Creativity Demands OPTIONS

Neck & Neck
-
This set up assumes the piece will be transferred to the punty and opened to its final shape with jacks. The open end is reduced in the throat for good back pressure. Excellent for stretching lip wraps thin.
-
This set up is for open ends that need more precision, such as lamp shades with fitters or glassware with a ground lip. It's also good for controlling the thickness of the edge.
The Bases
-
Rounded Bottoms
The bottom of the form is a convex curve, captured in the shape of the mold
-
Flat Bases
The bottom of the form is flat, such as a drinking glass or a vase.
-
Fitted Bases
The bottom of the form has a concavity, such as the punt of a wine bottle. Care must be taken that the form can be released once blown.
-
Through Molds
Molds go straight through to a board or the floor. Open on both ends and for use with a base board.
-
Gridded Base
The grid gives it venting. Has a grid shape of channels for venting and used with a Through Mold.
-
Barn Doors
For large, wide forms. Allows for lenses and domed chandeliers to be made easily.
Venting
That steam needs somewhere to go. Blockhead’s Design Team works with glassblowers and designers to select just the right pathways. Finding the path and keeping the shape.
Holding It Together
-
Alignment Pins
Nifty little brass fixtures to keep your mold in line. Embrace consistency.
-
Locking Clamp
Holding the mold sides together so you don’t have to. Easy release.
-
Carrying Handles
For relocating large molds around your work space. The grips lock halfway up so as not to crush fingers.
