User questions & answers

Question:	Can I use this grit in my ultra-vibe
Answer:	The pellets are used for filler in the tumbler so that the tumbling action between the rocks and grit work more effectively.
Question:	What are the pellets for and how do you use them
Answer:	Yes it can. Just skip the coarse step as vibratory polishers work much faster than tumblers and will not round the rocks as well as a rotary tumbler. I always do two to 4 weeks of coarse in a rotary then finish in a vibratory.
Question:	can this be used with viberating rock tumbler
Answer:	Yes, it does. Use 2 Tbs. grit for every pound of rock for Steps 1 & 2. Use 1 Tbs. grit for every pound of rock for Steps 3 and 4. If you have alot of empty space in the tumbler, use the ceramic cylinders to get the tumbler to about 2/3 full. Instructions are included with the kit.
Question:	Does this work in hobby rock tumblers? If so, how much grit do you add per cycle
Answer:	These pins are attracted to magnets.

User questions & answers

Question:	Is the 1.5lbs bag for just one 3lbs barrel or is it enough ceramic material for two 3lbs barrels
Answer:	I only use this in a rotary tumbler. They do wear, but very slowly. I have about six months of run time on my current set and expect it to outlast my tumbling career.
Question:	Is it ok to use these with a rotary tumbler
Answer:	I looked it up. They're made in the USA at Polyplastics in Farmington Hills, Michigan
Question:	Where are this made
Answer:	The ceramic is generally used to cushion the stones or glass, in your case, during tumbling. It will have some abrasive action but it is very smooth. You will probably also need some silicone carbide grit along with the ceramic to smooth out the glass. If it is rough, you would start with Stage 1 or Stage 2 grit, then go to Stages 3 or 4. If it is already smooth, you can start with Stage 3 and finish with Stage 4. If you want a rougher frosted look, don't use Step 4. Run the tumbler 2-3 days at each step and check whether you are getting the effect you like. You can use the ceramic during every step. Just rinse it off the grit between stages. Hope that helps.
Question:	Sea glass artists create by dumping refuse into water ways allowing mother nature to naturally shape/polish glass in a non-gmo organic way. Can this
Answer:	Yes I guess. They are very tiny pellets and wash up nice for reuse.

Ceramic Rock Tumbling Media

Our non-abrasive ceramic tumbling media is perfect for protecting and cushioning fragile stones while tumbling. Also, use to fill your barrel to the recommended 2/3 level, carry grit & polish, improve tumbling action and quiet the tumbling process. Recommended over plastic filler media for vibratory tumblers.

Since ceramic rinses clean of grit, you can use the same batch of ceramic through all the stages. Just rinse off between stages, along with the rocks.

Do not use fresh cylinders when polish tumbling in Stages 3 and 4. Run the cylinders in the tumbler with coarser grit for a day or so to smooth off the edges. Preferably, use the fresh cylinders as fill for Stages 1 & 2 so they will have lost their edges by Stage 3.

Polly Plastics offers premium grit and filler materials for rock tumbling enthusiasts.

User questions & answers

Question:	Will this 5lb bag fill a 2 liter bottle? I would like to know the volume it takes up
Answer:	Yes
Question:	Is this media non-abrasive
Answer:	The large is used as a filler and lasts longer than the small. The small ceramics are used for cushioning and helps improve the tumbling action. If you are looking for the benefits of both, then the mixed is what I would recommend. I typically use whatever I happen to grab - small, large, or mixed and have been happy with the results on the agates I tumble.
Question:	Is the purpose of using mixed sized media to displace more volume? (Rather than just using all small sized media
Answer:	Yes, Just wash thoroughly with your rocks between steps to make sure all grit is removed. Some people do have a separate set of ceramic media to use strictly for polishing, but I have not felt there has been a need to this.
Question:	Can this mixture be used during all stages of tumbling, including polishing, or should plastic pellets be used for the last steps
Answer:	These are all 304 stainless

User questions & answers

Question:	Can these be used in all 4 stages of rock tumbling
Answer:	A bit rough for burnishing. Plastic pellets or rouge walnut shells or other plastic media products are better for burnishing.
Question:	Is this recommended for the burnishing stage for a rotary tumbler
Answer:	No, you want to use crushed walnut shells for reloading.
Question:	for reloading
Answer:	I wouldn't put new ceramic media into the polishing phase because it might scratch the polished rocks. I always keep some ceramic media that has been through a couple of cycles and has all the sharp edges worn down. I can use the worn media in the polishing phase and not have to worry about scratching the polished rocks.
Question:	Can i use this product in polishing phase only
Answer:	There is plenty ceramic pellets for 2, 3# barrels. Remember, when you load what ever you're tumbling, the barrels should be about half full. If not, add pellets to make up the difference. Wash and reuse the pellets.

User questions & answers

Question:	Will these help protect the more fragile stones? Some stones are snall and somewhat thin and have a tendency to splinter or break
Answer:	Not 100% but they keep the stones from hitting each other real hard.
Question:	I understand that I use grit with this, but do I still use water? Or does this replace the water allowing for a dry tumble
Answer:	You still need to use water.
Question:	Can this be used to give clean, rectangularly cut glass a "seaglass" look? It is a frosted look with edges that have been filed down. Thank you
Answer:	The pellets will cushion the glass in the tumbling process, but you will need to add grit to help shape and round the edges of the glass. Hope that helps!
Question:	What is used to give the stones a shiny finish
Answer:	The shiny finish on stones is done during the polish stage, and the final polish is done during the "burnish" stage. Burnishing is done using, not grit, but soap.

Product description

As recommended, the same pellets should be used throughout the tumbling process, all stages. That way, the pellet surface gets the same abrasion that the rocks do. If you used new pellets in later stages, they would be more abrasive and could actually work against the tumbling media you are using.

User questions & answers

Question:	I have a vibrating polishing tumbler. I want to play/make sea glass. Can you recommend a medium that would be best
Answer:	What medium is recommended to tumble glass to make sea glass
Question:	I can't find the instructions? how much do i use and do i use the pellets with the grit
Answer:	Instructions are included with all our grit kits but here is the recap. Start with Step 1 and proceed through Step 4. Use 2 Tbs. grit for every pound of rock for Steps 1 & 2. Use 1 Tbs. grit for every pound of rock for Steps 3 and 4. If you have alot of empty space in the tumbler, use pellets to get the tumbler to about 2/3 full. Cover the stones, grit and pellets with water. Run each step for 7 days. Rinse off the rocks between each Step. Do not use the plastic pellets in different steps because they can have grit embedded in them. Save them for your next tumble and use them in the same Stage as you did in the previous tumble.
Question:	Can the plastic pellets be used for burnishing
Answer:	Yes, I have read where people can use the plastic pellets along with soap and water to burnish tumbled rocks. The main thing about burnishing is the soap which cleans pretty much all the grit from the rocks and gives them a nice shine. The only thing I know about the plastic pellets, however, is that you should use fresh pellets for each phase of your tumbling because the various grits can get stuck in the pellets and end up scratching your finished product. So if you use fresh pellets in the burnishing phase it will help cushion the rocks while the soap cleans them.
Question:	Approximately how much grit is in each bag? 1 cup
Answer:	Stage 1 is about 1 cup, Stage 2 is about 1-1/4 cup, Stage 3 is about 3/4 cup and Stage 4 is about 3/4 cup. In addition to the weight differences, the difference in density affects the volume also.

User questions & answers

Question:	What are the pellets for and how do you use them
Answer:	The stones are a mix from all over and of small size and low quality. I suggest a google search of rock for tumbling to get either specific stones or a mix plus instructions on how to get best results. If you are just starting agate and jaspers polish well.
Question:	What is the abrasive material
Answer:	To attach a gemstone to the ring and earrings, have an adult help with gluing these accessories. We recommend a hot glue gun or an all-purpose adhesive sealant that can be purchased online or at your local hardware store.
Question:	Are the rocks included
Answer:	Is the tumbler broken or are you asking why you can’t set it for more than 10 days? None of the 4 steps take more than 10 days generally speaking. If you happen to be tumbling really hard stuff you can just add days as you go. However. If you are saying the machine stopped working and is broken ~ Return it
Question:	Are all 5 grits included in this order
Answer:	1/2 tablespoon of grit per pound of rock

• TWO LBS. Clear poly pellets. Use to fill tumbler to improve tumbling action.
• PREMIUM High Impact Polypropylene. Stands up to rough tumbling action. Protect and cushion fragile stones and reduce tumbling noise.
• Non-toxic, non-static and non-residue pellets are dryable and easy to reuse – float to the top for easy cleaning.
• Made in the USA. No scrap, imported or re-processed, used plastic.

User questions & answers

Question:	Can this be reused multiple times, or does it break down pretty quickly? Would like to use it for filler with mixed rocks in my rock tumbler
Answer:	I have successfully reutilized Poly Pellets numerous times. I Make sure to rinse them really well and let them Dry before storing them in a plastic jar marked for that step of tumbling and only reuse the pellets in the same step. Your rock results come out better that way and the pellets seem to hold up longer. Of course the more abrasive the step, the less longer the pellets last. As I rotate my pellets up a step as they begin to shrink in size from use, I always save my new pellets for the fourth and of fifth (burnishing) steps. Hope this helps.
Question:	Would this polish for Aluminium objects well
Answer:	The pellets don't actually polish but work as an aid when tumbling with the polishing medium.
Question:	How many beads do you use with 3 pounds of rocks, also which stage do use them with, 1, 2, 3 and or
Answer:	Just enough to fill the drum to 3/4 full, rocks and beads. Sometimes I use them on stages 2 3and4.
Question:	can the pellets be sifted from the media? and reused
Answer:	I sift out the pellets from each coarseness of medium, rinse them off and save them in a zip lock bag identifying which coarseness they were used with. That way I just find the appropriate bag and reuse them.

Polly Plastics plastic rock tumbling pellets are perfect for protecting and cushioning fragile stones while tumbling. Also, use to fill your barrel to the recommended 2/3 level, improve tumbling action and quiet the tumbling process.
