Hi there, you can use some artistic clear wax, this is the stuff used to make bottles, glass panes and drinking glasses for cinematic purposes. You know when actors smash through windows?
There is an arts supply shop in Newbury specialising on sculpture materials and a few years ago I did purchase some of this wax for a similar project to yours. Google will come handy to find it.
You can dip objects while you pour the melted wax. It comes in pieces like stones in a bag. They will go liquid by heating and you'll have to give it a steer with some sort of tool.
You can melt it in a pot on a camping or kitchen hob at 120-140 Celsius. You may need to do a single fusion for best results. The pot may not be recoverable after use.
I don't think it's suited for an area where you step constantly over it as over time it may crack and will scratch.
This material doesn't cut and it's transparent as glass. Just make sure its the clear one as there are other similar wax materials which are semi transparent.
Sorry I couldn't answer earlier
Cheers
