  • Adult professionals are discovering that they are useful as reusable note pads

If you are younger than 60 years, chances are you never carried a slate on your first day to school — unless you went to a government school. 

This essential tool of education — the black stone slate bordered with wood and later replaced by a lighter black-painted tin sheet — is part of the memory of generations of Indians.

It served well from class one to five, and millions learned the alphabet in whatever language they chose, by repeated exercises with slate and slate pencil.


But hope is at hand for a revival!

The humble school slate is making a comeback in a new retro digital avatar as an electronic slate: The writing surface is a sheet of Liquid Crystal Display or LCD. You use a stylus — very similar to the kind that comes with touch-screen tablets and laptops.

The new generation digital slate has  two advantages: It runs on a (usually button type mercury) battery, so that once you write or draw something, you can prevent erasure by pressing an erase lock button. More usefully, if you want to clean the slate, you can disable the lock and “Clear” the display with a single button press. 

Digital slates come in a range of sizes. Shown here: 8.5 inch Storio and 15 inch RuffPad.

Known by various names: LCD writing pad, digital slate, e-slate, the device currently comes at an entry level size of 8.5-inch diagonal and a casual search of the keyword “digital slate” at Amazon, Flipkart or any online seller, throws up multiple options.  

Amazon’s own-brand 8.5 inch “Magic Slate" cost Rs 289 when I checked today — though it seems not very different from the model I bought for the purposes of this article from Storio for Rs 247, before discovering that there are options for as little as Rs 100.


Typical of this class is the Portronics Ruffpad 15 inch Writing Pad that was launched last month and is quoted at online sites at around Rs 1,250. 

It offers an added convenience, a phone app, using which you can snap a photo of your work on the pad and share or store it with email or Whatsapp. However, claims that these are “multicolour” pads should be taken with a large pinch of salt.

Professionals have discovered in the electronic slate, a useful tool as a reusable scribbling notepad.

Professionals 'Discover' The Digital Slate


These customers have also seen the markets innovate to add even more useful features for professionals, especially designers: this new class of graphics drawing tablets come with a micro-USB port and compatibility with both phone (Android) and desktop (Windows, Mac,Linux,Ubuntu) operating systems.

This opens up the tablet to importing tools like Word, Adobe Photoshop or its OpenSource equivalent, GIMP and exporting the created work via the USB port. 


There are other makers with products similar in capability  to the Huion range — Wacom, XP-Pen, Veikk — but prices go up to Rs 6,000, depending on size and features.

Indian school children try out prototypes of the I-Slate which came with a solar charger.

In 2010, Singapore’s Nanyang Technological University (NTU), Houston’s Rice University and the Indian NGO, Villages for Development and Learning Foundation (ViDAL), joined to develop the I-Slate solar-powered computer tablet designed to help children in developing countries have access to computer technologies.   

Thousands of Indian children were provided with prototypes to try out. The cost of making the I-Slate in quantities was around US 20 (Rs 1,700 today).

It was selected by the Institute of Electrical and Electronics Engineers (IEEE) as one of seven technologies that “will have world-changing implications on the way humans interact with machines, the world and each other.”

Sadly it does not seem to have taken off the way its sponsors intended.

Is The Traditional Slate Dead? Not Quite

So, maybe it is time to say: ‘The slate is dead. Long live the e-slate.’


Many diehard educationists still swear by the useful role it can play in the formative years of young children and advise parents: even if the school no longer mandates the slate, buy one for your child and let him or her ‘play’ with it at home, learning to write numbers and alphabets and giving a free rein to creativity.  

But can you even buy the old-type stone slate anymore?  

Even back in 2014, The Hindu in its Madurai edition, carried out a search for slates in local schools. The article “In search of slate” found it to be almost extinct in local schools even after it had undergone many transformations from stone to enamel, to tin to plastic and even to cardboard.    

Millennial parents born after 1981 especially the well-heeled ones, may never have touched a slate in their school days and see neither irony nor excess in gifting their kids, iPads costing anything rom Rs 30,000 to Rs 50,000, when for the child, this is no more effective as a creative tool than an old fashioned slate that can still be had for Rs 20-25.

Today the last bastion of the traditional slate is the government school system where in most states they still see value in this sturdy and cost-effective tool at least till Class two or three.

Where stone slates are still made...

Traditional stone slates are still manufactured and dispatched all over India, by dozens of small firms in Markapur in the Prakasam district of Andhra Pradesh, which is close to  many slate quarries — even though their business which provides employment to thousands, many of them family businesses, is said to be slowly shrinking. 

Some enterprises like the Bhavnagar, Gujarat-based Raja Slates have been making slates, as well as, blackboards since 1975 and have a viable  business. They switched to plastic some years ago.


That would be premature. It will live on as long as our public-funded schools put utility above fashion and take their children up the first rung on the ladder of education with an environment-friendly, affordable and eminently practical writing tool.

And for those who crave modernity, there is now the modern, electronic version of this retro writing surface. Take your pick!
