bloody brilliant and very helpfull

[@DianneCulbertsonJacques]

Thank you for this! I just bought mine and wanted to make sure I knew what I was doing.

Hi @DianneCulbertsonJacques, you're very welcome! I'm glad to hear that our guide has been helpful as you start working with your new graphite ingot mould. It's great that you're equipping yourself with the right knowledge to ensure a smooth and successful experience. If you have any questions as you go along or need further tips, feel free to reach out. Happy crafting, and I can't wait to hear about your projects!

Thank you for your video. Regarding 24:57, the volume capacity of the ingot mold can be measured by filling its grooves with water. The volume is measured in cubic centimeters. Pure water has a density of 1 gram per cubic centimeter and pure gold has a density of 19.3 grams per cubic centimeter. Pure gold's volume calculation is 1,000 cubic centimeters ÷ 19.3 grams per cubic centimeter = 51.8 cubic centimeters which is the same as 51.8 milliliters. A water volume of 51.8 cubic centimeters of pure water will also weigh 51.8 grams on a gram scale. Therefore if 51.8 cubic centimeter is the volume capacity of the ingot mold, then it will hold one kilogram of pure gold. Similarly for the volume of pure silver, its density is 10.49 grams per cubic centimeter. Pure silver's volume calculation is 1,000 cubic centimeters ÷ 10.49 grams per cubic centimeter = 95.3 cubic centimeters which is the same as 95.3 milliliters. Therefore if 95.3 cubic centimeter is the volume capacity of the ingot mold, then it will hold one kilogram of pure silver.

@jadenephrite, thank you for taking the time to share such a detailed and informative explanation! Your breakdown of the volume capacity for gold and silver in relation to the ingot mould is incredibly helpful, not just for us but for our entire community. This kind of insight enhances the understanding of the properties and handling of precious metals, making the crafting process even more precise and meaningful. We're grateful for your contribution and are sure many viewers will benefit from your knowledge. Thanks again for adding so much value to the discussion!

Thank you for your video! I never worked with graphite before. I will definetly try it out and see if they give me better results and how well they work. I've seen so much more variety of size for pouring, than the iron molds they offer in germany.

[@roberts_and_co]

Thank you for your kind words and for watching our video! We're glad to hear that you're inspired to try out graphite molds. They really do offer a great variety in sizes and can provide excellent results due to their thermal properties and smooth surface finish. We'd love to hear about your experience once you've had the chance to work with them. Happy crafting, and don't hesitate to reach out if you have any questions along the way!

You mentioned something that you felt was important in the process of ingot making. I couldn’t catch the word but it sounded like “pinging”. Can you explain what that is? Thanks. Just found your videos on KZbin thanks for putting them out there for us

[@roberts_and_co]

The term you heard was "peening,". Peening involves repeatedly hammering the surface of the metal with a hammer. This process can be particularly useful after making ingots to increase the density of the surface, or even to relieve surface stresses, making the metal more durable for the next jewelry-making processes of rolling and drawing.

[@stephenseymour1840]

Thank you

[@stephenseymour1840]

You would do this before putting it through the rolling mill?

[@roblobvid]

Thanks for the informative video. One question, how hot do you get the graphite before you pour?

[@roberts_and_co]

Thank you for your comment and we're glad you found the video informative! Regarding your question about heating the graphite before pouring, we currently don't have a method to measure the exact temperature of the graphite ingot moulds. Additionally, there seems to be a lack of specific guidance online or in published books about the precise temperatures to aim for. As a result, our process involves a bit of trial and error to find the right heat level for optimal results. We're continuously refining our technique based on our experiences. Your question highlights an interesting area for further exploration in goldsmithing!

P/S starting out prospecting never done it but need to in hard times.😂

[@roberts_and_co]

Good Luck!
