2.2 Lb/1000g Rock Rosin Pine Resin Pine Gum Violin Cello Bass Dance Resin for Dancers, Musicians, and Athletes to Help Grip from Slipping Maintain Balanced

For all you goat tyers out there who use rosin, these rocks are great! My daughter, Brooklyn is a Texas State champion and she has used these for years. Lasts a long time. Use a leather glove to heat up and rosin your string.

Colophony is a classic flux for soldering and this one certainly works well for the old stock lead/tin 60/40 solder. I am not sure how well is this suited for the lead-free solders. There are big rocks in the bag to use directly to clean the soldering iron tip, or the smaller grains can be carefully melted and poured in a handy metal can. The only relative downside is that there is too much of it in the bag just for the occasional soldering.

Good quality pine resin at a good price. Melts well at temperature, nice and tacky when melted. Mixes well with oils and waxes

I was quite surprised when I happened upon this item. Nicely refined, I plan on incorporating this into some custom fire starters for EDC/Camping. Not exactly sure what the formulation ratios will be, but I want it to be flexible yet flammable enough so that it doesn't take much effort to start with a ferro device. Also don't want anything that is overly messy to handle!!! I think this will be a useful ingredient to incorporate.

Elementary music teacher. I'm out of rosin and out of budget! I bought this bag and melted it down outside on my grill burner (in a junk pot that will never return to be anything other than a rosin pot) then poured the melted rosin into silicone candy molds. It worked great and the kids loved them as practice prizes. There were a few impurities at the bottom of the pot- a bug and some seeds, maybe? But they sank to the bottom and didnt affect the quality of the final product.
