Cutting out the rest of the shapes Video contains all the different cuts Molten metal welded the edges slightly but when grinding the raised parts away it released the shape from the sheet. During the cutting I didn't see one of the offcuts sticking up and the sheet was shifted as the nozzle moved Shape came out well, but realised that the drop spaces come right to the edge of the dam. will test it and see if it needs to be re-cut or adapted Size of shape has meant there is
Yet another test Adaptions from the previous firing Less height again on the dam lining Longer soak at top temperature The glass placed in dam pre-firing has been cut up smaller to allow glass falling through melt plate more variation in depth Test 1 and 2 combined make the appropriate height for this piece so used them to work out an exact weight in glass. Due to quantity of glass, could probably have done with a bit longer at top temp to get rid of final spike and bubbles.
Next stage in the proofing process Cut fiberpaper lower to reduce waste Lined with kiln paper Longer soak Some clear glass put in the bottom of the dam before firing Really please with the way the glass has flowed through the melt, sides are a lot nicer. Still bubbles but much reduced since test 1 kiln paper fell on top of glass after it cooled and has left a shadow, but easily fixed. #Mountkeen #glass #tests #process #colour #wiremelt
Post disaster tweaking Got rid of pink and green design as they had the worst outcomes from previous test. created a 3 variations for each dam shape using the red, purple and black designs Plates made from 2mm stainless steel Had to lower the speed of the cutter from recommended as it didn't cut through cleanly . after cutting the shape out, plates needs ground down with an angle grinder, just to remove any burs Testing with this plate first to make sure any bend in the metal
Taking wire melt shapes from drawing sketchbook to initial testing Shapes taken from charcoal drawings, rearranged and simplified Preferred shapes chosen out of all the developments mild steel test plate created to check sizing and see approximate material loss during cut. Liked the sizing in comparison to the cardboard size plates so made one from 5 of the variation groups. Shapes chosen as most intricate from each variation- if these work, the others will work. Shapes cut i
Small test piece to see if what I'm planning will work Glass has been melted in a mould using thin fibre paper to shield the glass from the metal mould. The colours used are a rough representation of some of the colours that may feature in the final pieces. Fibre paper was also laid under the piece of glass during firing to pick up subtle shapes (in this case slight corners) to see the effect. A rim of copper has been made using acid etching to reflect the striations of the r
