about it. It is a French product which may be known under a different name in UK or USA. Does anybody know anything about it??

Best wishes

Having been inspired by all the high fire and pot melt posts recently I have made some quite interesting pieces, however cutting them into circles seems to be a tricky. The one I cut today was 3/8th inches in thickness with a diameter of 16 inches. I used the little circle cutter device which came a...

Cynthia - I really liked your example of the mica powder powder on amber transparent capped with clear. How did you do it? Did you airbrush the mica or just sprinkle it and did you fire it before you capped it ? and at what temperature. I'd really like to give mica's a try but my first attempts seem...

I want to make a blank to use with a drop-ring (first attempt), and would like to fuse together two 12" transparent circles, with a smaller coloured circle (about 8" in diameter) sandwiched between the two larger pieces, in one firing. Glass will be Spectrum 96. The idea is to have a trans...

Hi Charlie - I'm going to try your method but would like to ask why you don't use thinfire paper to line the ring - also presumeably you use stone floor tile??

Best regards

Hi There... A mold I was preparing for slumping just broke in two pieces as it was drying in the kiln and I've no idea why - can anyone help? I had re-applied kiln wash to my shelf and dried it in the kiln to 500 and it was cooling but by no means cold. Having sanded and kiln washed the mold I put i...

I had a slight disaster so smashed the pieces, which had already been fused and slumped at usual temperatures, and put them into a pot holder and melted at 1650 to form a new piece of swirly coloured glass which has been shaped and sandblasted with a view to slumping into a bowl - so my questions ar...

I got my Efotobolle powder from a supplier called Creative Glass and you can find them on http://www.creative-glass.com. They have studios in the UK and Switzerland, but I'm not sure if they have a set-up in the US. I haven't done it yet but I thought I'd try mixing some baking powder and coloured g...

Hi Cathy, I think you might mean Effotobolle powder which is available in lots of colours and creates a blistered bubble effect when it is sandwiched between two sheets of glass. the supplier says it is compatible with all kinds of glass but I have only tried it with clear Spectrum 96 brought up to ...

Only very early results - I sprinkled 4 colours between 2 pieces of 3mm float glass and fired at 1400 because I was slumping another piece. The green and the blue produced some nice coloured blisters of varying sizes up to about 1cm in size, but nothing happened to the white and the yellow. I refire...

I first saw an example of what I think is this technique in Barcelona this summer and then discovered the powder in a catalogue from a Swiss Company who have just opened up in the U.K. their website is not very informative but they may be reached at http://www.creative-glass.com I will give it a go ...

Hi - has anyone any advice on how to use this. I think it is supposed to create a rather interesting coloured burst bubble effect when used between 2 sheets of transparant glass. I ordered some and have received some plastic bags filled with a very fine coloured powder - rather like paint and I'm no...

Does anyone have any tips or advice regarding gutting straight edges with this ring saw? I would like to straighten the edges of some rectangular and square pieces after fusing and before slumping. The straight edge attachment for this tool is only useful if you are cutting pieces from a 'straight' ...

I've slumped two different shapes - both in new, beautifully smooth molds which I coated with about six layers of kiln wash which I smoothed by hand before using. I slumped both at 1280 and allowed to soak for 30 minutes before bringing down to 950 and then annealing in the usual way. I'll also try ...

Hi there - I need some advice on getting a smoother finish. I have fired a tranparent base topped with white opaque and finished with coloured designs and although the finished piece looks OK on top, the base is very rough. I have just made a dinner plate and I wouldn't want to put it onto a polishe...

I am totally intrigued about the idea of slumping bottles, but what do you do with them when they are slumped? I imagine a round bottle coming out of the kiln as a sort of flat silhouette type bottle shape, is this right? I'd love to know more as I do seem to end up with a lot of empty wine bottles!...

I use Spectrum 96 glass, because that was the glass used on my fusing course, but on looking at the various forum discussions I note that most people refer to Bullseye and wonder if it is worth changing. I have spent quite a lot of money on sheets of Spectrum 96 but am curious to know why everyone e...

Hi there I have slumped a 13inch blank into a shallow dinner plate type mold and the finished piece has a huge bubbble which makes it look more like a hat than a plate! a second attempt produced exactly the same result. :( The mold looks a bit 'enclosed' ie two air holes in the centre but the edge o...
