Default Marble molds

Just getting ready to make something cool. I am sure I will need a marble mold.

What molds are you using for marbles and what other tools would you recommend??

Any molds works. Some better than others. I havnt used any of the high quality molds but i do have a block mold with 7 or so different size holes. The biggest being 1.5" i think. Others will swear by the infinite rim mold.

Other handy tools are a pair of tungsten tweezers and a tungsten pick. Possibly a couple of different size masher pliers. These are just handy tools with multiple purposes.

For marbles specifically the only tool you NEED is a torch. Lol. You can always let gravity rounds out the marble. The mold just speeds things up and helps to ensure roundness.

Just remember that for a 2 inch marble you do not use a 2 inch mold, a one inch works better. You use the rim of the mold not the bottom.

I use an aluminum plate that has 4 different sized holes bored all the way through it. It's about a half inch thick and raised up on feet. The top side of the holes are slightly beveled. It shapes a nice round ball by just using the top of the hole to shape with. I have used this shaping tool for the last 50 oldschool years. Sometimes I also use a folded up newspaper soaked in water in the palm of my hand to do the shaping with on much larger spheres, to speed up the process. but then glass does collect into itself. if you are going to try the wet newspaper make sure it is thick enough 3/8 to 1/2 inch will work. That way no steam will come through to your hand. The old gaffers used the Wall Street Journal because the ink was made from soy and wouldnt impart to the glass. I use ordinary newspaper and have never had that problem.

I stopped using anything else when I got the Infinite Rim mold. Drew explains it well on his page. http://frittsartglass.com/marbles/molds/index.html

Here is what and here is why:

Complete with pictures and my very good reasons WHY this is what I went with- after spending money on a lesser type marble mold.

I have a couple graphite paddle style ones and a cherrywood one. I like to use both, cherrywood for initial shaping and finish with the graphite. I actually just broke the handle off my cherrywood and need to get another, so sad. Many don't like using wood molds but I love mine!

A couple of used ones recently at talkglass.com for great prices. Well worth the change.

Aside from the torch/kiln/glasses, my infinite rim mold is the fanciest tool I have and it was worth every penny.

I'm a big fan of the infinite rim molds myself but don't let that limit you. Just about anything with a circular rim/opening that will not melt or catch on fire or otherwise be damaged by contact with hot glass can be used to form spheres. I recommend metal or graphite for safety's sake - though well-soaked wood is a viable option as well - just keep a bucket of water handy! I've heard of people using everything from a metal washer to copper pipe, for example.

Also: If your budget is 'cheap marble mold', go with it - start making spheres NOW! I would argue that there is value in learning how to work with the tools at hand. Particularly if you end up working in someone else's studio without your personal tools, like if you're doing a demo or a collab. piece. If you can't improvise you could be out of luck. You can always upgrade - and you can usually sell lightly used tools for a large fraction of "new" price.

My 2 cents. Jump in and start making spheres!

If you are on a tight budget, I recommend looking at the molds at devardiglass. I have the 7 hole one, works great! I think I paid $35 for it and have yet to need any size it doesnt provide.
