6-Piece Testing Acid Solution Set for Gold, Platinum, & Silver
This convenient set includes one of each of the following: 10K, 14K, 18K, 22K, silver, and platinum testing acid bottles (12 grams each). They come in sturdy plastic bottles with an internal baffle in order to prevent leaks and to maximize safety. Plus, it allows the user to precisely only use the drop the amount needed; so you will get hundreds of tests out of each bottle! Each bottle contains 12 grams of solution. Avoid ingestion, and contact with skin and eyes.
Instructions:
��� Scratch or rub the metal you are testing onto the stone; hard enough to make a visible streak or mark onto the stone.
��� You may also shave the metal you are testing, and use the shavings to test onto the stone.
��� Place half a drop of the closest acid to the karat you estimate the metal to be, onto the gold that rubbed off onto the testing stone.
��� If the acid dissolves the metal, the metal is less than the karat that is displayed on the bottle. You should try again with a lower level acid.
��� If it dissolves the metal slowly, it is possible that your material is gold, just not as pure as the karat rating on the bottle.
��� If the metal stays and does not dissolve, it is at least the karat of the acid in the bottle.
��� Silver Results: 90%-100% = Dark Red; 80%-90% = Light Red or Brown; 65%-75% = Light Green. Creamy white results will indicate that the item is sterling silver. Green results indicate that the item is silver-plated.

Great Quality bench for the price! PMC Supplies customer service was great. Very Easy to assemble and set up.
Excellent hands down! This is the best especially if you use resin of any brand any kind!
So far I’m loving this bench. I’ve had it less than a week but I am impressed not only by the workbench but by the customer care at PMC Supplies. The bench arrived in three boxes that were not too heavy that I needed help going upstairs. There were probably 20 wood pieces and a hefty bag of hardware, but in just about two hours I assembled the workbench myself. The top of the bench was cracked upon opening, which was odd since it was inside three boxes. When I contacted PMC Supplies about this, they offered to replace the top or refund part of my purchase price so I could repair it myself. In any case, the bench and shelf have plenty of room for nearly all my tools. I’ve been able to empty three medium to small tool bags and fully stock the bench. I’ve added a flex shaft mount and tool and I will be adding drawer pulls to the drawers to make them easier to open.
Pros
Easy to assemble.
Sturdy, all-wood construction.
Shelf has plenty of needed space for tools and storage.
Excellent customer service.
Cons
Wood is somewhat soft, maybe pine? Doesn’t really matter as any bench will show signs of wear over time.
Holes on shelves are too small for some tools, particularly hammers.
Top was cracked upon arrival but PMC Supplies made it right.
This is the perfect product for my sand casting applications! It packs the petrobond well - and easy to use. Highly recommend!
Works Perfect. Good Quality.. Will buy again
I have been on the lookout for a more affordable diamond coated tipped tweezers and I have finally found them! I'm not a jewelry maker but I use these for volume eyelash extensions. There is a lash company called Novalash that makes a pair but it is $104 and I couldn't fathom spending that on one pair. I went on the hunt like a hawk to find a pair of diamond dusted tweezers at a more affordable price and found them on your site. Please don't discontinue these tweezers and I would like to know if you are going to carry more straight tweezers with Diamond Coated tips? Thank you PMC supplies!
Great furnace great customer service.
I received the kit in 2 days. Crazy fast. I ran it through a bag of cans to see how it works. I could feed it a can every ±20 seconds. Works great. I'm confident this will be a good addition to my pour process.
This crucible is absolutely worth every penny! Been kicking the heck out of this thing for a year and a half, still rocking. I actually cracked it on the side from a thermal variance (my fault-newbie), and it healed itself again. The vitrification is essentially self healing. I am here to buy another, a larger one, right now.
Great furnace! I’m new to this hobby, so I wasn’t sure about this website or this product but both have been excellent! The furnace has had about 10 fires and other than some discoloration, no real issues. The stone in the bottom broke around the 8th fire but still does the job. This furnace can get hot enough to melt copper EASY. I haven’t tried anything else yet.
Absolutly perfect for brass and aluminum used several times and never have problems looks just like I just took out of the box 5 star
I love this furnace, I am very pleased with my purchase, it will be useful for a very long time. If unsure which furnace to get, this one will certainly not disappoint... Have fun!
Just as advertised, it works great to melt brass and copper in. I will purchase this again in the future.
Just as advertised, it works great! Speedy shipping and a great product for a great price!
