12-in-1 Graphite Marble Mold
Also known as "Thor's Hammer," this beast of a tool is well worth the value. It has 6 different sizes on 1 side, and 6 different sizes on the opposite side.
- Made in the USA
- The outside dimensions of the graphite are roughly 2" thick x 4-1/8" x 4-1/8".
- The sizes on 1 side are 1/2", 3/4", 1", 1-1/4", 1-1/2" and 1-3/4".
- The sizes on the opposite side are 3/8", 5/8", 7/8", 1-1/8", 1-3/8" and 1-5/8".
Great for glass blowing, molds, and precious metals molds, etc. Graphite is easy to machine, but very dirty and abrasive to tools and machines. Graphite uniquely withstands great temperatures as well.
Ratings & Reviews
High quality tool.
by Mike H -
After using one of these molds for nearly 4 years of daily use and thousands of items made with it, it is still like new. Very little wear. As with all Weaver graphite tools I've owned, this is made with very dense, quality graphite. It is heavy, solid and well built. I refer to it as "Thor's hammer" because of the shape and weight. Great value for the money with many sizes in both 1/4" and 1/8" sizes.

This marble mold tool is just amazing. Everything about it is awesome, and it is Thor's Hammer! The graphite is so strong, smooth and high quality. It has every size marble mold imaginable and each round is flawless. Have been using it non-stop since I got it and I know I will never look back!
Marble maker must have

This tool is well worth the money. I've been making marbles for going on five years now and this is a must have. Very heavy duty. What still gets me though is the fact that there isn't an option to buy a longer handle. There have been times where I've wanted to hold the tool while spinning a large marble and it doesn't work out because my hand will be too close to the hot piece of glass. I give it a 4.6/5 until a longer handle is an option.
I have two!

I like this one so much I bought another after I dropped and cracked my first. Excellent quality.
Great marble mold

This thing is a beast. Quality graphite with plenty of sizes to choose from. It's heavy enough for benchtop use, but not so heavy that it would be uncomfortable to hold for a while. The edges can be use for marvering too!

It may start to sound corny but for real, this thing IS like Thor's Hammer. If someone tries to abduct you while working.....you get the idea. But seriously though; With the number of various sizes and the quality of the graphite, this tool is an amazing value for 75 bucks. Plus, the sharpness of the edges and the smoothness of the sides gives you way more surface area to utilize than just the mold holes themselves. If you are limited to the 12 given spots, then get creative and learn why this tool should be more like the 16 to 20-in-1 tool. Use for quick rounding pendant lenses prior to flame polishing, condensing and slightly assisting in necking small things on the fly, flat side for flat pressing/marver surface. Just look at it and tell me you don't see more for the dollar than advertised. You know you want one now!
Thor's Hammer of Glass Blowing
by Donny M -
Seriously, they should just name this thing "Thor's Hammer". I finally gave in to buying this and I don't regret it. I don't think that I will ever need to buy another marble mold again. It's so versatile. The reviews are absolutely true. I took this out of the package and was amazed at how thick and huge this tool was. If you're looking to get a marble mold, please for your own sake spend the money and get this one. I promise you will not regret it.
A Must-Have for your Marble Making Arsenal
Absolutely the best marble mold I've found. I've used a few different styles and brands while working at various studios and landed on this one for myself. It's HUGE and very durable. Even though it's massive, I haul it with me when I go to other studios to work, because I don't want to use any other mold while this one is available. I highly recommend this for both it's durability, and flexibility in marble sizes

A beast of a marble mold
by Daniel -
This marble mold is a Jack of all trades! I purchased it for just marbles but over time it became my marver or mashers. It can be used for a lot of different things honestly. I also accidentally dropped it on hard cement floor and it only chipped a corner thankfully! This thing is worth it !
