First tests fusing glass and copper
Absolutely love the colour that the copper goes when it fuses with the glass. Really like how the glass flows over the metal forms.
Temperature test at 720 °C - some fusing round the corners but a lot of tension - my theory is that the metal is shifting after the glass has cooled I think that as the temperature increases and the fusing becomes more wide spread the tension will become less.
Temperature test at 815 °C the fusing is much more complete still some small points of tension.
Next stage of testing is to see how the copper does in casting and if the total incasing in glass eliminates the tension.
