How to Make a Glass Mushroom Pendant with Lampworking
Here is a neat lampworking project you can do to sell and earn money.
In the above video you learn about the tools, materials, and technique to craft a glass mushroom pendant.
Some items talked about in the video are:
- graphite tools
- push tools
- shaping tools
- brass tools
- red rocket torch
- 25mm borosilicate glass tube
- 12mm glass rod
- color rods
The video also goes over some of the safety concerns such as working with powdered glass, and toxins that are given off when working with borosilicate glass.
“Borosilicate glass is a type of glass with the main glass-forming constituents silica and boron trioxide. Borosilicate glasses are known for having very low coefficients of thermal expansion (~3 × 10−6 /°C at 20 °C), making them resistant to thermal shock, more so than any other common glass.
Such glass is less subject to thermal stress and is commonly used for the construction of reagent bottles. Borosilicate glass is sold under such trade names as Borcam, Borosil, Suprax, Kimax, Pyrex, Endural, Schott, or Refmex. Borosilicate glass has a wide variety of uses ranging from cookware to lab equipment as well as a component of high quality products such as implantable medical devices and devices used in space exploration.
Borosilicate, or “boro” (as it is often called), is used extensively in the glassblowing process lampworking; the glassworker uses a burner torch to melt and form glass, using a variety of metal and graphite tools to shape it. Borosilicate is referred to as “hard glass” and has a higher melting point (approximately 3,000 degrees Fahrenheit / 1648 degrees Celsius) than “soft glass,” which is preferred for glassblowing by beadmakers.
Raw glass used in lampworking comes in glass rods for solid work and glass tubes for hollow work tubes and vessels/containers. Lampworking is used to make complex and custom scientific apparatus; most major universities have a lampworking shop to manufacture and repair their glassware.
For this kind of “scientific glassblowing“, the specifications must be exact and the glassblower must be highly skilled and able to work with precision. Lampworking is also done as art and common items made include goblets, paper weights, pipes, pendants, compositions and figurines.”
