Making Matsuyani: Japanese Pitch

Here is my attempt at making Matsuyani, a Japanese hard pitch for repousse. The recipe comes from Ford Hallam, who was kind enough to post this, years ago on the Carving Path Forum. His ingredients are:
750 grams of Pine Rosin (Pine resin boiled down).
1,000 grams Plaster of Paris
50 grams Vegetable Oil
1 tsp Charcoal powder
Finding the pine sap/resin is time consuming. I think I covered 14 miles of forest. If you can find one struck by lightning, that's your best shot. After collecting, boil down to convert the sap/resin to pine rosin. Be warned, this stuff wants to boil over and it produces turpentine fumes. Do Not catch on fire. If you burn the pitch, it loses some of its' properties, only use a heat gun. Add all ingredients, cook down and pour into your repousse bowl of choice. The bowl in the video, I made years ago from 1" plate, welded together. Weighs a ton.
Thanks again for watching. You're Awesome. If you want to help the channel for future videos, my links are below:

That is the most aesthetically pleasing bowl of pitch.... that povely flat reflective surface. Awesome video!

Looks great. There's something to be said about hiking through the hills and collecting your sap. If I might offer, though, you can buy Pine Tar by the pint, quart, or gallon. It's just pine resin that's been extracted on a large scale. Those turpentine fumes you mention are because there's turpentine in the pine sap, and heating the wood in big ol' ovens is how they get turpentine for sale. The pine tar, once referred to as Stockholm Tar, is the single best preservative and general-duty finish for wood that I've ever run across. Not only does it give a nice color, imo, but it has anti-microbial action going on that prevents mold, mildew, and boring bugs from bothering your stuff. I use Pine Tar to treat all my tool handles in the smithy. If you thin it down with turpentine, it goes on smooth and really sinks into the pores of the wood. Add some shellac flakes if you want a shinier, more durable finish like on a table top. Sailors have used Stockholm Tar for eons to preserve their wood and rope.

Wow love to learn how to make pitch, and your workshop is so amazing, congratulations! Pure inspiration, thank you!

I did a similar process to make a sticky wax. Collected pine pitch, rendered beef fat and blended it together with beeswax. I made it when I was a kid 30 years ago, and it still is soft and still smells amazing.

The rendered fat doesn't spoil? I've never tried tallow/fat.

Thank you for this, I bought 500 grams of pure pine pitch to use in a smaller bowl. I took forever to find a video with the process and recipe.

I made it. Torch cut 1" plate, welded it into a sphere and welded a ring on top to hold the pitch. *About a week of welding and grinding.

@rigoniironworks Жыл бұрын

The project it's for is repousse, or raising shapes/forms out of sheet metal. I think I will make a repousse hammer and do a demo with it in the next video so it makes sense.

@BlackMuttForge Жыл бұрын

Would a double boiler work or too slow?

@rigoniironworks Жыл бұрын

Way too slow. Just reducing the chunks down to liquid takes 30min. I was careful not to burn the pitch this time. Use a heat gun to soften after its poured, no direct flame/like a torch.

Pardon my ignorance, what is this for?

@rigoniironworks 11 ай бұрын

Hi, it holds thin sheet for hammering on. The pitch is heated till soft, then the plate is pressed in. When you hammer in a design, the pitch gives way, letting you raise and sink an image into it.

Isn't your pitch exceedingly hard? It would be too hard for Repousse work. My pitch is 50% resin, and 40% castor oil with the last 10% being beeswax and charcoal. If I want it harder, I'll add a bit of marble dust (I found plaster would clump and it was hard to get it smooth) but marble dust works well, and I can get it free from places that make monuments and gravestones.

What is it for

@rigoniironworks 8 ай бұрын

How it works is you heat up the surface and press sheet metal into it. After it cools, you hammer designs into the sheet.

@davidsellars646 Жыл бұрын

No idea what it's for. If you need gobs of pitch, it's not hard to find. Unfortunately, the beetles have reached my property and my pines will now start dying. With the precipitation this year, they will be producing a lot of pitch to try to rid themselves of the beetles.

@nickv5123 Жыл бұрын

Pretty sure it’s for engraving/carving. I think the resin acts as a work-holding fixture. The resin can be heated up with a heat gun and it becomes malleable. While in a soft state, whatever you’re working on can be pressed into the resin and left to cool. When the resin solidifies, it is holding your work around 360 degrees. Or I could be totally wrong, in which case, disregard everything I said.
