Back in 2010 at the 2nd International Mountmaking Forum, I recall a discussion concerning some sort of shrink-tube substitute that was in a powder or granule form. The mount was pre-heated, then dipped or rolled in this material which was then melted onto the mount by applying more heat. I remember it was sold in a fairly large quantity. I also remember a discussion through the forum about this stuff, but I have since lost that information through a computer change-over.
Can anyone provide me with a name and a source? Also, if any of you are using this material I’d be interested in hearing your opinion on its use.
Many thanks.

It was called Plascoat and the batch that we all shared failed Oddy although previous lots had passed. We haven't pursued it further but it was damn handy while it lasted. I'd be willing to pay for a part order and have the Oddy test done by our conservators.

Hi Jim,
This is what was discussed at the forum. I can't speak for the ODDY testing, but I can say that it takes a bit of practice to get this to coat evenly. When properly applied, it works great and looks even better. I only use it for tiny spider mounts. It has a softer grab compared to B72.

Steve,
Did you do an Oddy test or are you referring to the test done by a member in New Zealand, (her name escapes me now).

Plascoat Vitroguard is no longer being manufactured. This is a very similar product http://www.protechpowder.com/EN/glaslok.html
I have experimented with it and has very similar working properties. But we have not Oddy tested yet.

Hello Philip and all,
When the discussion about Plascoat Vitroguard 12 started a few weeks back I emailed the supplier/importer in Quebec to ask if it was still available, I have been off on vacation and while away got a response from her, as follows
Good day George,
Product: Vitroguard 12
Quantity: 20 kg = 1 box
Cost: $17.89/kg
Payment Terms: Credit Card (Visa or Master Card)
Shipping Terms: UPS pre-paid and Add
Hoping this is satisfactory.
Regards,

So it is still available, because it is being sold from Canada into the States there will be customs charges, so remember to work that all out before you order it, and with the minimum quantity you will want to do a group order. From earlier conversations with Rosa there are also similar products in different colors available. And when we got the last order a few years back we did an Oddy test on it and it did well for us. And PS, Rosa Perullo has been at times a bit short to deal with but in time she warms up.

Hi George, Thank you for looking into this for the group. We have a lifetime supply of Vitroguard 12 that has been passing the long term Oddy test that our conservators run on it. But other mountmakers may want to get some while it is still available. I would run an Oddy on each batch. I have copied an older post about a batch that did not pass an Oddy test for long term. We have been using Vitroguard on mounts since 2006 without any problems.
Best Philip

Hi,
I was wondering if other people have tested the clear plastic dip, because it failed our oddy test. I thought some people here in the Forum had?
Our samples showed discolouration on the lead and copper sample, and our Preventive Conservator said it is on the border of failing. He would definately only recommend using it for temporary exhibitions up to three months, and this was also not really recommended, because of the danger of the running time of an exhibition being extended or Mounts would be recycled unknowingly.
We tested both the powder and the 'melted' dip.
Anyone had similar results?
Thanks,

British Museum online database of Oddy tests
Hello: this was recently posted on the Conservation Distlist (ConsDistlist):
Date: 29 Nov 2013
From: Capucine Korenberg <ckorenberg<-a t->britishmuseum< . >org>
Subject: New site--Database of British Museum Oddy test results
The British Museum's database of materials test results is now
available online at
It contains the results of the 'Oddy' tests and pH tests carried out
on materials in the Museum during the previous five years. Some
materials release volatile components (solvents, organic acids etc)
which, in an enclosed space, may reach levels of concentration
capable of damaging objects, corroding metals or harming organic
matter, for example. Materials testing is carried out to help
determine if materials are safe to use with objects inside
showcases, packing crates or stores.
