I am doing a cow skull with dyed howlite for a friend. I have some small (3/4 inch) beads already dyed that I am going to cut in half. I have a few buckets up to soft ball size not dyed. Any advice on dying. There is an old thread and said tidy bowl for turquiose, one member said denatured alcohol. You think denatured alcohol mixed with tidy bowl? Anyone with thoughts on how to? forum.rocktumblinghobby.com/thread/381 |

Good question. Curious minds want to know as well.

I am still doing research on this. From what I have read, the dye process works best if the mixture is very hot for an extended period of time. There was no specific temperature or length given.

I wouldn't go with Ty-D-Bol - contains too much acid and a lot of stuff you don't need - and you wouldn't want that leaching back out from any stone onto skin anyway. Howlite is calcium borosilicate so strong acid wouldn't be recommended - hydrochloric dissolves it (same with magnesite, a similar-looking material that often gets dyed). Heard of some using aniline dye or RIT dye used for clothing followed by a sealer. People faking a lot of turquoise probably go with copper salt solutions, though. Some of the cheaper fake turquoise is only surface coated (howlite or something cheaper like plaster) with colored resin that doesn't penetrate very far into the stone.

I was at the store today and the ingredients on the Tydbowl say " Borax and Surfactants". I think surfacants are soap. It's made in Racine, might try and call them. |

They aren't required to disclose their proprietary formulations or even all their ingredients (only those relevant to hazards), so you may or may not get an answer. The main Ty-D-Bol product (the in-tank blue dye) isn't very hazardous, but it is acidic. Here is the info sheet from Home Depot. Note that the color comes from "Acid Blue 9" (C 37H 42N 4O 9S 3), which is the same as or similar to the ingredient used in most anti-algae pond tint dye (probably cheaper from your local farm supply or garden center and without the surfactant and similar unneeded Ty-D-Bol ingredients). Acid Blue 9 is very water-soluble and when blue enough to see in a drop of water will stain your skin (I can attest that the dilute stuff takes days to wash off). Even if you seal the dyed stone, eventually the sealer wears away, and I think might have nasty consequences. I think going with clothing dye like RIT with a fixative step would be more "wearable" and permanent. There are also permanent masonry stains available at home centers, but those that I have used have been acidic, which would etch/dissolve howlite or magnesite. Another possibility would be the oil/solvent dyes that are used for stone exposed to water (a granite countertop place might have info on those). Alcohol ink (same stuff as in Sharpie permanent markers) is also used to color small items of stone and ceramic. It is waterproof (though not alcohol-proof) and available pre-mixed at craft stores, or you can make your own using a dye like RIT. Would be fun to experiment with some of the methods, assuming having access to a bunch of howlite and/or magnesite lying around. |

If I get to it before I go on the road again. If not Will have to wait. Thanks |

Brazilian Agates and some tumbled stones are dyed with Aniline dyes. Frequently disolved in alcohol (Aniline is formula C6H5NH2). Used to dye fabric, carpet ...
You could try Copper Sulfate (in water) and once it is dyed, soak it in ammonia and that will convert the cu to a hydrate that is nolonger soluble. I have used copper nitrate and ammonia to get a light baby blue in chalcedony.
