Discussion Overview
The discussion revolves around sourcing ultra-thin silver and gold foil for various applications, including sputtering and sealing. Participants explore the definitions of "ultra-thin," share sourcing suggestions, and discuss methods for creating custom thicknesses from available materials.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- One participant inquires about where to buy ultra-thin silver and gold foil squares, specifying dimensions of 7"x7" for gold/silver and up to 3'x6' for silver.
- Another participant suggests contacting gold smelters in the USA for potential suppliers of foil.
- A participant questions the units of measurement used for the foil dimensions, implying confusion over the term "ultra-thin."
- Some participants argue that 0.024 inches is too thick to be considered foil, suggesting it is more akin to shim or sheet material.
- One participant proposes buying drawn round wire and rolling it through jewelry rollers to achieve the desired thickness and width, citing cost-effectiveness.
- Links to various Alibaba products are shared as potential sources for silver and gold materials.
- A participant expresses interest in melting silver or gold and rolling it out, asking about the feasibility of using a specific torch for melting.
- Another participant provides advice on melting techniques and suggests using a groove for pouring melted metal, followed by rolling it to achieve uniform dimensions.
Areas of Agreement / Disagreement
Participants do not reach a consensus on the definition of "ultra-thin" in relation to the specified thickness. There are differing opinions on whether 0.024 inches qualifies as foil or shim material, and the discussion remains unresolved regarding the best methods for sourcing or creating the desired materials.
Contextual Notes
There are assumptions about the definitions of foil and shim that are not explicitly clarified. The discussion also reflects varying levels of expertise among participants regarding metalworking techniques and equipment.
