Door and Oven Glass

Each stove has a fitted pane of clear ceramic glass to allow you to see the fire. Depending on your stove model the size of this ceramic glass pane will vary in size, the cooker models will have an additional pane of ceramic glass. 

 

Ceramic glass is a service item, if it becomes damaged replacement pieces are available. For more information look at our Spare Part page. 

Maintenance

We recommend regularly removing any ash deposits that have built up on the stove glass. Always do this when the stove is cold using one of the methods below.  

 

  1. Use an approved glass cleaning solution.
  2. Make a paste from wood ash to clean the glass. This can be as simple as getting a damp rag or piece of kitchen towel, dipping it in the wood ash and then using it to clean the glass 
  3. Do not use abrasive materials, as this can scratch the glass and cause damage

"Crazing" in Glass Ceramic Materials

"Crazing" is a rare occurance and will not happen in every stove. It is highly unlikely that it will happen to your stove, as it needs a specific environment to develop. However we have included some further information below. 

 

During the combustion process, fossil fuels evolve combustion by-products. These vary both in their composition and concentration, and are heavily dependent on the composition of the fuel being used, and the burn conditions within the appliance.

 

One of the most reactive combustion by-products found is sulphur. Under certain very specific conditions, it is possible to set up a combustion environment where a chemical reaction between the glass ceramic and sulphurous deposits, which attach themselves to the glass surface (through condensation), can take place.

 

Initially, this may manifest itself only as a series of white deposits on the glass (which can be cleaned off with ease). However, if these deposits are left on the glass surface over a prolonged time period and subjected to repeated thermal cycling in non-ideal burn conditions, an effect know as "crazing" (fine cracks appearing in the combustion surface of the glass ceramic window) can occur. 

 

However, the necessary combination of effects required for this phenomenon to arise in the first place, makes this a very rare condition indeed.

 

As the chemical resistance of all glass ceramics, galls within a very narrow range, the solutions are limited here. In extreme situations, one can look at the potential of using a high acid resistant glass such as Borofloat, however factors such as thermal shock, really need to be carefully considered before this option is considered. 

 

Factors to be considered for minimising "crazing" in glass ceramic windows:

 

  • Minimise the use of high sulphur content fuels
  • Ensure glass ceramic windows are regularly cleaned using approved (non-abrasive) materials, and any residues are completely removed prior to use
