All the molds are made except for the final stage of the hollow core cast bubble on the end of the blow pipe. I have been putting in endless hours to test color for the piece. I will need to make clear, blue, a pale yellow, gray and several brown tones, I mix my base batch, and test colorants in 2 lb melts. Every test batch gets mixed for 1 Hour, put into a small crucuble, pot and taken to 2000 degrees. It then gets poured out and anneled. Once I see how it looks as a transparent color, I bring it back up in temperature and hold it so that the color will opacify. This then gets annealed. This lets me see the same test in an opaque tone.
There were 26 molds in total. After the wax scene was completely recreated and finished, I cut everything apart (as can be seen in proir posts). I made each piece a seperate part (mold) that will be joined together later. The mold in this post is for the bubble of glass on the end of the blow pipe. It will be a hollow core cast mold. Below illustrates what I intend to make in an red-orange colored glass. I made a model of wax, then made a rubber mold of that. From the rubber mold I poured a silic-plaster piece. Following this post (when all the other molds are out of the kiln-Not shown yet) I will dip the plaster silica positive in wax and then create another mold from that to which I will cast the orangish glass into. This will be posted later on.
eWorking on the bench seat, rails and work table. The wax need to be invested in mold material and then steamed out. The molds then need to be cleaned and measured for the amount of glass needed to fill the void.
