The Pushing Technique by Robert Morey Photos By Peter  Kenneday

The Pushing Technique
 The technique of pushing a rod of glass into a gather of clear is one I use often. This was originally shown to me by Brian Kerkvliet when I attended his Milli Madness workshop. It is used to form mushrooms, jellyfish, flower stamen, and many other things inside a clear gather of glass. I will describe the process of creating a mushroom pendant to illustrate the technique, as that is the way it was first shown to me.

About Robert Morey

Robert Morey
I have been flameworking glass for six years. The only formal training I have had has been a workshop with Brian Kerkvliet (Milli Madness). I have surfed the internet, read books, and learned from every person I have worked with or near. For the most part I have experimented much, failed often, persevered through my problems, and adapted some techniques to make them work for me. The alchemy of working glass in the flame will always keep my interest.

 The Prep Work

  The prep work consists of pulling three canes, a simple milli, a twisted cane, and a striped cane. The milli is made by gathering three colors, one over the next. Keep the glass being gathered over relatively cool so the colors don't mix. Then impress a score into the gather (I use a butter knife or file, an optic mold is the easiest way). Then fill in the score mark. I usually use a dark transparent that I have pulled into stringers to do this. Repeat as many times as needed. Try to keep the scores fairly deep and even. Then thinly case the whole gather with the same transparent. Using a marver heat and shape the gather into a football shape. Attach a handle so you have a sturdy handle on each side. Heat the football concentrating most of the heat in the center part, which is thickest. When it is evenly hot to an orange yellow hue, and is pliable. Remove the gather from the torch, wait for a second or two to let a skin form, then pull it down to 2 to 3mm. This type of milli can be purchased from most glass suppliers.

  Make the twisted cane by striping different colors on a 10mm clear (in this case greens). Then clear is striped on, between and over the colors. As with the milli cane a football shape is formed, handle attached, the gather heated, but as you pull this cane the ends are twisted in opposing directions to make the twist. If you find yourself loosing control of the gather when you try to pull it heat it a little less or let it cool more before you pull. This requires developing a feel and ability to read heat base.

   Make the striped cane by clear coating a gather of opaque glass and pulling it to a 2mm stringer. Make a gather of a contrasting color and stripe it with the stringer. This gather is formed and pulled as the other canes. Pull it to a diameter of 2 to 3mm.

The Technique

  Start the technique by attaching a milli chip to the end of the striped cane. I preheat the milli chip on a hot plate.  I use tweezers to pick up the milli. Then in a sharp, small, neutral flame the chip and the cane are heated and joined together. (Fig.1) Heat is gently applied to the tip until it fuses to the cane and forms a ball. (Fig.2) The flame is then turned up to a larger neutral flame. A gather is formed on the end of a 10mm rod. The gather is formed into a tear drop shape either with marver or by heating and allowing to droop. The tip of the cane with the milli on the end has to be flashed in the flame occasionally to prevent shocking

   Allow the gather on the 10mm to chill momentarily then heat the bottom third. Just as the tip of the gather approaches white-hot and becomes runny, heat the tip of the milli cane to orange, remove it from the flame. As the milli cane passes from orange to dark red, remove the 10mm gather from the flame. Hold the 10mm rod with the gather pointing down. Push the tip of the milli cane into the gather to a depth of about 1/4 inch. (Fig.3) Wait for a moment to let the glass flow around the cane and eliminate air bubbles. Then push the cane into the gather. As it hits the cooler upper section of the gather it will roll outward, forming a mushroom. Pull down slightly at the end of the push. (Fig.4)

  Let it cool just enough to stiffen then flame off the striped cane. Pick up the twisted cane and heat and wrap it around the bottom off the bead. Twist the twisted cane as you apply it so as to twist it tighter. Take a 4 or 5mm clear and heat and wrap it around the bead at the bottom to even out the shape. (Fig.5) As you are doing all these things you have to take time to reheat the 10mm handle were it joins the tear drop gather. This point wants to shock and crack. If it does crack, and it often does, attach a punty to the bottom of the bead and fuse it back together in the flame.

  At this point I pick the side that looks best. On the opposite side the bead is heated and then laid down in some aventurine frit. The frit is melted in and a background color is added. (Fig.6) The bead is then flattened slightly (not so much as to crush the mushroom) and formed into a pleasing shape. A punty is attached to the bottom of the bead. The top of the bead is heated, removed from the flame, and pulled down to 5 to 6mm. (Fig.7) I let this cool until it is stiff, then flame it off leaving a 1/2 to 3/4 inch thin section to bend into a hook. A pair of round needle nose jewelry pliers is used to bend the heated section and touch it to the back of the bead then tugged straight. (Fig.8) The pliers are removed and the touch point is heated to fuse it to the back. As the hook is allowed to cool for a few seconds heat the pliers in the torch. When the hook is stiff grab it with the pliers and snap off the punty. Flame the punty mark smooth in the torch.

(Fig.9) When the bead is cool enough not on take on shelf marks put it in the annealer.

Jellyfish

  The jellyfish bead is only a little more difficult to make. We will cover having multiple occurrences of the pushing technique in the same piece so we can have more then one jellyfish in a bead. The jellyfish has two parts, the mantle that is formed by creating a milli, and the tentacles, that are made of a multilayer striped cane.

  The milli for the mantle is something I still play around with. There are so many different types of jellyfish. A store bought milli can be used but I will describe my latest experiments so you can give them a try if you like. Alabastros have a nice translucent quality to them. They are also prone to thermal shock and must be preheated in the kiln to a temp of 1000degF or they pop off the rod. Get a gather of white opaque and case it thinly with red, pink, or coral. Case over that with white. Pull this out so you have 6" of cane about 3/8 in diameter. Set this aside in the kiln with a handle out so you cane retrieve it. Get a gather of white alabostro going and transfer it to a 10mm handle. Gather clear over it so the thickness of the clear is the same as the diameter of the gather of alabastro. This should end up being about 3/4" in diameter. The cane made previously is removed from the kiln. One side of each cane is heated and are lightly pressed together. The smaller cane is nipped off even with the end of the gather with a pair of end nipper pliers. Clear is striped on each side of the applied cane. The same is done on the opposite side. This is repeated so that four equally spaced additions are made. Clear is striped into the valleys to fill out the cylinder. This is marvered out and evened up. A stripe of alabastro white is applied over the center of the valleys. Clear is gathered over this then a layer of white opaque. Scores are impressed into this and filled with transparent light turquoise. Finally a thin layer of transparent light turquoise all over. Pull this down to 3 to 4mm.

  The cane for the tentacles is started by first making two filigree. A gather of white is cased over thickly with clear and pulled down to 3mm. The same is done with a gather of alabastro white. A gather of light pink is rolled through gold adventurine and cased over with gold pink (rubino oro) and pulled down to 4mm. A gather of clear is started, the pink cane is striped on 4 side and clear is striped over it to encase it. The filigree are laid on alternating with each other all the way around the gather. They are applied by heating a strip on the gather and one side of the filigree, then laid on gentle and snapped off at the end of the gather with end nippers. These are applied this way to keep them round so they look more like tentacles. Fill this out with clear to form a cylinder. Pull it out to 3 to 4mm.

  The jellyfish are made in much the same way as a mushroom. Place a dot of opaque white on the end of the tenticle cane. A piece of mantle milli is joined to the tentacle cane and pushed. At the end of the push the striped cane is snapped off with end nipper pliers. Clear must be gathered over the end of the bead so that the fish float. When the first jellyfish is completed a handle is attached to the bottom and the original handle flamed off. This is set aside in a 1000degF kiln to keep it from shocking. Another jellyfish is made the first is retrieved from the kiln and the two joined together. This is heated and shaped, the bottom handle removed. A sea floor is added to the bottom by inserting a gold, green, or blue piece of adventurine. Millis are added to simulate other sea life. Some green twisties are applied to the back. A piece of blue dicro is added to the back and cobalt blue transparent applied over it. These are all techniques I learned from the Patti Walton Aquarium video. The bead is then shaped, hooked, and put in the annealer.
