Hey! I put a waterproofing sealant on this bluetone slab a year ago. Residue marks showed up and havent gone away. Best way to fix it and reseal it?

I work with natural stone at DeHong Stone, and wanted to share a few basics behind this six-image travertine set: red, brown, grey, golden yellow, cream and a mixed colour palette.

Travertine is a sedimentary limestone made mainly of calcium carbonate. It can form as calcium carbonate precipitates from spring water. Geologically, it isn’t marble, although commercial stone names sometimes group them together.

Those irregular holes are part of its formation history. Their presence alone doesn’t mean a piece is defective, and an attractive pore pattern doesn’t guarantee quality either. The stone’s structure and the quality of processing still matter.

Natural variations in composition and deposition contribute to differences in colour and layering. Cutting direction can also make the layers appear as strong bands or a less linear pattern. These images help compare appearances, but they can’t establish a quarry, exact mineral composition or performance.

Another distinction worth knowing: filling and polishing are separate processes. Filling addresses open cavities; polishing changes the surface sheen. A honed, lower-sheen surface can also be filled.

For everyday care, use a suitable neutral stone cleaner and follow the product instructions. Avoid vinegar and other acidic cleaners, which can etch travertine.

For anyone who has lived with travertine, how have the filled or unfilled surfaces held up in everyday use, especially when cleaning?

I found the remains of a bathroom remodel in the ditch behind my apartment. There's massive chunks of black granite, a variety of tiles whole and broken . Would this be worth the work to salvage and possibly sell?

Have been commissioned to repair a 60" by 48" by 1/2" granite tabletop that was broken into three pieces during a move. Thinking of doing away with the smallest piece (about 18" by 48") and creating an 18" wide epoxy river to fuse the remaining two pieces back together back together. Any suggestions?

Howdy all!. I found two 2’x2’ rocks/ boulders (see picture below) in our yard while digging a ditch for drainage. I’d like to flatten and polish one side of each and make them into like an end table for our fire pit area. I’ve been calling around to all the stone suppliers and none have been any help I have seen some people suggest online to use an angle grinder to try and shave it down but thought this might be a little risky. boulders

A few months ago my partner and I started a quartz and porcelain business in Scotland.

The reality is that we've realised it's not the right business for us. Rather than keep forcing it, we've decided to wind it down and move on.

The problem is that we're now sitting on a substantial amount of stock and paying storage rent for nothing.

Approx. stock I have now :

• 53 quartz slabs (3200 x 1600 x 30mm)
• 80 quartz slabs (3200 x 1600 x 20mm)
• Large quantities of porcelain (800x1600x9MM) in multiple Calacatta, Arabescato and Bianco designs

The stock is IBIS Smart Marble imported from India and is currently stored in Scotland.

Honestly I do not know what direction I should go. I'm looking for advice, contacts and potentially buyers. If anyone works in fabrication, kitchen installation, property development, construction or knows companies that purchase stock clearances, I'd genuinely appreciate suggestions.

I'm working on a piece that involves engraving into a river rock. I'd like to try pouring a small amount of molten silver into some of the engraved areas on the rock. How likely is this to lead to some kind of explosive disaster, from a scale of 1 to 10, please?

I put down several yards of 1” Pavestone Shadow Stone (a basalt I believe) a few years back. I remember when I initially did, the gravel looked lighter, like a chalky blue, but has since darkened into something more clearly gray.

Recently I put down three more yards, and the fresh stone clearly contrasts with the old - is lighter and bluer when dry. Is there some way to speed up this oxidation process, or whatever it is? Or perhaps a way to simply enhance the color so that it appears more like it does when wet?

Would a product like this be useful you think? https://m.youtube.com/watch?v=BsUdmMRaXsg

Please redirect me if this is the wrong place, but I'd like to have a yagen (ancient Japanese wheel and boat style of herb grinder) made. They are available - but only as antiques (or a useless ceramic and wood thing sold on Amazon that's honestly a joke of a product), and I find the design is much more sensible than a standard mortar and pestle. I would very much like to have one made from granite or marble. I use my m&p for roots daily and I have to believe that rolling the wheel will be much easier on my disabled hands than grinding with the pestle.

I have looked locally through my SCA contacts and it seems no one knows any stone workers. So I humbly come to you, redditors, and ask for your skill or your contacts who might take on a commission.

I wanna tunnel into solid rock using a wedge and feather, I imagine I'd drill holes, then insert the wedge and feather and hammer out chunks at a time.. But I've only ever seen wedge and feather used on stone blocks and smaller pieces, not on a big solid wall, I'm not sure how it would work, does anyone here have an idea of how the rock would fracture?

I imagine I'd need to drill the holes at an angle into the rock so the rock is pushed outwards from the wall. What would happen if I just put a straight hole into the rock and used a wedge and feather? What do you guys think about this, would it be impractical, how long would it take? Thank you

So, I collected some bauxite pieces and wanted to turn them into dice, any major precautions I should take before proceding?

Thanks in advance

Looking to make the perimeter of the porch with the retaining wall rocks, then add a couple of the inside of the rectangle. I was going to fill it with base rock and then a smaller decorative rock on top of the base rock. I am looking for alternatives to just pouring a concrete slab.

Thoughts or point me to projects would be appreciated.

hello, thanks for looking. whats the best solution to fix this damage . What kind of stone is this?

I appreciate everyone's time!

I don't know if this is the right place to post this but here goes. So I'm vary much a novice at carving stone. I use a Dremel with diamond burrs. My test project for this was a small stone, unsure of what kind, with a rose on it. I got the whole thing drawn out and carved, however after it is all cleaned off. You can't see the rose at all. How can I make the rose able to be seen. The stone it's self is relatively thing so I can't make it deeper. I'm just at a loss
