I literally have been having so much trouble because I’m heating my piece up too slowly and burning off the flux. This made so much sense. Phil, you are always a lifesaver!

[@sandmaker]

Another great video. It might be a little bit better with some close up work to it actually see it happen. Keep the goodness coming.

[@hamiltongemstones8479]

Thanks for continual uploads of great info! We appreciate it.

[@RioGrande1944]

You are most welcome!

[@kimauger4293]

love the tip about mineral oil in the glass jar to prevent drying out the tip of the needle.

Thank you for sharing your knowledge

Thanks for sharing your knowledge about paste solder.

Great video as always Rio!

The mineral oil is a big game changer! Love this video!

[@RioGrande1944]

We are so glad you enjoyed it!

[@briannapierce805]

Thanks

[@ulugbekdavlat2111]

Fantastic

[@stephencoster9532]

Thank you. What mineral oil do you use? I use a broken saw blade to place the paste solder, and who doesn't have them around? Stay safe, Steve...

Question: when soldering the earring post, did you put paste solder on the post or on the backplate?

[@dawnleece9761]

Thank you for this video. I am very new to soldering. I am working with copper wire. I have a solder paste that says it will mimic the color of brass, silver, copper or gold. It is not doing that. It looks silver after I am done. It also does not always flow even after fluxing. The solder hardens on me. How can I stop this? Is there a specific solder for copper that can be used? Can you use olive oil in a plastic cup instead of mineral oil in glass jar to store the unused portion in the tip?

[@marybryan5879]

Very helpful. Would have been more helpful if camera zoomed in while soldering.

[@samuellaramsey5824]

thanks so much!

[@kizzywitch]

Great video, please can you tell me what mineral oil you use to reconstitute it, I have a tube that is completely dried up

[@bambukouk]

is "mineral oil" what we (here in UK) call liquid paraffin, please?

[@sarahbethfederman]

What do you mean by "fire coating" it?

[@RioGrande1944]

Hello. Thank you for the question. They are referencing barrier flux.

[@lizw2853]

@@RioGrande1944Is barrier flux something different from ordinary flux?

[@lunasky5635]

@@lizw2853yes. Regular flux is designed to encourage solder to flow. Barrier flux (also called stop flow) is designed to keep solder from flowing all over the place. Rio Grande has a video on their website about mixing your own and also sells products that is ready made.

[@seaglassmomma4040]

Do the items need to be dipped afterwards with the soldering paste?

[@asaffrige2073]

Hi, i have this product but i've forgot it open and now it dried. There is something i can do to refresh it

[@maryjanebutler2180]

What to use so peace doesn’t fall apart when soldering on same peace.

[@jaderene]

As others have mentioned, zooming in to actually se go the solder paste was applied would have been helpful, but overall great video with informative tips!!!!

Hello, I use Google Translate. I had a question. When I melt the silver, after casting and cooling, I saw dark spots on it. What is the cause? What is the solution? Thank you.

[@RioGrande1944]

Hello, thank you for the question. Here is an explanation from our tech team: When sterling is melted without protection and oxygen pickup occurs, the copper will oxidize. Copper oxide in the casting can cause two problems. First, copper oxide inclusions will occur throughout the casting. They really only cause a problem when they are near the surface, where they act as hard spots that stick above the polished surface. Second, a layer of copper oxide can form in and around shrinkage porosity. This is seen on a polished surface as gray, cloudy spots. These spots are usually too deep to be polished out. Figure 8 shows a cross section of a sterling ring; shrinkage porosity can be seen throughout. Also evident are two darker areas: one at the up- per right and the other in the lower left of the casting. These dark areas indicate copper oxide surrounding surface porosity. The presence of cuprous oxide can be confirmed with an optical microscope using polarized light. Figures 9 through 11 show the various views of sterling silver with normal illumination and with polarized light. The first photo of each sequence (9A, 10A, lIA) shows various inclusions that appear black. The second photo in each sequence (9B, 10B, IIB) shows the inclusions as bright red in color, confirming that they are cuprous oxide. In some cases, when the molten sterling is left unprotected for an ex- tended amount of time and/or is overheated, the copper oxide formation is so severe that the surface of the molten sterling develops a rather tenacious skin. This copper oxide skin greatly reduces the fluidity of the metal. The usual result is that many of the fine details on the castings do not fill. In some instances, major portions of the casting do not fill. A telltale sign of this condition is a reddish color on the surface near the incomplete fill. For further assistance regarding any casting problems, it’s advisable to contact your metal supplier.
