Hi all,

Now I've digged my old thread to tell you some news. My wrap project is still the brakes on due to difficult technology and it's sad...

During last weeks I've written a message to Mazzucchelli Co and asked them about vintage wraps and about possibility to re-producing em (the oldest Italian celluloid company Mazzucchelli indeed still live...). I don't know why but they immediately redirected me to Delmar and I had a long correspondence with Mr. Donald Milligan who asked me a bunch of questions and after searching finally said that Delmar has no old samples in their library.

But he said me one interesting thing -- Delmar can and ready to to start a re-producing a requested vintage wrap than an order will be not less then 400 pounds... I replied him --- hey Don, so let you start to make it again as a new cool brand !!... :)

Well, let's thinking, my friends... maybe our old Sonors, bunch of Tromsa brends, Trowa, Lefima-Tacton, Amati still waiting a new original shirts from us?

Cheers,

George.

Father42,

From what I read, you are doing a black stripe over silver sparkle ?

In one of the Sonor cats. this wrap has the name black sparkle silver striped.

The word schwarts shows up in many color descriptions !i

Yes, it's fully correct in English - you can see a such page from one of catalogues which I've posted in the beginning.

George.

So did you stripe black over silver ?

It seems to me that the wrap was black based and a stripe bar over the wrap made the Silver stripes Correct ?

No, I've probed many different ways and all results were not bad but my friends-technologists haven't no time to help me in realization an experiment in whole.

No.

The original wrap is the grand enigma...The cross section creating to me an impression that material is a volume laminated product through all the massive of his thikness - glitters/black stripe/.../... startlingly...

George.

I thought linoleum made by Delmar was a four step process. there was a backing, then a binder, then color/finnish, then the clear sheen. The backing with binder got heated then colored/finnish applied (spray or rolled) and then heated again to seal tyhe clear on. I would think that the black got the silver stripes in the middle of that long as rolling table that goes through ovens !i

At first I also thought so, but the microscope said - no... :)

George.

Where the confusion lies, is that there are many different ways of making what we call wrap. This stems from different material formulations as well as different ways of producing a given formulation.

I suspect that the reason for the 400 lb. limit, is because that is 1 batch run in a mold.

The original old fashioned nirocellulose wraps were molded in a thick resin block( hand blended and stirred) and then peeled into sheets , like veneer. There was no backing,no binder, these being for lesser quality wraps that began to emerge in the 1960's.

The original Silber Schwarz( Sonor name, for the silver and black version that Sonor catalogued), Gold Schwarz( original gold and black version that Tromsa catalogued----although catalogues are few and others did exist) and Rot Schwarz, Silber Schwarz, Gold Schwarz and Turkis Schwarz( original red,silver,gold and turquoise versions, that Luxor, a stencil of Tromsa catalogued)-------(I have no authoratative reference for Trowa), were made by laminating black and glitter layers , alternately and then slicing the block on the bias.

This must be one of the most expensive wraps to produce, not due to the copper content, as is the case with Champagne Sparkle( the pink version) but because of the labour involved in stacking the layers and then slicing edgewise.
