They seem to be normal crayons just in the shape of rocks to help with grip for small children. So that would suggest no. I have not tried.
They are solid. That means they don't break easily and wear down slowly.
Yes, we have been tested for ASTM D 4236, ASTM F 963, CPSIA, EN71 by Bureau Veratis, an international product testing organization, and for all we are certified lead free.
Made in Hestand, KY, USA in a shop on a hill in rural Kentucky.
Yes, they are vegan!
ALL crayons are choking hazards IF inhaled. To date, we have never had a report of any child inhaling them and that’s 14 years and millions of crayons. BUT we don't recommend giving them to children under 3 years of age OR to any child that cannot understand and follow this direction: "these crayons are not food, do not put them in your mouth." Some children do munch them up, but at that point, they are no longer a choking hazard and since they are non-toxic they aren’t a swallowing hazard either (although they don’t taste very good!)
Yes, they are.
No, the size was very carefully chosen by special education teachers and occupational therapists to fit the grip of children between the ages of 3 and 8 and promote a tripod grip. It is actually the best size for that age group, which is why we say, “Simply the best first coloring tool for young children”.
I wouldn’t use them for that. They are usual crayons in unusual form. And,yes,you can wipe them off from smooth surfaces.
The manufacturer of Crayon Rocks. I have used our crayons to coat wood but I don't think the finished result is completely satisfactory. Usually the color continues to come off on things as you use the toy even if you "sink it in" with say a hot air hair dryer. If you are really committed, I would put the color on first an then add ANOTHER layer of wax that has no color. Probably you shouldn't use it on toys or things that are going to get rubbed a lot. Unique idea though. !
It handles well; same as paper
That is called “bloom” and it occurs with any soy product, often seen on chocolate. It has to do with the fats in the soy wax. Once the crayons are rubbed or used, that tends to go away and not reappear.
They are 1 ¾ inch by ¾ inch by ¾ inch. About the same volume as a stick crayon just compact. Larger than a quarter ($.25) but smaller than a fifty cent ($.50) piece.
The crayons are solid but all wax shrinks as it cools thus leaving a small hole at the spot that cools last.
Yes. To be fair, all crayons sold in the USA to children as toys are required to be tested and proven non-toxic (see ASTM F963 Toy Safety Standards). And ours conform to the highest standards worldwide which is EN71 (European Toy Safety Standards). However, beware of some crayons that are being sold as “stationary or office supply” products and are not being tested. Those crayons should be banned from sale until they can prove they are not a hazard.
The soy wax that is used for Crayon Rocks isn’t classified as a non-GMO product, and that’s a good thing!
GMOs and other advanced biotechnology tools have had an enormous impact on agriculture, including complex issues around environmental sustainability, plant diseases and pests and contributing to innovations with nutrition and breakthrough human medicines. Genetically modified crops can reduce the environmental impact of farming and are helping to reduce food waste and improve air quality.
Over the last 25 years, GMOs have reduced pesticide applications by 7.2% and helped increase crop yields by 22%. GM crop technology has improved yields through improved control of pests and weeds. As a result, farmers who grow GM crops have reduced the environmental impact associated with their crop protection practices by 17.3 percent. By making targeted improvements to crops through genetic engineering, farmers can produce more food for a growing world population while reducing agriculture’s impact on the environment.
