How Edible Gold Leaf is Made

If you’ve ever been interested in how gold leaf is made, the manufacturing process of edible gold leaf sheets, as well as edible silver leaf sheets, here you can get an in depth look at the manufacturing process we at CornucAupia Gold Leaf Manufacturing, Inc. use when creating our products.

Step 1: Enter the Workshop to Learn How Edible Gold Leaf is Made

To learn how edible gold leaf is made, we enter our workshop, and begin the process of creating 24K Edible Gold Leaf, Pure Edible Silver Leaf, 24K Gold Leaf for Cosmetics of Pharmaceuticals, or Gold and Silver Leaf for Gilding.

Perperation of Materials for Manufacturing

Step 2: Preparation Begins

All of the tools necessary are prepared for the melting process. These are standard pieces of equipment used for melting precious metals.

Melting Gold and or Silver Metal Bars

Step 3: Melting the Gold or Silver

We insert the raw gold or silver into an oven, where they are melted at their respective melting temperatures. They are inserted inside a crucible that glows bright orange from the intense heat. This is what allows us to insert and remove the melted gold and silver metals.

Melting Temperatures of Gold and Silver are Monitored

Step 4: Temperature Maintenance

Close maintenance of the internal temperatures is maintained so that the metals are melted at an efficient rate.

Melted Gold and Silver Metals are Removed

Step 5: Removal of Melted Metals

The melted gold or silver is removed from the oven once completely melted.

Melted Gold and Silver Metals are Poured into Mold

Step 6: Pouring a Pure Bar of Gold or Silver

The melted gold or silver is then poured into a mould to be shaped into a bar. This allows for easy handling throughout our process.

Melted Gold and Silver Metals Is Cooled in a Mold

Step 7: Cooling and Solidification

Once the gold or silver has been poured into the mold, it must be cooled for handling.

Melted Metal Bar Removed From Mold

Step 8: Removing the Solid Gold or Silver Bar

Once the bar has been cooled sufficiently, it is removed from the mold, and is ready for the next part of our process.

Metal Bar Hammered of Inconsistancies

Step 9: Hammering of the Bar

Any inconsistencies in the shape of the bar are hammered out so that it can efficiently be handled.

Metal Bar Hammered out of Inconsistancies Continues

Step 10: Hammering of the Bar Continues

It is necessary for the bar to be consistent and solid. Any possible flaws are beaten out so as not to hinder further processing.

Hammering is completed

Step 11: Completion of Hammering

Once the bar is thick, solid, and tight, it is considered ready for the next step of the process.

Metal bar is rolled through a rolling mill

Step 12: Rolling the Bar

This process is repeated until the bar has reached a consistent thickness that can be processed further.

Bar is flattned as thin as possible in the mill alone

Step 13: Further Rolling the Bar

This process is repeated until the bar has reached a consistent thickness that can be processed further.

Thin roll of gold comes out of the rolling mill

Step 14: Completing the Rolling Process

Once the gold or silver bar has completed its processing within the rolling mill, it is a magnitude thinner than when it first began as a bar.

Step 15: Removal from the Rolling Mill

The bar is now thin and ready for further processing. It must be removed from the mill with care so as not to break.

Thin gold and silver rolls are heated and softened in an oven.

Step 16: Metal Heating

The thinned gold or silver metal is now heated so as to allow it to be cut and formed into the necessary sizes for further processing.

Metal is cooled, and cut into squares, then put between black sheets

Step 17: Preparing the Gold or Silver for Beating

After the metal is sufficiently softened, it is cut up into small squares of 1inch, and inserted into a stack of beating paper.

Full stack of black paper contains 250 squares

Step 18: Completing the Stack

A full stack of gold or silver reading for beating contains 250 squares of gold or silver sandwiched between individual sheets.

Black sheets with gold or silver inside are beaten by hammering machine.

Step: 19 Hammering of the Pouch

After the stack is completed, it is inserted into a pouch so as to maintain form during the beating process. A mechanical hammer is used to beat the metals.

After beating, the gold or silver greatly expands and is very thin.

Step 20: Beating Completed

After the first beating is completed, the gold or silver squares of 1inch have now grown to roughly four times their original size, and much thinner.

Flattened Gold Sheet is cut by sharpened bamboo, as metal knives will not work.

Step 21: Cutting the Gold or Silver Leaf

The now thinner gold or silver leaf is cut into squares further so as to allow expansion during further beating. This process is done using a bamboo knife as conventional equipment would cause the now extremely fine metal sheet to cling to the knife.

Cut gold sheets are prepared for second beating, put back into black paper.

Step 22: Preparation for Second Beating

Once the silver or gold leaf is cut further, it is re-inserted into another pack of beating paper in preparation for further hammering.

The second hammering begins.

Step 23: More Hammering Begins

Once the silver or gold leaf is cut further, it is re-inserted into another pack of beating paper in preparation for further hammering.

The black sheets are hammered until the gold is thin enough

Step 24: Further Hammering Until Completion

The sheets are hammered until their desired thickness, being checked throughout the process for any inconsistencies. The analog process is the only way to ensure uniform thinness and structural integrity.

Ready gold leaf sheets are placed into a booklet with care

Step 25: Final Packaging

Once the gold leaf, or silver leaf reaches the necessary sizes for usage, it is cut into squares of 3, 3/8 inches, and packaged in booklets of rouge paper, making a single booklet contain 25 of such sheets. And that concludes how edible gold leaf is made in our factory.
